Personal protective equipment for IDLH conditions: pressure-demand self-contained breathing apparatus with a full facepiece If the concentration of harmful substances is IDLH, the worker must use the most reliable respirators. Such respirators should not use cartridges or canister with the sorbent, as their lifetime is too poorly predicted. In addition, the respirator must maintain positive pressure under the mask during inspiration, as this will prevent the leakage of unfiltered air through the gaps (which occur between the edges of the mask and the face sometimes). Textbook NIOSH recommended for use in IDLH conditions only pressure-demand self-contained breathing apparatus with a full facepiece, or pressure-demand supplied-air respirator equipped with a full facepiece in combination with an auxiliary pressure-demand self-contained breathing apparatus.

The Aqua- Lung was not the first underwater breathing apparatus, but it was the first to be widely popular. In 1934, René Commeinhes developed a firefighter's breathing apparatus which was adapted for diving by his son Georges in 1937. It was used by the French Navy during the first few years of World War II. The twin-hose Aqua-Lung demand regulator forms the foundation of all modern scuba regulators. A diaphragm is used to control a valve to deliver the breathing gas to the diver on demand, at ambient water pressure.

Breathing Apparatus Tenders (BAT) carry extensive stocks of spare breathing apparatus (BA) cylinders at large incidents. They replenish cylinders which may have been used by firefighters tackling a protracted blaze or dealing with Hazardous Materials. Some BATs are also fitted with compressors which allow empty BA cylinders to be recharged on scene. Most also contain a mobile workshop so that BA sets can be repaired at the scene of incident so that they can be made available for use again at the incident within a very short period of time.

An early use of the breathing apparatus was in the aftermath of an explosion at the Maypole Colliery in Abram in August 1908. Six trained rescuers at Howe Bridge trained men at individual collieries in the use of the equipment and at the time of the Pretoria Pit Disaster in 1910 several hundred trained men participated in the operation. Mine rescue teams are trained in first aid, the use of a variety of tools, and the operation of self-contained breathing apparatus (SCBA) to work in passages filled with mine gases such as firedamp, afterdamp, chokedamp, and sometimes shallow submersion. From 1989 to 2004, the SEFA backpack SCBA was made.

Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply. It, therefore, includes the range of physiological effects generally limited to human ambient pressure divers either freediving or using underwater breathing apparatus. Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment. All of these may affect diver performance and safety.

Theodore Schwann, a German professor working in Belgium, designed breathing apparatus based on the regenerative process in 1854 and it was exhibited in Paris in the 1870s but may never have been used. Henry Fleuss developed Schwann's apparatus into a form of self- contained breathing apparatus in the 1880s and it was used after an explosion at Seaham Colliery in 1881. The apparatus was further developed by Siebe Gorman into the Proto rebreather. In 1908 the Proto apparatus was chosen in a trial of equipment from several manufacturers to select the most efficient apparatus for use underground at Howe Bridge Mines Rescue Station and became the standard in rescue stations set up after the Coal Mines Act of 1911.

Maurice Fernez (30 August 1885 - 31 January 1952, Alfortville, Paris, France) was a French inventor and pioneer in the field of underwater breathing apparatus, respirators and gas masks. He was pivotal in the transition of diving from the tethered diving helmet and suit of the nineteenth century to the free diving with self-contained equipment of the twentieth century. All Fernez invented apparatus were surface-supplied but his inventions, especially his mouthpiece equipped with a one-way valve, inspired the scuba diving pioneer Yves le Prieur. He was also a talented businessman who created a company to manufacture and sell the breathing apparatus he invented, and expanded its range of products to include gas masks, respirators and filters.
|
|
In 1925 Fernez demonstrated his apparatus at the Industrial and Technical Exhibition in Paris. The demonstration was observed by Yves Le Prieur. Le Prieur had an idea and asked Fernez to join forces with him to work on a new concept of a breathing apparatus fully autonomous from the surface,The English term used today for any free-swimming diving device, that is, autonomous from the surface, is the acronym scuba (standing for "self-contained underwater breathing apparatus"), coined for the first time by the American Christian J. Lambertsen in 1952, year of Fernez's death. with an air tank doing away with the need for the tube connecting the diver to the surface.

The pyrotechnic equipment is not tested on board but the personal equipment (immersion suit, life jacket) are regularly tested when there is exercises for abandon ship or if the master decides. The firefighting equipment is tested once a week (mask and breathing apparatus). The fire hoses are rarely tested inside the ship.
|
|
An old photograph seems to show the cylinders (and perhaps also the weights) in a tied or laced canvas casing rather than held on with metal clamps, and a rectangular fullface mask as with the CDBA. There is a British armed forces manual about the SCBA, dated 1984 as if the SCBA was still in use then, showing separate eyes-and-nose mask and strapped-in mouthpiece and no canvas pouch, and separate sport-type weight belt with buckle-shaped weights all at the back. The design of the Swimmer Canoeists Breathing Apparatus likely changed down the years. The LOSE (Lightweight Oxygen Swimmers Equipment), a diving rebreather formerly made by Siebe Gorman, was similar to a Swimmer Canoeist's Breathing Apparatus including the cylinder backpack.

On a fireground, the sound of an activated PASS device indicates a true emergency and results in an immediate response to rescue the firefighter(s) in distress. In the United States, the National Fire Protection Association sets standards for PASS devices in NFPA 1982.NFPA 1982 (registration required) The PASS device is normally used in conjunction with breathing apparatus; it is a small, battery powered device attached to the self-contained breathing apparatus (SCBA) harness which enables the firefighter to summon help by activating a loud, piercing electronic bleeper. Early models were only able to be activated manually; more recent PASS devices automatically activate if the device does not detect motion for 30 seconds, so that the alert will sound if the firefighter is seriously injured or otherwise incapacitated.

Continuous transmission is a mode where one diver transmits continuously. This is hands free, but all audible noise will be heard by others on the same channel and within range. Open circuit breathing apparatus generally produces considerable exhalation bubble noise. Through-water systems are also used for back-up to the wired communications via the umbilical generally used in closed diving bells.

During this time, his breathing apparatus was leaking and he returned to the submarine after completion of his task very exhausted. On withdrawing, Fraser found that one of the limpet carriers which was being jettisoned would not release itself. Magennis immediately volunteered to free it, commenting: "I'll be all right as soon as I've got my wind, Sir."Ashcroft 2006, p. 289.

While docked at the port of Los Angeles in August 2005, maintenance on a sewage pipe caused a small amount of raw sewage and an unknown amount of hydrogen sulfide gas to escape. Three crew members were killed and 19 others were injured. Reports said that the deaths were almost instantaneous as the crew members were not wearing breathing apparatus at the time.

As a result, he lived in a specifically designed area of Attilan, requiring a special breathing apparatus to leave the water. The apparatus, cumbersome at first, was eventually reduced in size by fellow Inhuman, Maximus the Mad. Triton's mutation after Terrigenesis was so severe that his parents disallowed his brother Karnak from going through it. Triton later first encountered the Fantastic Four.

He also has retractable flippers, released at the click of his heels (ep. 3). The headgear includes a radio transceiver, but most remarkably, there is no breathing apparatus or face shield. Oxygen is supplied through another of Professor Fumble's inventions: "oxy-gum" which Marine Boy can chew and receive hours of oxygenation. He tends to have to replenish the gum after heavy activity.

She was once again admitted to the intensive care ward at QMH on 2 February 2008, where her condition worsened. On 19 February, at 3 am, her family decided that Shum's life support should be withdrawn. It was decided that her breathing apparatus would be removed and that her family spend time with her by her bedside. Shum died at 8:38 a.m.

The sawtail grouper is considered to be an excellent food fish and is an important target species, among other grouper species, for small scale fisheries in the northern Gulf of California. It is also a popular quarry for game fishing. Poachers fish illegally at night for sawtails grouper using spears, hookah breathing apparatus and lights, taking a significant number of fish.

Defogging of bonded lenses is the same as for plain glass. Some dive computers have relatively large font displays, and adjustable brightness to suit the ambient lighting. Open circuit breathing apparatus produces exhalation gas bubbles at the exhaust ports. Free-flow systems produce the largest volumes, but the outlet can be behind the viewports so it does not obscure the diver's vision.

Taravana is a disease often found among Polynesian island natives who habitually dive deep without breathing apparatus many times in close succession, usually for food or pearls. These free-divers may make 40 to 60 dives a day, each of 30 or 40 metres (100 to 140 feet). Taravana seems to be decompression sickness. The usual symptoms are vertigo, nausea, lethargy, paralysis and death.

In 2010 the Brigade purchased a heavy distribution unit (HDU), a Mercedes-Benz Actros flatbed lorry used for general distribution of bulk equipment to major incidents. Along with the HDU, there also exists RPE breathing apparatus support unit vans and brigade resilience lorries. These lorries are multi-purpose cargo carriers similar to the OSU but do not specifically have to engage in firefighting and rescue-related activities.

After being commissioned, under the command of Oberleutnant zur See Günther Fritze, the submarine took part in training exercises with the 8th U-boat Flotilla until July 1944 when it was assigned to the 11th U-boat Flotilla. Command was handed over to 27 year old Kapitänleutnant Karl-Adolf Schlitt. The boat was then fitted with a Schnorchel underwater-breathing apparatus before being released for patrol duties.

During the Second World War, he made some specific suggestions for a practical underwater breathing apparatus. This made the Office of Strategic Services nervous, as just such an invention was already a classified project. After some interviews, OSS concluded that he had not received unauthorized access to classified information, but told him to keep quiet about the idea.Science Digest Vol. 58, No. 1, July 1965, p. 13.

They are taken away while Vorus answers a call from Tyrum, chief Councillor of Voga, who arranges for them to meet. Lester and Stevenson capture Kellman. The Doctor explains that the Cybermen fear Voga because gold plates their breathing apparatus and suffocates them. The Doctor cannot get Harry and Sarah back without the pentalium drive, but Kellman feigns ignorance, trying to buy time until the Cybermen arrive.

The Allies used the CDLs to protect the Ludendorff Bridge after it was captured during the Battle of Remagen. The Germans used virtually every weapon at their disposal to try to destroy the bridge. This included sending frogmen using Italian underwater breathing apparatus to plant floating mines. But they were discovered by US Army military police, who used Canal Defence Lights to find and blind the swimmers.

Siebe plc became the name of the new conglomerate formed when Siebe Gorman began taking over other firms in the early 1970s, to distinguish it from Siebe Gorman's original breathing apparatus and diving gear core business. Siebe plc was once one of the United Kingdom's largest engineering businesses and was a constituent of the FTSE 100 Index. In 1999 it merged with BTR plc to form Invensys.

Due to his "condition", he is required to wear a protective suit and breathing apparatus at all times, unless he is alone. He also seems to take to Cadel very quickly and will not leave him alone, not even in Hardware Heaven. Gazo assists Cadel in his scheme to rid Axis of certain staff members. He was also the one who alerted Thaddeus to Cadel's kidnapping.

Like any other breathing apparatus, the dead space must be limited to minimise carbon dioxide buildup in the mask. In some cases the outlet suction must be limited and a back-pressure regulator may be required. This would usually be the case for use in a saturation system. Use for oxygen therapy and surface decompression on oxygen would not generally need a back-pressure regulator.

In H2SO4 units, only the reactor-settler system requires neutralization. In addition, extensive safety equipment (breathing apparatus, etc.) is required whenever maintenance is performed with a potential of HF release. Once work is completed, the maintenance worker must go through a neutralization chamber to cleanse the safety equipment. A face shield and gloves are the only typical requirements when performing maintenance on an SAAU.

Divers are trained and assessed to the requirements of Australian Standard AS 2815.5 in diving using surface-supplied underwater breathing apparatus (SSBA) to depths of 50 metres in conditions where surface compression chambers are required by AS/NZS 2299.1. This qualification allows work offshore in the oil and gas industry. ADAS Part 3 is equivalent to the United Kingdom's HSE Part I diver qualification.

U-1006 participated in one war patrol which resulted in no ships damaged or sunk. U-1006 had Schnorchel underwater-breathing apparatus fitted out sometime before October 1944. On 9 October 1944, U-1006 left Bergen, Norway, for what would be her first, and only, war patrol. Eight days into her patrol, south- east of Faeroe Islands, in the North Atlantic, she was detected by .

In 1959 Hugh Oswell designed around the Cousteau-Gagnan patent and made sport diving breathing sets accessibly inexpensive. Submarine Products Ltd were the first company to make scuba sets readily available to the public in the United Kingdom. They developed a unique diver delivery vehicle (the Subskimmer), and were important for introducing high quality plastics (e.g. ABS) into the manufacture of underwater breathing apparatus.

Recreational scuba diver A scuba set is any breathing apparatus that is carried entirely by an underwater diver and provides the diver with breathing gas at the ambient pressure. Although strictly speaking the scuba set is only the diving equipment which is required for providing breathing gas to the diver, general usage includes the harness by which it is carried, and those accessories which are integral parts of the harness and breathing apparatus assembly, such as a jacket or wing style buoyancy compensator and instruments mounted in a combined housing with the pressure gauge. In open-circuit demand scuba, the diver expels exhaled air to the environment, and requires each breath be delivered on demand by a diving regulator, which reduces the pressure from the storage cylinder. The breathing air is supplied through a demand valve when the diver reduces the pressure in the demand valve during inhalation.

Work on human factors and personal protective equipment (PPE) at the IOM started in the early 1970s, with studies of the impact of resistance to breathing caused by respirators, and resulted in guidance criteria that form part of respirator product standards to this day. In the 1980s and 1990s work continued with investigation of the utility of cooling garments such as ice jackets in hot environments, studies of the use and effectiveness of hearing protection, of the effectiveness of respirators in reducing exposure in the workplace, and of heat strain imposed by breathing apparatus. This latter work resulted in the development of permissible work times consistent with safe use of breathing apparatus, standards currently used by the UK Mines Rescue service. The PPE research has used ergonomic principles to design protective clothing and equipment that impose fewer demands on those required to use them.

It was provided with a helmet, which featured a large forward window to provide view.Flight 1 October 1936, p. 348. It is complete with closed-circuit breathing apparatus, the oxygen jet being delivered via a small injector for circulation purposes. Once exhaled, the gas would travel via an external tube to a canister containing carbon dioxide-absorbing chemicals to restore it to a pure oxygen state prior to being re-circulated.

The Frenchman Benoit Rouquayrol patented a breathing apparatus in 1860 for firefighting and use in mines, which used a demand regulator similar in principle to the demand valves later used for open-circuit scuba equipment and eventually lightweight demand helmets. In 1864, after collaboration with Auguste Denayrouze of the French navy, the apparatus was modified for underwater use, originally without a helmet, but later adapted for use with standard copper helmets.

In case of spillage it is recommended that a local fire department be called in advance prior to any attempt at cleaning. In case of fire it is recommended that the material be left to burn and the surrounding area be evacuated. If fire fighting is required it is recommended that a fully positive pressure self-contained breathing apparatus be used along with either foam or CO2 extinguishers.MSDS, chemcas.com.

This can be dangerous if medical emergencies arise during non- business hours. For example, a prisoner in CIW in 1997 went into labor over the weekend, when there was only one nurse on duty. The nurse strapped the woman into a gurney, but refused to help with her labor. When the baby was born not breathing, the nurse had to call paramedics, because she was unable to activate the breathing apparatus.

Delve and his deputy and successor, Leslie Leete, proposed control procedures that eventually became national policy, and also recommended the fitting of warning devices to breathing apparatus so that users were alerted when their oxygen supplies were running low. Having been awarded CBE in 1942, Delve was the first LFB chief to be knighted in office, in the 1962 Birthday Honours. After his 1962 retirement, he joined the board of Securicor.

For unexplained reasons, Czar Zosta and other Smogulans were able to withstand Earth's atmosphere without problems while Dr. Killemoff wears a breathing apparatus to survive. Dr. Killemoff, like most villains, also had a seemingly endless army of foot soldiers called Radiation Rangers. Other villains and heroes made their appearances on the show with equally ridiculous origins as the Crusaders. Few if any of these characters made more than one appearance.

These guidelines stress the use of 28% oxygen masks and caution the dangers of hyperoxia. Long-term use of supplemental oxygen improves survival in patients with COPD, but can lead to lung injury. An additional cause of hyperoxia is related to underwater diving with breathing apparatus. Underwater divers breath a mixture of gasses which must include oxygen, and the partial pressure of any given gas mixture will increase with depth.

With supporting equipment, the suit weighs about 50 pounds. Donning the suit takes between 30 and 45 minutes, with the assistance of a team of dressers. The suit's primary air supply comes through a hose connection to purified air; a self-contained breathing apparatus provides 8 to 10 minutes of escape air in case the primary supply is disrupted. A heart monitor around the wearer's chest checks for signs of distress.

In 2013, a friend encouraged Gómez to take up freediving, a sport that involves underwater diving without breathing apparatus. After some training, she managed to dive , and decided to take up the sport professionally. In her first year, Gómez attempted to break the Pan-American record for dynamic apnea, but became unconscious after swimming for . In 2014, she broke the dynamic apnea record by swimming for in Chiapas, Mexico.

U-1003 participated in two war patrol which resulted in no ships damaged or sunk. On 7 February 1944, during U-1003s trials, a crewman fell overboard and died while transferring to an outpost boat, near Hela on the Baltic Sea. U-1003 had Schnorchel underwater-breathing apparatus fitted out sometime before October 1944. U-1003 departed Bergen, Norway on 9 February, on her second, and last, war patrol.

U-1278 left on her first, and only, war patrol on 11 February 1945. At this time she was, and probably had been prior to, fitted with a Schnorchel underwater-breathing apparatus. Only 7 days into her patrol she was located by the British frigates and in the Norwegian Sea north- west of Bergen. She was sunk on 17 February 1945, by depth charges, killing all 48 of her crew.

Scuba diver of the late 1960s The history of scuba diving is closely linked with the history of scuba equipment. By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from the exhaled breathing gas, which is then recirculated, and more gas added to replenish the oxygen content. Closed circuit equipment was more easily adapted to scuba in the absence of reliable, portable, and economical high pressure gas storage vessels. By the mid-twentieth century, high pressure cylinders were available and two systems for scuba had emerged: open-circuit scuba where the diver's exhaled breath is vented directly into the water, and closed-circuit scuba where the carbon dioxide is removed from the diver's exhaled breath which has oxygen added and is recirculated.

By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from unused oxygen, which is then recirculated. Closed circuit equipment was more easily adapted to scuba in the absence of reliable, portable, and economical high pressure gas storage vessels. By the mid twentieth century, high pressure cylinders were available and two systems for scuba had emerged: open-circuit scuba where the diver's exhaled breath is vented directly into the water, and closed- circuit scuba where the carbon dioxide is removed from the diver's exhaled breath which has oxygen added and is recirculated. Oxygen rebreathers are severely depth-limited due to oxygen toxicity risk, which increases with depth, and the available systems for mixed gas rebreathers were fairly bulky and designed for use with diving helmets.

Two children, Jacques Mayol and Enzo Molinari, have grown up on the Greek island of Amorgos in the 1960s. Enzo challenges Jacques to collect a coin on the sea floor but Jacques refuses. Later, Jacques' father — who harvests shellfish from the seabed using a pump-supplied air hose and helmet — goes diving. His breathing apparatus and rope gets caught and punctured by rocks on the reef and weighed down by water, he drowns.

The diver opens the bailout valve on the helmet, bandmask or harness mounted bailout block. This opens the supply of breathing gas from the bailout cylinder carried by the diver to the demand valve of the breathing apparatus. The bailout gas volume carried by the diver is usually required to be sufficient to return to a place of safety where more gas is available, such as the surface, diving stage or wet or dry bell.

Instead, it's about the same adaptability that caused her to come forward with a mission, the qualities of resilience that it takes to survive now and in the future. In SUKIFU, a potted plant is housed inside a clear backpack (rucksack) hooked up to one tube to funnel fresh air into a face mask. It's a bold, abstract take on an oxygen tank. The transparent rucksack contains a plant, which connects to breathing apparatus.

Supermarine began development of the Type 300 in 1934, as a private venture following the unsuccessful Type 224 prototype.McLelland 2013, p. 24 Chief designer R. J. Mitchell and his team took the Type 224 as their starting point and continued to draw on their experience with the Schneider Trophy seaplanes. The Type 300 was considerably cleaned-up, with progressive refinements including retractable undercarriage, an enclosed cockpit, oxygen-breathing apparatus, and smaller and thinner wings.

Mycteroperca rosacea is considered to be an excellent food fish and is an important target species, among other grouper species, for large and small scale fisheries in the northern Gulf of California. It is also a popular quarry for game fishing. Poachers fish illegally for Leopard groupers using spears, hookah breathing apparatus, taking a significant number of fish. They can also be fished for in the surf in the early hours of the morning.

That limit was raised to a few years later. The result was a rapid increase in the number of rescue stations between 1911 and 1918. By 1918 there were ten Scheme "A" stations with permanent full-time rescue teams, and 36 Scheme "B" stations with officers and instructors who trained miners in rescue. Henry Fleuss developed a form of self-contained breathing apparatus that was used after an explosion at Seaham Colliery in 1881.

U-1023 carried 5 × torpedo tubes (4 located in the bow, 1 in the stern) and had one deck gun with 220 rounds. She could also carry 14 G7e torpedoes or 26 TMA mines and had a crew of 44–52 men. She was one of the U-boats that used the Schnorchel underwater breathing apparatus. After her redesignation as a front-line U-boat, U-1023 left port on her first and only patrol.

As the rescuers started to move into the affected area, the canaries carried were overcome almost at once. The afterdamp led to the deaths of a further two men, bringing the total deaths to 83. John Young Wallace (26) was part of a group travelling along the west materials road when he sat down, fell unconscious and died. All the group were using self-contained breathing apparatus with nose clips and mouthpieces.

Joy S. Reidenberg is an American comparative anatomist specializing in the vocal and breathing apparatus of mammals, particularly cetaceans (whales, including dolphins and porpoises). She is best known as the Comparative Anatomist in the TV science documentary series Inside Nature's Giants. In this series, she performed dissections of the animals to demonstrate anatomy, and explained how these adaptations function in live animals. Reidenberg became interested in animal science and art as a high school student.

Equipment problems are the trigger a large percentage of incidents, though equipment failures are less common. Procedural and human-machine interactions are a significant factor in rebreather incidents, and more common than in open circuit diving. In the European Union, breathing apparatus for underwater use is a category III product, meaning that failures are potentially lethal. The harmonised standard for diving rebreathers is EN 14143-2003, so rebreathers will be checked against that standard.

Then the refinisher will use a NIOSH-rated fresh-air supplied breathing apparatus to and spray suite and gloves to protect themselves from the chemicals being used in the process. They also provide assistance with the quality of the spraying. By using at least a 1200-cfm exhaust unit, the refinisher can see better and may limit the overspray and settling on the surface. primer (if used), is then applied, followed by a topcoat.

With the intense heat and thick smoke, internal fire fighting was effected on the first and second floors. Around this time, a small amount of fire was noted breaking through the first floor ceiling, which was addressed. This indicated serious fire in the attic floor above. At around 12:00 with the initial crews becoming exhausted, Divisional Officer Quinn requested the attendance of an emergency tender, for the additional breathing apparatus and fresh men.

They are also used in the filtration of air supplies for breathing apparatus, for example those used by scuba divers and firefighters. In such applications, air is supplied by an air compressor and is passed through a cartridge filter which, depending on the application, is filled with molecular sieve and/or activated carbon, finally being used to charge breathing air tanks. Such filtration can remove particulates and compressor exhaust products from the breathing air supply.

Combat divers do the majority of their work on inland waterways, either on the surface or beneath the water with breathing apparatus. They usually work close to shorelines and riverbanks because that is where the rest of the army will be conducting operations. At times the combat divers will work in salt water to support Army operations. In some circumstances, combat divers can be used to conduct reconnaissance in the face of enemy forces.

Mine Safety Appliances Co. has been manufacturing oxygen breathing apparatus for decades. Their "Chemox" chemical rebreather, primarily designed for use in mines, has been modified for use on Mount Everest in 1952 and 1986. They are stated to be simple in construction and operation. It is essentially a canister of potassium superoxide connected to one-way flow valves to an air bag and thence to the user, as in Rebreathers whose absorbent releases oxygen hereinabove.

Ralph McQuarrie incorporated samurai armor into his conceptual designs for Vader's costume in 1975. The original design of Darth Vader's costume did not originally include a helmet. The idea that Vader should wear a breathing apparatus was first proposed by concept artist Ralph McQuarrie during preproduction discussions for Star Wars with George Lucas in 1975. McQuarrie stated that Lucas's artistic direction was to portray a malevolent figure in a cape with samurai armor.

That morning, two kamikazes crashed into the aircraft carrier . Captain Porter brought Wilkes-Barre alongside Bunker Hill, placing her bow hard against the carrier's starboard quarter. Wilkes-Barre, along with three destroyers, aimed multiple fire hoses on the persistent fires, while 40 men, trapped astern in Bunker Hill scrambled to safety. Wilkes-Barre then transferred fire-fighting gear, rescue breathing apparatus and handy-billies to Bunker Hill, while taking the carrier's injured and dying.

A supplied-air respirator (SAR) or air-line respirator is a device used in places where the air may not be safe. It uses an air hose to supply air from outside the danger zone. It is similar to a self-contained breathing apparatus (SCBA), except that SCBA users carry their air with them in tanks, while SAR users get it from a stationary air supply attached to them by a hose.

At 23:45 a so-called "major call-out" took place from a fire station on the island, and four minutes later the first rescue team arrived on the scene. Six other fire crews were dispatched a short time afterwards. About 60 young people were rescued by firefighters with self-contained breathing apparatus, 40 of which were led down the staircase and 20 carried out through the windows. Others managed to escape on their own.

Divers are trained and assessed to the requirements of Australian Standard AS 2815.1 in no- decompression diving using self-contained underwater breathing apparatus (SCUBA) with the use of hand tools underwater to depths not exceeding 30 metres in accordance with AS/NZ 2299. This certification is suitable for work in scientific, fishing, marine archaeology, and engineering inspection applications. ADAS Part 1 is equivalent to the United Kingdom's HSE Part IV diver qualification.

It is a general purpose unit capable of carrying and pumping water, carrying rescue and cutting equipment to deal with road traffic accidents and other rescue operations, a large ladder (for example ) and several smaller ladders and roof ladders. The appliance also carries breathing apparatus, lighting, tools, trauma care packs, water rescue gear, lines (ropes), hoses, and possibly chemical protection suits and foam. The vehicle will be crewed by four to six firefighters.

At a demonstration by the Flinders pier, on Western Port Bay, south east of Melbourne, a diver passed out because he failed to purge the system of air. This failure to purge had resulted in a nitrogen build up. Eldred realized at this point that he needed to turn his efforts toward open circuit compressed air breathing apparatus. He was accompanied on this demonstration by Bob Wallace-Mitchell, who would become his distributor.

When the JCFD crews arrived at the tunnel portal, they also sent requests for more firefighters and for breathing equipment. The crews also worked on placing illumination inside the tunnel. The FDNY and JCFD called up 29 firefighting trucks of varying types and borrowed four more trucks with breathing apparatus from Consolidated Edison. In total there were about 63 emergency response vehicles (including police, medical units, Port Authority vehicles and supervisory vehicles).

In the US, many public safety divers are volunteers, but career law enforcement or fire rescue personnel also often take on these additional responsibilities as part of their occupation. Firefighters will find the diving equipment has similarities to the full face masks and breathing apparatus worn in smoke filled environments. Law enforcement personnel are also trained as public safety divers because of their training and experience in handling evidence and presenting evidence in court.

Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear. The risk of respiratory depression is especially high with potent fentanyl analogues such as alfentanil and brifentanil, and these drugs pose a significant risk of death if used outside of a hospital setting without an appropriate artificial breathing apparatus available.

Thomas Cheung Yiu-sing, 30, a senior officer attached to the Fire and Ambulance Services Academy in Tseung Kwan O, was part of the first breathing apparatus team to enter. The inferno suddenly intensified and Cheung was lost in the smoke. He was rescued and rushed to United Christian Hospital, where he was certified dead at 9:54 pm. Senior fireman Samuel Hui Chi-kit, 37, of Kwun Tong Fire Station, died in hospital on 23 June.

The time a system use to release the gas into a room is: Marine based installations: 8 seconds. Land based installations: 10 seconds. Even though the FS 49 C2 gas itself does not leave dangerous gases after being released into air, it is recommended to use a self-contained breathing apparatus when entering a room after a fire because in the process of extinguishing the fire, FS 49 C2 may release potentially harmful gases into the air.

Carbon dioxide or toxic gases, such as nitrogen oxides, accumulate from spoiling grain. They can cause asphyxiation in great enough concentrations without proper ventilation of the area. The dust can also sometimes have molds or spores that may be toxic or cause allergic reactions. There is at least one documented instance of a first responder requiring treatment as a result of such inhalation; rescuers are advised to wear at least dust masks or even self-contained breathing apparatus (SCBA).

Ken Boon (Elphick) and Harry Crawford (Daker) were both old-fashioned 'smokeys' (firemen) in the West Midlands Fire Service. In episode 1 Crawford takes early retirement and moves to Spain to open a bar, leaving Ken behind. In the same opening episode, Ken attends a house fire where a child is trapped upstairs. Realising he must act quickly he goes into the house without breathing apparatus, rescues the child but is severely injured by inhaling toxic smoke.

An initial dive in 1934 was unsuccessful and the first successful dive was the following year at Wookey Hole. They returned with improved equipment and succeeded in further exploration. Sheppard constructed his own dry suit, incorporating an oxygen rebreathing system, and used this to make the first successful cave dive in Swildon's Hole on 4 October 1936. For the initial 1934 dive Sheppard and colleague Francis Graham Balcombe constructed the first underwater breathing apparatus for cave diving.

Communicating through radio proved difficult, due to noise, the sheer volume of talk and possibly the concrete building structure. Instead, details of trapped residents were written on slips of paper and ferried by runners from the command unit to the bridgehead on the second floor. At the bridgehead, incoming firefighters were assigned flats to go to and briefed on whom they would need to rescue. They donned breathing apparatus and headed to the flat to search for its residents.

These are trucks which are designed for one purpose, like Rescue, or HAZMAT. Usually these are combined with another truck. (e.g. A pumper will be a combined Pumper/HAZMAT truck, or Pumper/Rescue) There is one statewide HAZMAT truck, which is based at Burnside CFS that responds to any HAZMAT incident in the state. It carries extra air cylinders for the Breathing Apparatus as well as gas tight suits, atmospheric monitoring equipment, and other specialised equipment.

While it was originally reported that 42 people had died, later investigation determined that 37 people succumbed and perished as smoke and fire overtook the bar. At its peak, the fire was fought by more than 50 firefighters. Five firefighters would be injured by smoke inhalation before the fire was declared out. At the time, the wearing of self-contained breathing apparatus (SCBA) was a relatively new practice and not as common among firefighters as it is today.

There was water fog equipment, but staff had not been trained in its use. The police made the decision to evacuate the station at 19:39, using the Victoria line escalators. A few minutes later the fire brigade arrived and several firemen went down to the escalator to assess the fire. They saw a fire about the size of a large cardboard box and planned to fight it with a water jet using men with breathing apparatus.

Investigators searched Paddock's room and found a "bulletproof vest" and breathing apparatus, neither of which were used by Paddock. There have been several changes in the official account and timeline of Paddock's shooting of hotel security guard Campos. Police officials described these adjustments as "minute changes" that are common in complex investigations. In their first statement about the incident, police officials inaccurately reported that Campos arrived on the scene after Paddock began firing into the crowd.

Since the 1930s divers have explored the extensive network of chambers developing breathing apparatus and novel techniques in the process. The full extent of the cave system is still unknown with approximately , including 25 chambers, having been explored. Part of the cave system opened as a show cave in 1927 following exploratory work by Herbert E. Balch. As a tourist attraction it has been owned by Madame Tussauds and, most recently, the circus owner Gerry Cottle.

The explosion occurred while workers were mixing certain chemicals to produce fireworks.Sivakasi fire unit mishap: 36 killed; PM, Sonia express grief (Hindustan Times, 6 September 2012) Some reports suggest the high ambient temperature in the factory, reported to be , may have been a factor. The initial explosion and a subsequent series of explosions could be heard more than two kilometres away. Fire fighter entry to the buildings was delayed by a lack of equipment, including breathing apparatus.

Pascal Bernabé is a French scuba diver who in 2005 laid claim to the world best for depth on a deep dive using self-contained breathing apparatus. Bernabé claimed to have reached a maximum depth of using trimix on 5 June 2005 near Propriano, Corsica. This was actually deeper than the official deepest scuba dive recognized by Guinness World Records at the time. That mark, set by Nuno Gomes in Dahab, Egypt, was of sea water.

In the film, Immortan Joe is the "ruler of the wasteland... He wears a clear, plastic carapace — chest armor — over oozing sores, his long, white hair flaring around a skeleton-smile mask he uses to hide a breathing apparatus." Several versions of his carapace, which display medals made from car and mobile phone parts, were created at Artisan Armours in the United Kingdom. Immortan Joe's third son, Scabrous Scrotus, was introduced in a spin- off video game.

U-1010 participated in one war patrol which resulted in no ships damaged or sunk. U-1010 had a Schnorchel underwater-breathing apparatus fitted out sometime before April 1945. On 14 May 1945, U-1010 surrendered at Loch Eriboll, Scotland and was later transferred to Lisahally. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1010 was one of 116 selected to take part in Operation Deadlight.

In the United States, U.S. Divers managed to keep "Aqualung" as a trademark. The acronym "SCUBA", or "Self Contained Underwater Breathing Apparatus", originated in the United States Navy, where it meant a frogman's rebreather. Scuba became the generic term for that type of open-circuit breathing set, and soon the acronym SCUBA became a noun -- "scuba" -- all in lower-case. "Scuba" was a trademark for a time – used by Healthways, now known as Scubapro - one of the competitors of U.S. Divers.

While there, Carrière, who had been an amateur scuba diver, applied to be a police diver. While working as a scuba diver with the RCMP Underwater Recovery Team in Cape Breton, searching a suspected drug-smuggling vessel, Carrière died during an underwater inspection. The Donia Portland was a large freighter, and Carrière was one of a team of five inspecting the vessel. He reported problems with his breathing apparatus, although his gauge showed he still had air in his tanks.

Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amounting to 80 terawatt hours consumption per year.

Sea sponge from Krapanj Krapanj has a rich history in deep sea diving, primarily in the harvesting and selling of sea sponges. Antun from Crete introduced Krapanj's inhabitants to diving and sea sponge gathering/processing over 300 years ago. For many years, diving for sponges had been the major income for Krapanj families, earning them the title of "Spužvari" (sponge vendors). By the middle of the 20th century the industry peaked with the inception of breathing apparatus and motorised boats.

Josh's outfit allows him to explore the lab, where he discovers several unconscious children, including Wendi, in stasis units; their hair shaved off and their eyes bandaged. One of the soldiers checks the ID on Josh's suit and, realizing he is an imposter, tears out his breathing apparatus, exposing Josh to the air. Josh flees back to the shelter, killing two of the soldiers on the way. After Josh returns, the soldiers weld the door shut from the outside, trapping everyone within.

A negative or zero pressure difference over the exhaust diaphragm will keep it closed. The exhaust diaphragm is exposed to the chamber pressure on one side, and exhaled gas pressure in the oro-nasal mask on the other side. The supply of gas for inhalation is through a demand valve which works on the same principles as a regular diving demand valve second stage. Like any other breathing apparatus, the dead space must be limited to minimise carbon dioxide buildup in the mask.

His next idea was to use a flexible rubber tube connecting the diver's mouth to an air intake on the surface supported by a float. Fernez registered a patent on this invention on 14 May 1912, which was granted on 22 July 1912.French patent FR 443802 "Appareil respiratoire pour séjourner sous l'eau ou dans des milieux irrespirables" (Breathing apparatus to stay under water or in environments unbreathable). Registered 14 May 1912, approved 22 July 1912, published 3 October 1912.

This is always updated to ensure any equipment or clothing needed is ready to be dispatched immediately to wherever it is needed. The workshops also maintain all of the operational equipment, from repairing the lengths of hoses to the breathing apparatus (BA) sets; this is carried out by the specialist "hose shop" also located on-site. Emergency repair is available 24/7 through an "on call" system where mechanics take turns to provide 24-hour service if an appliance or equipment becomes defective.

They entered the station wearing breathing apparatus and made numerous tests of the atmosphere before apparently concluding conditions were safe and removing their breathing devices. Observers speculate that the flight had a specific objective and was not meant to be a long-duration mission. In any case, fuel for the station to maneuver was too depleted to attempt a long mission. The crew continued the research started by the Soyuz 21 crew, performed Earth resources work, biological and materials experiments.

Development of breathing systems, thermal protection, and decompression procedures for SEAL Delivery Vehicles and the Advanced SEAL Delivery System is ongoing. In 2011, divers completed a 1,000 fsw saturation dive to evaluate the new Navy's Saturation Fly-Away Diving System (SAT FADS). The SAT FADS was designed in 2006 as a portable replacement of two decommissioned Pigeon-class submarine rescue vessels. Evaluation and testing of new breathing apparatus and application of other technologies for diving is key to their mission.

Gomes used self-contained underwater breathing apparatus to dive to a depth of in the sea. The dive was done in the Red Sea off the coast of Egypt near Dahab in June 2005. Gomes' total dive time was 12 hours and 20 minutes; the descent took only 14 minutes. He is one of only three men verified by Guinness World Records to have dived with scuba equipment (using trimix) below ; the other two divers are the late John Bennett and Ahmed Gabr.

U-1278 left on her first, and only, war patrol on 29 January 1945. At this time she was, and probably had been prior to, fitted with a Schnorchel underwater-breathing apparatus. Thirty days into her patrol she was spotted and attacked by the British frigates , , the British sloop and a US Liberator aircraft from VPB-112 in the English Channel east of the Scilly Isles. She was sunk on 27 February 1945, by depth charges, killing all 48 of her crew.

Pressure regulators are used with Diving cylinders for Scuba diving. The tank may contain pressures in excess of , which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled regulator provides a flow of breathing gas at the ambient pressure (which varies by depth in the water). Pressure reducing regulators are also use to supply breathing gas to surface-supplied divers, and people who use self-contained breathing apparatus for rescue and hazmat work on land.

Another use is for communication when speech is masked by background noise or distorted by self-contained breathing apparatus. A further practical use is where a need exists for silent communication, such as when privacy is required in a public place, or hands- free data silent transmission is needed during a military or security operation.Hueber T, Benaroya E-L, Chollet G, Denby B, Dreyfus G, Stone M.

Initially the medical spectrophotometer had a mask-style attachment, into which the patient breathed. This was later modified to use a nasal catheter because many polio patients could not use the mouth-breathing apparatus. Eventually the Polio Foundation began to use Liston's Model 16 CO2 analyzer to monitor Iron Lung machines, cutting in half both the time that patients spent in the machines and the death rate of Iron Lung machine users. Liston developed an industrial analyzer in response to a request from Dupont.

They are equipped with a tractor-trailer that contains a large air compressor, a large cache of self-contained breathing apparatus (SCBA) and extra SCBA cylinders. Their primary objective is to provide logistical support to other responding teams and authorities responding to emergencies. Capabilities Their capabilities include providing breathable air and refill cylinders, along with a cascade system to other responding units. Their generators allow for them to provide power and electrical backup to other responding authorities; along with tower lighting and long-range communication abilities.

In underwater diving, the breathing apparatus is considered to be life support equipment, and a saturation diving system is considered a life-support system – the personnel who are responsible for operating it are called life support technicians. The concept can also be extended to submarines, crewed submersibles and atmospheric diving suits, where the breathing gas requires treatment to remain respirable, and the occupants are isolated from the outside ambient pressure and temperature. Medical life-support systems include heart-lung machines, medical ventilators and dialysis equipment.

To qualify as Level A protection, an intrinsically safe two- way radio is also worn inside the suit, often incorporating voice-operated microphones and an earpiece speaker for monitoring the operations channel. ;Level B: Level B protection requires a garment (including SCBA) that provides protection against splashes from a hazardous chemical. Since the breathing apparatus is sometimes worn on the outside of the garment, Level B protection is not vapor-protective. Level B suits can also be fully encapsulating, which helps prevent the SCBA from becoming contaminated.
|
|
Such suits (level A in the US) are gas or vapor-tight, providing total encapsulation and the highest level of protection against direct and airborne chemical contact. They are typically worn with a self-contained breathing apparatus (SCBA) enclosed within the suit. These suits are typically constructed of several layers and, being airtight, include a release valve so the suit does not overinflate from air exhaled by the SCBA. The release valve does retain some air to keep some positive pressure ("overpressure") inside the suit.

PAPRs are not effective during firefighting, in an oxygen-deficient atmosphere, or in an unknown atmosphere; in these situations a self-contained breathing apparatus or supplied-air respirator is recommended instead. PAPRs have the advantage of eliminating breathing resistance caused by unpowered negative-pressure respirators such as N95 masks. This makes them usable by persons who are medically disqualified from negative-pressure respirators. Loose-fitting PAPRs may also be selected for people who cannot pass a fit test due to facial hair or other reasons.

Besides tissue rupture, the overpressure may cause ingress of gases into the tissues and further afield through the circulatory system. This pulmonary barotrauma (PBt) of ascent is also known as pulmonary over-inflation syndrome (POIS), lung over-pressure injury (LOP) and burst lung. Consequent injuries may include arterial gas embolism, pneumothorax, mediastinal, interstitial and subcutaneous emphysemas, not usually all at the same time. Breathing gas at depth from underwater breathing apparatus results in the lungs containing gas at a higher pressure than atmospheric pressure.
|
|
Factors which influence the work of breathing of an underwater breathing apparatus include density and viscosity of the gas, flow rates, cracking pressure (the pressure differential required to open the demand valve), and back pressure over exhaust valves. Work of breathing of a diver has a physiological component as well as the equipment component. for a given breathing gas mixture, the density will increase with an increase in depth. A higher gas density requires more effort to accelerate the gas in the transition between inhalation and exhalation.
|
|
Divers ascending using breathing apparatus typically ascend at slower ascent rates to avoid decompression sickness, and the depth at which consciousness is lost tends to follow the oxygen partial pressure of the breathing gas. The partial pressure of oxygen in the air in the lungs controls the oxygen loading of blood. A critical pO2 of in the lungs will sustain consciousness when breathing is resumed after a breath-hold dive. This is about 4% oxygen in the lungs and 45% oxygen saturation of the arterial blood.

Davis breathing apparatus tested at the submarine escape test tank at HMS Dolphin, Gosport, 14 December 1942 After the sinking of the A1 submarine in 1904, lifting eyes were fitted to British submarines and in 1908 air-locks and escape helmets were provided. The RN experimented with various types of escape apparatus, but it was not until 1924 that the "Davis Submerged Escape Apparatus" was developed for crew members. The USN used the similar "Momsen Lung". The French used "Joubert's apparatus" and the Germans used "Draeger's apparatus".

The different respirator designs showed large variations in protectiveness, partially attributable to the comfort of the respirator design: the more comfortable masks were adjusted more tightly and were therefore more effective. A 1979 study of the effectiveness of self-contained breathing apparatus (SCBA) in protecting firefighters against inhalation of carbon monoxide showed that intermittent usage of these respirators made them ineffective. Even continuous usage of SCBAs did not provide complete protection. This SCBA design had an air supply into the mask that supplied air "on-demand" (i.e.

She also worked at Derbyshire Fire and Rescue Service's training centre, as a Breathing Apparatus Instructor and a Group Manager for learning and development. She is a fully qualified Fire Protection Officer. Johnson is a member of the National Executive Committee of Women in the Fire Service (UK), a not-for-profit organisation that aims to inspire, enable and develop women with the Service. In the early 1990s, she attended her first Women in the Fire Service UK conference and the Fire Brigades Union women's school.

In 1906 the Lancashire and Cheshire Coal Owners Association formed a committee which decided to provide a mines rescue station in Lovers Lane Atherton. The first rescuers were provided with Siebe Gorman Proto breathing apparatus which was selected by competition. A team from the rescue station was tasked with training rescue teams from each colliery, and provided emergency assistance to collieries throughout the Lancashire Coalfield. Teams from the rescue station attended disasters at the Maypole Colliery in Abram in 1908 and the Pretoria Pit Disaster in 1910.

Firefighting equipment in the United States is based on lightweight materials developed for the U.S. Space Program. NASA and the National Bureau of Standards created a lightweight breathing system including face mask, frame, harness, and air bottle, using an aluminum composite material developed by NASA for use on rocket casings. The broadest fire-related technology transfer is the breathing apparatus for protection from smoke inhalation injury. Additionally, NASA's inductorless electronic circuit technology led to lower-cost, more rugged, short-range two-way radio now used by firefighters.

A contemporary account suggested that it might be characterized as "government pork". The facilities for the Bureau of Mines were described as the "best ... hitherto given to this organization". In addition to offices, a lecture hall, and electrical connections for a "motion-picture machine", these facilities included a smoke room, equipped with an exhaust fan, which was used in training miners in the use of breathing apparatus for mine rescues. A similar combination post office and mine-rescue station was later built in Norton, Virginia.

John Bennett (1959–2004) was a British scuba diver who set a world record by becoming the first person to deep dive below a depth of on self-contained breathing apparatus on 6 November 2001. In the early 2000s, Bennett and Ron Loos made the first dives to the wreck site in Manila Bay. In 2001, he located the wreck of the Imperial Japanese Navy dreadnought Yamashiro through sound scans, but could not confirm it before his death. Confirmation was not made until 2017.

Invented in 1916 by Riichi Watanabi and the blacksmith Kinzo Ohgushi, and used with either surface supplied air or a 150 bar steel scuba cylinder holding 1000 litres free air, the valve supplied air to a mask over the diver's nose and eyes and the demand valve was operated by the diver's teeth. Gas flow rate was proportional to bite force. The breathing apparatus was used successfully for fishing and salvage work and by the military Japanese Underwater Unit until the end of the Pacific War.

The helmet contained integral goggles with infrared sighting, telescopic lenses, magnetic resonance scanning, and a camera attachment. It also includes a breathing apparatus, voice scrambler, two-way radio communications device, parabolic sound enhancer, and a cybernetic link to armor systems. He carried a pair of truncheons, Escrima sticks which he called his "Battle Staves" which attached to special slots in the back of the Mark I armor, and an armored high tech fiberglass skateboard with a retractable razor-sharp blade. The board also hooked onto the back of his armor.

A SCSR is usually a closed-circuit breathing apparatus with a chemical oxygen generator or a compressed oxygen cylinder and a carbon dioxide absorber. SCSRs are most commonly used in some coal mines, are intended for one person, and usually supply at least one hour of oxygen. SCSRs are intended to facilitate escape from mines after a fire or explosion. They are also used by people working with machinery on the surface of a mine or pit, in case they become covered by such materials as coal or sand.

Siebe Gorman Aerorlox oxygen rebreather Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe , a German-born British engineer chiefly known for his contributions to diving equipment. Siebe plc started in the 1970s as a continuation of Siebe Gorman when Siebe Gorman started to take over other firms, to mean the new conglomerate to distinguish it from Siebe Gorman's original breathing apparatus and diving gear core business.

A chemical accident in Tri-Klops' lab mutated Odiphus into Stinkor and gave him his horrible stench. Stinkor is not immune to his own stench and must wear an oxygen mask to breathe properly. Stinkor eventually incorporated into his breathing apparatus a way to control his stench into focused blasts and teamed up with Skeletor against He-Man and the other Masters of the Universe. As it turns out as difficult as Stinkor is to be around, Skeletor eventually holds him in relatively high favor as a minion who has proved himself agreeably useful.

Full-face masks intended for use with scuba may provide a method of switching to atmospheric air when above the surface, to save breathing gas. Rebreather systems often incorporate a dive/surface valve in the mouthpiece which may provide an opening to the ambient environment when the loop is isolated. Some other full- face masks allow the demand valve to be unplugged on the surface, or provide a "snorkel valve" port which can be opened to allow atmospheric air to enter. The small saving on breathing gas is unimportant with surface-supplied breathing apparatus.

Exhibition 1993 The fire and explosions hampered rescue and police efforts and caused several million dollars worth of damage to the centre, impacting on the building's owner—AMP Limited—and its tenants. Two local radios stations and numerous employees were inside the centre at the time requiring tactical police to assists in their evacuation. After several explosions, which resulted in the street being showered with broken glass, Australian Federal Police Special Operations Team wearing breathing apparatus entered the centre, eventually locating the deceased gunman with shotgun wounds to his stomach and his body badly burned.

However, during his second encounter, an armada of Dragon Ships sent by the Xotli priests overcome Conan and his crew. All the pirates are knocked unconscious by sleeping gas and taken ashore, to be eventually sacrificed to Xotli with their hearts torn out of their chests. Conan alone manages to escape, stealing a breathing apparatus from one of his attackers and diving into the sea. After some underwater adventures (he is threatened by a giant octopus and a shark; the two start fighting each other and forget about him), Conan comes ashore.

Scania P320 Type 4 Heavy Pumper of the Wodonga CFA Pumpers are equipped with a large pump capable of pumping thousands of litres of water per minute, some up to 4000 litres per minute. Pumpers are generally used in an urban environment to fight structure fires, as they require a reticulated or static water supply (e.g.: a dam) to operate. Pumpers are also equipped with an extensive inventory of operational equipment including hoses, nozzles, ladders, breathing apparatus, chemical protection suits and other fire fighting gear, stowed in lockers on board the pumper.

She is taken to a circular operating table and tied down whilst a breathing apparatus is attached to her face, followed by a thin needle drill moving towards her. She resists throughout, comparing them to the military who created her, commenting "I guess I haven't fallen past terror after all...". On the Euphrates, the ship's commanding officer complains about the 'android survivors' of the Typhoon and the super soldiers' request to be transferred to a high security asteroid facility. The CO has been uneasy since they arrived and has them restricted to the science pod.

Fire tenders are generally equipped with associated fire station equipment including required number of breathing apparatus, first aid kits, telescopic ladders, heat-resisting fiberglass blankets, overall suits, electrically insulated rubber hand gloves, fireman's axes with insulated handle, fireman's helmets made of fiberglass, leather belt and pouch for axe, etc. Often the technique of pump-and-roll is used where the vehicle drives with the pump engaged while a firefighter uses a hose to spray water on the fire. This technique allows a team of two to flank the perimeter of a fire.

In doing so he greatly prejudiced his chance of escape. He was not a submarine officer and was not familiar with the use of the breathing apparatus or the lay-out inside a submarine. In spite of these handicaps and the pitch darkness his only thoughts were for those within the submarine; he had no hesitation in re- entering the SIDON and he succeeded in helping two more men to escape before the submarine sank. Surgeon Lieutenant Rhodes' gallant and selfless act in helping to save the lives of others cost him his own life.

After his work for the Royal Commission, Applegarth became a commercial traveller for a French firm selling Henry Fleuss's underwater breathing apparatus. He took out the English patent for the Yablochkov candle and made a fairly successful business out of it based in Epsom. When his old friend Howell lost his seat in Parliament in 1895 and fell ill, Applegarth and the TUC raised a £1650 testimonial to buy him an annuity. In 1898 he became a poultry farmer in Bexley, where he introduced a new breed of French hen.

Numerous changes occurred in the department in the 1970s, with several improving the health and safety of firefighters. On September 20, 1970, the city hired its first black firefighter, Bobby Glenn, who later retired after serving the department for over 21 years. The city purchased its first set of MSA SCBA breathing apparatus, replacing old canister masks that were rarely worn. Also, firefighters stopped riding to emergencies on the tailboard of fire apparatus and were contained in cabs of apparatus, protecting them from various hazards including falling off the apparatus.

U-1053 was used as a Training ship in the 5th U-boat Flotilla from 12 February 1944 to 31 October 1944 before serving in the 11th U-boat Flotilla for active service on 1 November 1944. The submarine was fitted with a Schnorchel underwater-breathing apparatus in March 1944. During her active service, U-1053 made 1 patrol. She left Horten on 7 November 1944 and patrolled a large part of the Atlantic Ocean before arriving at Stavanger on 21 January 1945 after a patrol of 76 days.

His first important one, patented in 1990, was the Gamow bag enabling mountain climbers to avoid altitude sickness by raising the surrounding pressure. Sir Edmund Hillary, the first expedition leader to summit Mount Everest, wrote him in congratulation. Another was the Shallow Underwater Breathing Apparatus ("SUBA"), a pressurized snorkel system permitting swimmers to breathe easily as deep as ten feet under water. Igor Gamow continues to work in bionics, on an orthopedic knee brace that stores energy within a spring from the hamstring and redirects it to the quadriceps.

2 frogmen with Siebe Gorman SCBA (or similar) 1950's-type rebreathers British "frogman's" sets used the same shape of counterlung as the CDBA but different cylinders. One type was the "Swimmer Canoeists Breathing Apparatus" (SCBA), which had oxygen cylinders on the back, vertically for better streamlining in swimming, the oxygen connections thinner, and no cylinders on the front, leaving the diver's lower front uncluttered for climbing in and out of small boats. The SCBA gave 90 minutes dive duration with no reserve. In mixture (nitrox or heliox) mode it was called SCMBA.

Breathing under pressure involves several effects. Metabolically inactive gases are absorbed by the tissues and may have narcotic or other undesirable effects, and must be released slowly to avoid the formation of bubbles during decompression. Metabolically active gases have a greater effect in proportion to their concentration, which is proportional to their partial pressure, which for contaminants is increased in proportion to absolute ambient pressure. Work of breathing is increased by increased density of the breathing gas, artifacts of the breathing apparatus, and hydrostatic pressure variations due to posture in the water.

Most deaths in coal mines were caused by the poisonous gases caused by explosions, particularly afterdamp or carbon monoxide. Survivors of explosions were rare and most apparatus taken underground was used to fight fires or recover bodies. Early breathing apparatus derived from under-sea diving was developed and a crude nose and mouthpiece and breathing tubes was tried in France before 1800. Gas masks of various types were tried in the early-19th century: some had chemical filters, others goat skin reservoirs or metal canisters, but none eliminated carbon dioxide rendering them of limited use.

In December 1998, Houston was off the coast of southern California during a training exercise when the common discharge flex coupling for the boat's R-12 units ruptured. R-12 is a refrigerant that is used in air-conditioning and refrigeration units. The quick actions of the crew allowed the R-12 to be ventilated overboard while the crew were in emergency air-breathing apparatus (EABs) that protected them from the asphyxiating effects of the gas. A quick stores off-load also saved the perishable foods in the refrigeration compartments.

Gands are insectoids who evolved on the planet Gand. There are two main sub-species of Gands: those with lungs, which are very rare, and those without. Gands with lungs are adapted to Gand's ammonia-rich atmosphere, but they are poisoned by oxygen and must use a special breathing apparatus if they want to leave Gand. Gands without lungs have special regeneration properties, demonstrated by their ability to recover quickly from injuries and even re-grow lost limbs (As shown by Ooryl Qrygg in the X-wing series by Michael Stackpole).

Commentators have noted this goes against Weaver's and James Cameron's statements about reading Blomkamp's script for the film, although it's possible Weaver and Cameron were referring to the pitch document. On May 1, 2017, Ridley Scott confirmed that the fifth film is not happening. An alternate ending for The Predator displaying a Weyland-Yutani Corp pod containing Ripley (played by Breanna Watkins) wearing a Weyland-Yutani breathing apparatus shaped like an Alien Facehugger was yet one among several references intended to further connect the Predator films to the Alien films.

Swimfin from Aqua Lung Diving regulator Aqua Lung Legend (2010) Diving cylinder for 200 Bar with DIN cylinder valve from Aqua Lung Aqua Lung International (formerly La Spirotechnique) is a large and well-known firm which makes scuba and other self-contained breathing apparatus, and other diving equipment. It produced the Aqua-Lung line of regulators, like the CG45 (1945) and the Mistral (1955), among others. Until 2016, the company was a division of Air Liquide since its foundation in 1946. The company was sold to Montagu Private Equity in 2016.

The appropriate tests depend on the condition of the unit and the specifics of the case. As a general rule the first items are to download the logs from dive computers and breathing apparatus following the manufacturer's specifications. The assembled rebreather's exterior is checked and photographed, and the gas content of the counterlung is sampled and analyzed. Although there are many possibilities for the counterlung gas to mix with the surroundings, a finding of a low oxygen content may indicate hypoxia if there is no evidence of an alternative cause of low oxygen levels.

US Air Force firefighters in suits with an outer aluminized shell go through a decontamination line during an emergency management exercise. A hazmat suit (hazardous materials suit) is a piece of personal protective equipment that consists of an impermeable whole-body garment worn as protection against hazardous materials. Such suits are often combined with self-contained breathing apparatus (SCBA) to ensure a supply of breathable air. Hazmat suits are used by firefighters, emergency medical technicians, paramedics, researchers, personnel responding to toxic spills, specialists cleaning up contaminated facilities, and workers in toxic environments.

After the first explosion on 19 December, re-entry to the mine was carried out by mine rescue teams wearing breathing apparatus, until it was established that it was safe for the AWRE men to return. They found that the stemming in the crosscut had failed to contain the blast, which had destroyed the cables and control equipment for the second charge. This was repaired and the second explosion scheduled for 15 January 1960. The evening before it was due, a group of Greenside men were finishing off some sandbagging.

Abe Sapien is one of the characters appearing in two straight- to-DVD Hellboy Animated films, Hellboy: Sword of Storms and Hellboy: Blood and Iron, in which he is voiced by Doug Jones. This version of the character, although similar to the movie Sapien, is much more like his comic book counterpart, showing signs of neither the psychic abilities nor breathing apparatus. However, he is far faster, more agile and stronger than humans in the films, allowing him to fight giant creatures that only Hellboy is thought to be strong enough to fight.

The breathing gas supply is usually referred to separately. There is no generic term for the combination of suit and breathing apparatus alone. It is generally referred to as diving equipment or dive gear along with any other equipment necessary for the dive. Diving suits can be divided into two classes: "soft" or ambient pressure diving suits – examples are wetsuits, dry suits, semi-dry suits and dive skins – and "hard" or atmospheric pressure diving suits, armored suits that keep the diver at atmospheric pressure at any depth within the operating range of the suit.

If the barrel is not completely depressurized, the pig can be ejected from the barrel and operators have been severely injured when standing in front of an open pig door. A pig was once accidentally shot out of the end of a pipeline without a proper pig receiver and went through the side of a house 500 feet away. When the product is sour, the barrel should be evacuated to a flare system where the sour gas is burnt. Operators should wear a self-contained breathing apparatus when working on sour systems.

As the importance of pre-hospital care skyrocketed in the service, the Special Casualty Access Team (SCAT) was formed in 1986. This team of elite paramedics brought intensive care to patients in the most extreme of situations, ranging from cliff falls to building collapses. SCAT Paramedics were trained in a range of skills including climbing, winching, breathing apparatus, CBRNE, caving, canyoning, USAR, bushcraft, four wheel driving and wilderness survival. A major step forward for the service came in 1991, when every ambulance in NSW was able to be equipped with a defibrillator.

As an avid climber, in 2006 Lewsey was given the summer off from international rugby and spent time climbing in the Himalayas reaching the base camp of K2. He did not inform his club of the expedition as he was sure they would object. In 2010 Lewsey and his friend Keith Reesby were unsuccessful in their attempt to climb to the summit of Mount Everest via the difficult North Col route. Both climbers were within 500 feet of the summit when breathing apparatus failure caused them to abandon the ascent.

This is a form of back-pressure regulator. The supply of gas for inhalation is through a demand valve which works on the same principles as a regular diving demand valve second stage. Like any other breathing apparatus, the dead space must be limited to minimise carbon dioxide buildup in the mask. BIBS regulators for hyperbaric chambers have a two-stage system at the diver similar to reclaim helmets, though for this application the outlet regulator dumps the exhaled gas through an outlet hose to the atmosphere outside the chamber.

A raft used for snuba showing the air cylinder and hoses Snuba is form of surface-supplied diving that uses an underwater breathing system developed by Snuba International. The origin of the word "Snuba" may be a portmanteau of "snorkel" and "scuba", as it bridges the gap between the two. Alternatively, some have identified the term as an acronym for "Surface Nexus Underwater Breathing Apparatus", though this may have been ascribed retroactively to fit the portmanteau. The swimmer uses swimfins, a diving mask, weights, and diving regulator as in scuba diving.

Breathing under pressure involves several effects. Metabolically inactive gases are absorbed by the tissues and may have narcotic or other undesirable effects, and must be released slowly to avoid the formation of bubbles during decompression. Metabolically active gases have a greater effect in proportion to their concentration, which is proportional to their partial pressure, which for contaminants is increased in proportion to absolute ambient pressure. Work of breathing is increased by increased density of the breathing gas, artifacts of the breathing apparatus, and hydrostatic pressure variations due to posture in the water.

At the time in the London Fire Brigade and other UK authorities, the wearing of BA was restricted to a number of trained and generally more senior fire-fighters. A number of open circuit compressed air breathing apparatus sets were also used, the Siebe Gorman Airmaster carried on some pumping appliances. These represent the type used in the UK fire service and others worldwide today. The set comprises a large cylinder charged with compressed air, linked to a demand valve combined into the face mask, secured with straps around the head.

In the decade following World War II, Lambertsen et al. made further discoveries on the effects of breathing oxygen under pressure and methods of prevention. Their work on intermittent exposures for extension of oxygen tolerance and on a model for prediction of pulmonary oxygen toxicity based on pulmonary function are key documents in the development of standard operating procedures when breathing increased pressures of oxygen. Lambertsen's work showing the effect of carbon dioxide in decreasing time to onset of central nervous system symptoms has influenced work from current exposure guidelines to future breathing apparatus design.

This includes the correct function and availability of essential medical gases and associated ventilatory equipment and breathing apparatus. The AP is also responsible for ensuring that critical controlled and emergency medications are accessible prior to the induction of anaesthesia. They are also routinely charged as being custodians of the controlled drugs/scheduled medications held within their dedicated theatre, being assigned security keys which remain on their person throughout the day. The AP is responsible for conducting a pre- operative assessment of the patient prior to their admission to the department.

They hold their breath during terrestrial locomotion and breathe in bouts as they rest. North American box turtles breathe continuously during locomotion, and the ventilation cycle is not coordinated with the limb movements. This is because they use their abdominal muscles to breathe during locomotion. The last species to have been studied is the red- eared slider, which also breathes during locomotion, but takes smaller breaths during locomotion than during small pauses between locomotor bouts, indicating that there may be mechanical interference between the limb movements and the breathing apparatus.

|
This type includes airline respirators and self-contained breathing apparatus (SCBA). In work environments, respirators are relied upon when adequate ventilation is not available or other engineering control systems are not feasible or inadequate. In the United Kingdom, an organization that has extensive expertise in respiratory protective equipment is the Institute of Occupational Medicine. This expertise has been built on a long-standing and varied research programme that has included the setting of workplace protection factors to the assessment of efficacy of masks available through high street retail outlets.

Breathing apparatus must allow the diver to breathe with minimum added work of breathing, and minimise additional dead space. It should be comfortable to wear, and not cause stress injury or allergic reactions to component materials. It must be reliable and should not require constant attention or adjustment during a dive, and if possible performance should degrade gradually in the event of malfunctions, allowing time for corrective action to be taken with minimum risk. Holding the scuba mouthpiece between the teeth can case jaw fatigue on a long dive.

Divers are trained and assessed to the requirements of Australian Standard AS 2815.2 in diving using surface-supplied underwater breathing apparatus (SSBA) to depths not exceeding 30 metres in conditions where surface compression chambers are not required to be present on site by AS/NZ 2299. This certification is the minimum level for work as a construction diver in Australia. Training may include the use of powered tools, cutting and welding, underwater construction and underwater explosives. ADAS Part 2 is equivalent to the United Kingdom's HSE Part III diver qualification.

To combat some of these risks, firefighters carry self-contained breathing apparatus. The first step in a firefighting operation is reconnaissance to search for the origin of the fire and to identify the specific risks. Fires can be extinguished by water, fuel or oxidant removal, or chemical flame inhibition; though, because fires are classified depending on the elements involved, such as grease, paper, electrical, etcetera, a specific type of fire extinguisher may be required. The classification is based on the type of fires that the extinguisher is more suitable for.
|
|
In addition, tools like axes, flashlights, fire extinguishers, a self-contained breathing apparatus, a first aid kit, adapters, and a hydrant wrench may be required. Some tenders carry also foaming agents, and extinguishing powders or gases. Examples of specialised water tenders include airport crash tenders and wildland water tenders. An Australian Water Tender can range from a standard fire engine, with a larger- than-usual capacity (usually called a tanker), to a Water Tender equipped with specialty equipment such as fixed monitors and long-throw foam nozzles (usually called a Bulk Water Carrier).

The peak body is the Fin Swimming Commission (operating as Ozfin Inc.) of the Australian Underwater Federation (AUF). There are state commissions in New South Wales, Tasmania and Victoria. Ozfin's operations are concerned with building participation levels, improvement of competition standards, offering national and international competition within Australia, developing national teams for international competition, supporting domestic competition via the provision of technical and promotional support, and the accreditation of coaches and officials. As of September 2013, Ozfin only offers swimming pool races for surface swimming, bi-fins, apnoea finswimming and immersion finswimming with breathing apparatus.

Pressure and humidity also decline, and aircrew are exposed to radiation, vibration and acceleration forces (the latter are also known as "g" forces). Aircraft life support systems such as oxygen, heat and pressurization are the first line of defense against most of the hostile aerospace environment. Higher performance aircraft provide more sophisticated life support equipment, such as "G-suits" to help the body resist the adverse effects of acceleration, along with pressure breathing apparatus, or ejection seats or other escape equipment. Every factor contributing to a safe flight has a failure rate.

U-1005 participated in two war patrol which resulted in no ships damaged or sunk. U-1005 had Schnorchel underwater-breathing apparatus fitted out sometime before February 1945. On 14 May 1945, U-1005 surrendered at Bergen, Norway and was transferred to Loch Ryan, Scotland on 2 June 1945, where she would wait nearly six months for her final fate. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1005 was one of 116 selected to take part in Operation Deadlight.

U-998 had been fitted out in May 1944, with a Schnorchel underwater-breathing apparatus. Departing Kiel on 12 June 1944, U-998 left on her first, and only, war patrol. Five days into her patrol U-998 was located on 16 June 1944, west of Bergen, by two Norwegian Mosquito FB Mk XVIII aircraft from 333 Sqdn RAF, piloted by Erling U. Johansen and Lauritz Humlen. They were able to hit the boat with 57mm cannon fire and depth charges which caused severe damage to U-998.

At 5:45 pm on 20 November 1931, firedamp was ignited in the North East Colliery Face of the mine which caused roof falls preventing the men from reaching the shaft and the pit-head. After the explosion there was another inrush of gas which starved oxygen from the air. As news of the disaster spread, a crowd of over 2,000 people gather at the pit head to wait for news. Four men went down the pit wearing breathing apparatus and had to carry the injured over to get them to safety.

This marked the first time the missiles had been used against a tactical objective and the only time they were fired on a German target. The 11 missiles launched killed six Americans and a number of German citizens in nearby towns, but none landed closer than some from the bridge. When the Germans sent a squad of seven naval demolition swimmers wearing Italian underwater breathing apparatus, the Americans were ready. For the first time in combat, they had deployed the top-secret Canal Defence Lights which successfully detected the frogmen in the dark, who were all killed or captured.

Scuba diving is diving with a self-contained underwater breathing apparatus, which is completely independent of surface supply. Scuba gives the diver mobility and horizontal range far beyond the reach of an umbilical hose attached to surface-supplied diving equipment (SSDE). Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a diving regulator.

He is equipped with a breathing apparatus fueled by oxygen cubes (as Venus' atmosphere cannot sustain human life) and has a leather protective suit, as well as a "flame pistol" to use against lizardmen. While on a routine mission, the narrator encounters a bizarre structure: a maze whose walls are completely invisible, inside of which is a crystal of unusually large size. The prize is held by a dead prospector. The protagonist, feeling confident he can map out the maze, makes his way to the center after collecting the crystal in order to explore the structure.

Scuba diver with bifocal lenses in half mask There are two basic categories of diving mask: The half mask covers the eyes and nose, and the full face mask covers eyes, nose and mouth, and therefore includes a part of the breathing apparatus. The half mask is described here. Diving masks may have a single, durable, tempered glass faceplate, or two lenses in front of the eyes. These may be supported by a relatively rigid plastic or metal frame, or they may be permanently bonded to the rim of the skirt, in a construction known as "frameless".

Many other fire-safety improvements also stemmed from this incident. Due to the first bomb blast, which killed nearly all of the trained firefighters on the ship, the remaining crew, who had no formal firefighting training, were forced to improvise. All current Navy recruits receive week-long training in compartment identification, fixed and portable extinguishers, battle dress, self-contained breathing apparatus and emergency escape breathing devices. Recruits are tested on their knowledge and skills by having to use portable extinguishers and charged hoses to fight fires, as well as demonstrating the ability to egress from compartments that are heated and filled with smoke.

Gagnan miniaturized and adapted it to gas generators in response to a fuel shortage, which was a consequence of German requisitioning. Gagnan's boss, Henri Melchior, knew that his son-in- law Jacques-Yves Cousteau was looking for an automatic demand regulator to increase the useful endurance of the underwater breathing apparatus invented by Commander Yves le Prieur,Jacques-Yves Cousteau with Frédéric Dumas, The Silent World (London: Hamish Hamilton, 1953). so he introduced Cousteau to Gagnan in December 1942. On Cousteau's initiative, the Gagnan regulator was modified for use in diving. Cousteau and Gagnan were issued a patent some weeks later in 1943.

It houses the Criminal Justice program, the Fire Science/EMS program, the Suburban Law Enforcement Academy and the COD police department. The center has an Immersive Interior Training Lab, forensics and cybercrimes labs, an auditorium that doubles as a mock courtroom, a self-contained breathing apparatus lab, and a debriefing room.[61] The center also includes a Memorial to the September 11 attacks in its lobby with the centerpiece being a steel beam recovered from the towers.[62] McAninch Arts Center The McAninch Arts Center was built in 1986, and is named after the college's second president.

Some variants used rebreather systems to extend the use of gas supplies carried by the diver, and were effectively self-contained underwater breathing apparatus, and others were suitable for use with helium based breathing gases for deeper work. Divers could be deployed directly by lowering or raising them using the lifeline, or could be transported on a diving stage. Most diving work using standard dress was done heavy, with the diver sufficiently negatively buoyant to walk on the bottom. Standard diving dress is also sometimes known in the US as a Diver Dan outfit from the television show of the same name.

In 1939, Christian Lambertsen developed an oxygen rebreather he called the Lambertsen Amphibious Respirator Unit (LARU) and patented it in 1940. He later renamed it the Self Contained Underwater Breathing Apparatus, which, contracted to SCUBA, eventually became the generic term for both open circuit and rebreather autonomous underwater breathing equipment. Lambertson demonstrated the apparatus to the Office of Strategic Services (OSS) who hired him to lead the program to build up the dive element of their maritime unit. After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers.

Northstar is also able to punch at great speeds, which grants him the ability to hurt even the Hulk. In an early issue of Alpha Flight Northstar reveals to readers that his sister Aurora has greater endurance and can fly longer, whereas he can fly faster in the same amount of time.Alpha Flight #1 (1983) Northstar can create cyclones by running in circles, can run up walls and across water, and can breathe while traveling at supersonic speeds. However, if Northstar wanted to travel with someone else at superhuman speeds, they would need a breathing apparatus to keep from asphyxiating.

A slurry pit, also known as a farm slurry pit, slurry tank, slurry lagoon or slurry store, is a hole, dam, or circular concrete structure where farmers gather all their animal waste together with other unusable organic matter, such as hay and water run off from washing down dairies, stables, and barns, in order to convert it, over a lengthy period of time, into fertilizer that can eventually be reused on their lands to fertilize crops. The decomposition of this waste material produces deadly gases, making slurry pits potentially lethal without precautions such as the use of a breathing apparatus with air supply.

The Man in the Moon watches the capsule as it approaches, and it hits him in the eye. Landing safely on the Moon, the astronomers get out of the capsule (without the need of space suits or breathing apparatus) and watch the Earth rise in the distance. Exhausted by their journey, they unroll their blankets and sleep. As they sleep, a comet passes, the Big Dipper appears with human faces peering out of each star, old Saturn leans out of a window in his ringed planet, and Phoebe, goddess of the Moon, appears seated in a crescent-moon swing.

The shark bit into one of the buoys at the top of the cage, which caused the cage to begin sinking. Currie realized that he could either get eaten or drown because he had only a mask, not any breathing apparatus. Currie quickly swam out of the top of the cage and was pulled to safety by the boat's captain, who fended off the shark with blows to its head. In 2007, a commercial shark cage was destroyed off the coast of Guadalupe Island after a great white shark became entangled and tore the cage apart in a frantic effort to free itself.

Sheridan and Theo discuss what happened when Theo introduces a new member of the Order, the same person that led the attack against Edward, but now having had his own "death of personality". Sheridan is initially hostile towards him, but when Theo reminds him about forgiveness and that he will be returning to their monastery on Earth to train him, Sheridan shakes his hand and wishes him good luck. Elsewhere, Lyta reports to Kosh in his quarters without the need for special breathing apparatus. Kosh draws in an ethereal substance from her body to his own.

The Newham Fire Brigade is crewed exclusively by volunteers raised from a community of approximately 300 households. The brigade has approximately 40 active qualified firefighters, some of whom are self-contained breathing apparatus operators. The brigade was supported by a Ladies' Auxiliary, which was later subsumed into the brigade to reflect modern societal standards. The support provided by the Ladies' Auxiliary is now provided by members within the brigade. The brigade appliances are a Hino Ranger 2000-litre 2.4D tanker, a Hino 500 Series 2000-litre 2.4C tanker and a Toyota Landcruiser 400-litre slip-on.

In the spring of 1940 Lord Adrian, Millikan's former advisor at Cambridge, asked Millikan to help the Royal Air Force with the development of a reliable breathing apparatus. According to Adrian, pilots regularly lost consciousness during high-altitude dogfights, and needed "an oxygen delivery system with a demand valve responsive to altitude and activity". Millikan built the device for monitoring the state of pilot's organism in flight (the Millikan oximeter) in 1940 and presented it to the American Physiological Society in 1941. The oximeter was integrated into the pilot's altitude mask and had to be clasped to the earlobe.

Polish Au-2 escape respirator Common design of escape respirator Escape respirator is a portable Breathing apparatus or mask that regenerates breathable air to help provide respiratory protection for emergency escape from areas containing harmful gases and/or IDLH atmospheres. There are two types of escape respirators: air-purifying escape respirators and self- contained escape respirators. Often times, these respirators utilize a easy to don hood and some sort of supplied air tank or filter attachment that cleans the incoming air for the user. Escape respirators are not to be used for anything other than escaping a contaminated environment.

On 29 September 1942 U-255 sailed from Bergen, arriving back at Kiel on 3 October. There the submarine was fitted with a Schnorchel underwater-breathing apparatus before sailing again on 7 January 1943, and arriving at Hammerfest in northern Norway on the 18th. Returning to her old hunting grounds north of Norway, U-255 sailed from Hammerfest on 23 January 1943, and on the 26th, U-255 likely sank the 2,418-ton Soviet merchant ship Krasnyj Partizan with two torpedoes west of Bear Island. The Russian ship had just evaded the pursuing when it went missing.

Many riders missed altogether; others broke the goose's neck without snapping off the head. The American poet and novelist William Gilmore Simms wrote that Goose-pulling largely died out in the United States after the Civil War, though it was still occasionally practised in parts of the South as late as the 1870s; a local newspaper in Osceola, Arkansas reported of an 1870s picnic that "after eats, gander-pulling was engaged in. Mr. W.P. Hale succeeded in pulling in twain the gander's breathing apparatus, after which dancing was resumed." A variant called "rooster pulling" has survived in New Mexico for some time.

Willard Searle in 1969 wearing Standard Diving Dress Searle's first diving experience came in 1946 while serving in the destroyer USS Meredith before transferring to the USS Weiss where he was introduced to Underwater Demolition Team techniques. Searle then trained at the Naval School of Diving and Salvage at the Washington Navy Yard, where he became a deep-sea helium- oxygen diving officer. He was then assigned to two tours at the Charleston Naval Shipyard. From 1957 to 1959, he was actively evaluating equipment ranging from diving watches to closed circuit breathing apparatus design at the Navy Experimental Diving Unit.

Crews using breathing apparatus ("BA"), searching the building for the seat of the fire, found conditions very difficult with thick smoke and the crowded layout of the premises hampering progress. With the arrival of the additional pump from West Marine Fire Station at 11:33, Station Officer Carroll ordered the roof be opened to assist in ventilating the building. This was effected under difficult circumstances, from ladders pitched against the building, and thick smoke began emitting through the hole created. The complex layout of the stock and partitioning of the building created difficulty finding the fire.

Firefighters testing elastomeric respirators, for light use in non-oxygen-deficient environments Elastomeric masks are part of the equipment worn in mining Making logs from rice chaff First responders may use elastomeric respirators, including during smoke simulation exercises. Air- purifying respirators are not effective during firefighting, in oxygen- deficient atmosphere, or in an unknown atmosphere; in these situations an air- supplying respirator such as a self-contained breathing apparatus is recommended instead. Gas masks are extensively used in mining and construction. They are used against paint vapors, solvents, silica dust, and other hazardous particles and gasses.

Oxygen can be absorbed through the lining of the mouth and pharynx, which is rich in blood vessels and acts as a "lung". Although adult swamp eels have virtually no fins, the larvae have large pectoral fins which they use to fan water over their bodies, thus ensuring gas exchange before their adult breathing apparatus develops. When about a fortnight old they shed these fins and assume the adult form. Most species of swamp eel are hermaphrodite, starting life as females and later changing to males, though some individuals start life as males and do not change sex.

The unit consisted of a cylinder of compressed air carried on the back of the diver, connected to a pressure regulator designed by Le Prieur adjusted manually by the diver, with two gauges, one for tank pressure and one for output (supply) pressure. Air was supplied continually to the mouthpiece and ejected through a short exhaust pipe fitted with a valve as in the Fernez design. For the first time a man could breathe underwater with no connection to the surface at all – Le Prieur had invented the open circuit self-contained underwater breathing apparatus – scuba.Commandant Le Prieur.

Le Prieur remarked that the diver could breathe through the mouth or nose, or both, at will, and that it was even possible to speak with another diver by bringing the glass close to their ear, the glass forming a microphone. In 1934 Le Prieur was granted French patent 768083 for an improved hand-controlled self-contained underwater breathing apparatus with full face mask. The patent application was lodged in Paris on 2 February 1934 at 2:32 pm. The patent was awarded on 7 May 1934 and the patent specification was published on 31 July 1934.

Once the strap is looped around a hand or foot, its attached rope is pulled by rescuers, tightening around the arm or leg and pulling the victim out of the confined space. In the event that an entry rescue must be performed, rescue personnel will wear protective clothing appropriate for the situation. This may include a self contained breathing apparatus (SCBA), protective headgear and the use of explosion proof lighting (to prevent igniting any gases). The rescuer may also wear a full body harness with an attached safety line, especially if a vertical descent is required.

In 1957 the publication of Duncan Sandys' Defence White Paper led to the cancellation of many aircraft projects. The company decided to diversify into other markets and took a licence from Drägerwerke, of Germany, to produce compressed air diving and oxygen breathing apparatus. Normalair achieved most success with portable oxygen systems, including the equipment supplied for the first successful ascent, by Tenzing and Hillary, of Mount Everest. Relatively short-lived was Normalair's entry into the automotive air conditioning market, where the systems were optional extras on Wolseley Wolseley 6/110, Austin Westminster 110, Vanden Plas Princess, Land Rovers and some Rolls-Royces.

The missile swap had been seen by many as an even trade that saved face for both sides when considering the capabilities of each to deliver a serious strike to the other. Kennedy had subsequently sought dialogue with Castro to reverse the two nations' acrimonious relationship. As a result of the CIA's continued defiance, tensions between the President and the Agency, festering since the failed Bay of Pigs invasion, continued to escalate. In early 1963, The CIA devised a plot to provide Castro with a diving suit contaminated with fungus and “contaminating the breathing apparatus with tubercle bacilli”.

Gas pressure regulators are used for several applications in the supply and handling of breathing gases for diving. Pressure reducing regulators are used to reduce gas pressure for supply to the diver in demand and free-flow open circuit breathing apparatus, in rebreather equipment, and in gas blending procedures. Back-pressure regulators are used in the exhaust systems of the built-in breathing systems of diving chambers, and in the recovery of used helium based breathing gas for recycling. Some of these regulators must work underwater, others in the more forgiving conditions of the surface support area.

The pressure vessel is a seamless cylinder normally made of cold-extruded aluminium or forged steel. Filament wound composite cylinders are used in fire fighting breathing apparatus and oxygen first aid equipment because of their low weight, but are rarely used for diving, due to their high positive buoyancy. They are occasionally used when portability for accessing the dive site is critical, such as in cave diving. Composite cylinders certified to ISO-11119-2 or ISO-11119-3 may only be used for underwater applications if they are manufactured in accordance with the requirements for underwater use and are marked "UW".

An economic downturn and rising unemployment adds to tension, as German workers seek employment in France but are turned away, since there are hardly enough jobs for French workers. In the French part of the mine fires break out, which they try to contain by building brick walls, with the bricklayers wearing breathing apparatus. The Germans continue to work in their section, but start to feel the heat from the French fires. Three German miners visit a French dance hall and one almost provokes a fight when Francoise, a young French woman, refuses to dance with him.

Monofin Finswimming snorkel Finswimming which is often compared to sports swimming differs from that sport in the use of masks, fins, snorkels and underwater breathing apparatus. This reflects the sport's origins in the underwater diving techniques of snorkelling, breath-hold diving and open circuit scuba diving. Apart from requiring the use of a mask for protection of the eyes and for the ability to see underwater, the international rules have no requirements regarding selection. Centre-mounted snorkels (also known as front snorkels) are the only type approved for use subject to meeting minimum and maximum requirements in tube length and internal diameter.

Crews from Greater Manchester Fire Brigade and West Yorkshire Fire Brigade quickly attended the scene. Co-ordination between the brigades appears to have worked well, perhaps because they had both participated in an emergency exercise in the tunnel a month before. The train crew were persuaded to return to the train, where they uncoupled the three tankers still on the rails and used the locomotive to drive them out. Greater Manchester fire brigade then loaded firefighting equipment onto track trolleys and sent a crew with breathing apparatus (BA) in to begin their firefighting operation at the south end of the train.

Although he entered military service to play in the Navy band, Linhart claimed that during his naval service he was unexpectedly called upon to help fight a fire with inadequate breathing apparatus, causing him chronic lung damage. As a result, Buzz Linhart was decades ahead of his time in objecting to tobacco smoke in the clubs where he wanted to play. A frequent guest of radio host Vin Scelsa, he complained of feeling ill "singin' in the smoke." (source: The Closet, hosted by Vin Scelsa, WFMU 91.1FM, 1967 - 1969) In 1971 Linhart was signed to Eluthra Records.

Swim organizations, for the purposes of their record keeping, often impose other rules. FINA and International Marathon Swimming Hall of Fame do not keep records for swims that employ thermal insulating material, drag reduction fabrics, buoyancy aids, breathing apparatus, propulsion prosthetics, etc. For major channel crossings, most organizations do allow the swimmer to use outside help, an example being that the swimmer swims alongside a boat that uses sophisticated electronics and telecommunications to help the swimmer take the easiest path through surface currents and tides. Such boats can also make the challenge easier for the swimmer by blocking wind and surface chop.

Afterwards, Frank agrees to help Tom beat up Noel but Frank is distracted and Noel flees into an area beneath the houses. Tom and Frank chase after Noel where Frank starts to hallucinate again, snapping out of it just as he comes upon Tom beating Noel with his baseball bat. During his second visit to Burke, the voice again pleads to let him die and this time Frank removes Burke's breathing apparatus, causing him to enter cardiac arrest and ending his life. Frank then heads to Mary's apartment to inform her where Mary seems to accept her father's death.

For this reason, the strategy is sometimes called a two-dimensional or 2D attack. An outdoor fire is always fed with air, and the risk to people is limited as they can move away from it, except in the case of wildfires or bushfires where they risk being easily surrounded by the flames. It might, however, be necessary to protect specific objects like houses or gas tanks against infrared radiation, and thus to use a diffused spray between the fire and the object. Breathing apparatus is often required as there is still the risk of inhaling smoke or poisonous gases.

Pyrene Panorama Limited was established in 1959 when Pyrene purchased the business of Panorama Equipment Limited, which itself dated from 1941. This company was formed originally to manufacture an industrial wide-field vision safety goggle which gave rise to the name-"Panorama". Also in 1959 Pyrene acquired Roberts McClean who in 1931 introduced self-contained compressed air breathing apparatus to the UK and these two companies merged under the Pyrene Panorama flag. In 1976 Fireward Limited, manufacturers since 1964 of plastic-bodied portable dry-powder fire extinguishers also merged with Pyrene Panorama, to form the new Company, Chubb Panorama.
|

A further addition to the Panorama Group came in 1976 when the change from Pyrene Panorama to Chubb Panorama, Submarine and Safety Engineering Limited joined the team. Specialists in self-contained under-water breathing apparatus and diving equipment, their "Dominair" range added considerably to the company's comprehensive coverage of safety equipment. Pyrene was taken over by Chubb and Sons in 1967 and continued to operate under the name Pyrene until 1971 when Chubb Fire Security Limited was formed. In that same year a Bristol Britannia aircraft landed on a carpet of Pyrene foam at Manston piloted by Donald Chubb.

In May 1972, the Sunshine Mine of Kellogg was the site of one of the worst U.S. mining accidents, resulting in the deaths of 91 miners; as a result, every miner in the U.S. now carries a "self-rescuer" (a breathing apparatus made with hopcalite and much simpler than a SCBA), which gives the miner a chance to avoid death due to carbon monoxide poisoning. Eight days after the fire started, two men emerged from the mine. They were found on the 4800 ft (1463 m) level of the mine near a fresh air source. All others trapped in the mine had died.

Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold, or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long- duration deep dives. Atmospheric diving suits (ADS) may be used to isolate the diver from high ambient pressure.

The British adapted the Davis Submerged Escape Apparatus and the Germans adapted the Dräger submarine escape rebreathers, for their frogmen during the war. The Italians developed similar rebreathers for the combat swimmers of the Decima Flottiglia MAS, especially the Pirelli ARO. In the U.S. Major Christian J. Lambertsen invented an underwater free-swimming oxygen rebreather in 1939, which was accepted by the Office of Strategic Services. In 1952 he patented a modification of his apparatus, this time named SCUBA,(an acronym for "self-contained underwater breathing apparatus"), which later became the generic English word for autonomous breathing equipment for diving, and later for the activity using the equipment.

The Voit Rubber Corporation provided most of the diving equipment used in this series, but actual Aqua-Lungs appeared in early episodes. The word "aqualung" was commonly used in speech and in publications as a term for an open-circuit, demand valve-controlled breathing apparatus (even after Air Liquide's patent expired and other manufacturers started making identical equipment), occasionally also for rebreathers, and in figurative uses (such as "the water spider's aqualung of air bubbles"). The word entered the Russian language as the generic noun акваланг ("akvalang"). That word was taken into Lithuanian as the generic noun "akvalangas"; "langas" happens to be Lithuanian for "window", giving a literal meaning "aqua-window".

Essentially, rescue chambers are sealed environments built to sustain life in an emergency or hazardous event such as a truck fire or toxic gas release. They provide a secure area with shelter, water, and breathable air, for people to remain until they are rescued or the hazard subsides. Refuge chambers need to be sealed to prevent the ingress of toxins such as smoke contaminating the breathable air within the chamber. The sealed area has a closed circuit breathing apparatus; where carbon dioxide and other toxins are removed, oxygen is added, and temperature and humidity are maintained, all while protecting occupants from the external threat.

Bernhard Dräger of Lubeck developed an injection system which used a high velocity injection of fresh gas into a divergent nozzle to entrain breathing gas in the loop of a rebreather to circulate the gas at without effort by the diver. By 1899 this had been developed to a stage where it could be used as a portable rebreather. By 1912 it had been developed into a system carried by a diver and used as a semi-closed diving rebreather with a copper helmet which did not need a mouthpiece. This was technically a self-contained underwater breathing apparatus based on the standard diving dress.

During November 1880, a diver was sent down a shaft and 300 m along the tunnel heading to close a watertight door. It was achieved by the lead diver, Alexander Lambert equipped with Henry Fleuss' newly developed self-contained breathing apparatus (SCBA). Work in the area was halted until January 1881 when the Great Spring was temporarily sealed. Ex-GWR 5101 Class engine No.4121 piloting No.4998 Eyton Hall on a mixed freight train through , having climbed the bank up from the Severn Tunnel, 1961 On 26 September 1881, the headings met and efforts transferred to finishing the tunnel and long deep cuttings at either end.

Coffey is able to launch the warhead into the trench, but his sub drifts over the edge, crushing him when it implodes. Bud's mini-sub is inoperable and taking on water; with only one functional diving suit, Lindsey opts to enter deep hypothermia when the ocean's cold water engulfs her. Bud swims back to the platform with her body; there, he and the crew administer CPR and revive her. One SEAL, Ensign Monk, helps Bud use an experimental diving suit equipped with a liquid breathing apparatus to survive to that depth, though he will only be able to communicate through a keypad on the suit.

A healthy person at rest at surface atmospheric pressure expends only a small amount of available effort on breathing. This can change considerably as the density of breathing gas increases at higher ambient pressure. When the energy expended to remove carbon dioxide produces more carbon dioxide than it removes the person will suffer from hypercapnia in a positive feedback cycle ending in unconsciousness and eventually death. Work of breathing is affected by breathing rate, breathing pattern, gas density, physiological factors, and the fluid dynamic details of the breathing apparatus, the namely frictional resistance to flow, and pressure differences required to open valves and hold them open to flow.
|
|
Work of breathing (WOB) is the energy expended to inhale and exhale a breathing gas. It is usually expressed as work per unit volume, for example, joules/litre, or as a work rate (power), such as joules/min or equivalent units, as it is not particularly useful without a reference to volume or time. It can be calculated in terms of the pulmonary pressure multiplied by the change in pulmonary volume, or in terms of the oxygen consumption attributable to breathing. The total work of breathing when using a breathing apparatus is the sum of the physiological work of breathing and the mechanical work of breathing of the apparatus.

The main gas supply for surface-supplied diving can be from high pressure bulk storage cylinders. When the storage cylinders are relatively portable this is known as a scuba replacement system in the commercial diving industry. The application is versatile and can ensure high quality breathing gas in places where atmospheric air is too contaminated to use through a normal low pressure compressor filter system, and is easily adaptable to a mixed gas supply and oxygen decompression provided that the breathing apparatus and gas supply system are compatible with the mixtures to be used. Scuba replacement is often used from smaller diving support vessels, for emergency work, and for hazmat diving.

Currently, language in German as in English, tauchen = "diving" only means in water. Until the middle of the 20th century the German word tauchen = "to dive" also meant "to stay in unbreathable atmosphere". Thus around 1900 a water-cooled fire protection hood with air supply for firefighters was called in German a Feuertaucher (= "fire diver"), and still into the 1940s in German a man with a breathing apparatus for use in unbreathable atmosphere was called a Gastaucher (= "gas diver"). But as escape sets were used more for rescue from sunken submarines and as light diving equipment, the German word "tauchen" was restricted to underwater meanings.

Eustace started his fall by using an explosive device to separate from the helium balloon. The previous altitude record for a manned balloon flight was set at 39.045 kilometers on October 14, 2012 by Felix Baumgartner breaking a record of 34.7 kilometers on May 4, 1961 by Malcolm Ross and Victor Prather in a balloon launched from the deck of the in the Gulf of Mexico.Nicholas Piantanida, while attempting to set a new skydiving jump record, is claimed to have reached 123,800 feet (37.73 km) on February 2, 1966. Piantanida was unable to disconnect his breathing apparatus from the gondola, so the ground crew jettisoned the balloon at the flight ceiling.

For scuba equipment, the industry standard is that breathing apparatus which will be exposed to concentrations in excess of 40% oxygen by volume should be oxygen cleaned before being put into such service. Surface supplied equipment may be subject to more stringent requirements, as the diver may not be able to remove the equipment in an accident. Oxygen cleaning may be required for concentrations as low as 23% Other common specifications for oxygen cleaning include ASTM G93 and CGA G-4.1. Cleaning agents used range from heavy-duty industrial solvents and detergents such as liquid freon, trichlorethylene and anhydrous trisodium phosphate, followed by rinsing in deionised water.

While assisting minesweeping operations prior to landings on Manila Bay's Corregidor Island, Fletcher was hit by an enemy shell which penetrated the No. 1 gun magazine, igniting several powder cases. Bigelow picked up a pair of fire extinguishers and rushed below in a resolute attempt to quell the raging flames. Refusing to waste the precious time required to don rescue-breathing apparatus, Bigelow plunged through the blinding smoke billowing out of the magazine hatch and dropped into the blazing compartment. Despite the acrid, burning powder smoke which seared his lungs, he succeeded in quickly extinguishing the fires and in cooling the cases and bulkheads, thereby preventing further damage to the ship.

In World War I, on November 1, 1918, Raffaele Paolucci and Raffaele Rossetti of the Regia Marina rode a manned torpedo (nicknamed Mignatta or "leech") into the harbour of Pula, where they sank the battleship Jugoslavija, of the navy of the State of Slovenes, Croats and Serbs, formerly the Austro-Hungarian battleship , and the freighter Wien using limpet mines. They had no underwater breathing sets, and thus had to keep their heads above water to breathe. They were discovered and taken prisoner as they attempted to leave the harbour. In the 1920s, sport spearfishing without breathing apparatus became popular on the Mediterranean coast of France and Italy.

Recreational scuba diver Diver looking at a shipwreck in the Caribbean Sea. Scuba diving is a mode of underwater diving where the diver uses a self- contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a mixture of air and oxygen called enriched air or nitrox has become popular due to its benefit of reduced nitrogen intake during long or repetitive dives.

Divers will usually enter the water with positive buoyancy, as this allows them to make final surface checks, signal to the boat that they are OK and co-ordinate descent with a buddy, but there are occasions when negative buoyancy entries are chosen to avoid excessive drift in a strong current, in which case all pre-dive checks must be done on the boat, the buoyancy compensator, and where applicable, the dry-suit emptied of gas, and the breathing apparatus function thoroughly checked before entering the water. The risk of injury if there is an equipment problem is greater for negative entry, particularly with breathing gas failures.

Although Fluorinert was intended to be inert, the Lawrence Livermore National Laboratory discovered that the liquid cooling system of their Cray-2 supercomputers decomposed during extended service, producing some highly toxic perfluoroisobutene.Kwan, J. Kelly, R, Miller G. Presentation at the American Industrial Hygiene Conference, Salt Lake City, UT, May 1991 Catalytic scrubbers were installed to remove this contaminant. The science-fiction film The Abyss (1989) depicted an experimental liquid-breathing system, in which the use of highly oxygenated Fluorinert enabled a diver to descend to great depths. While several rats were shown actually breathing Fluorinert, scenes depicting actor Ed Harris using the fluid-breathing apparatus were simulated.

Fire stations are equipped with specialised equipment, such as firefighting and rescue vehicles, Ambulances, breathing apparatus, hydraulic rescue tools, electric chain saws, concrete or steel cutters, chemical protective suits, fire proximity suits, rescue rocket devices, self/rope rescue devices and search cameras. The Mumbai Fire Brigade's first response vehicles are fire fighting trucks known as Motor Pumps, equipped with ladders, water tanks, and hydraulic rescue tools. Currently, the Mumbai Fire Brigade uses MPs manufactured by Tata and MAN. For larger fires, the Mumbai Fire Brigade uses brigades known as 'Jumbo Tankers' which have the capacity to hold between 14,000 and 18,000 litres of water.

In English-speaking countries the CG45 was commercialized under the name of Aqua- Lung, a word coined by Cousteau himself on that purpose. In the USA during World War II the American military physician Christian J. Lambertsen designed a wartime frogman's rebreather which in 1952 got called the SCUBA (acronym for Self-Contained Underwater Breathing Apparatus),See Lambertsen's homage by the Passedaway.com website and later the name (changing to 'scuba' and treated as a word) was used to mean any underwater breathing set. In Britain the word "aqualung" became a generic trademark for open-circuit underwater breathing sets and stayed so for many years.

Since the tool is attached several feet behind the firefighter, its use will not hinder a firefighter wearing a Self-contained breathing apparatus. For larger attack lines, such as a hand line, second or third firefighters can use additional hose straps to secure the hose farther behind the nozzle operator, to provide additional leverage against the water pressure. Since multiple hose straps will typically be available to a team of firefighters, they can be used in combination to handle a variety of other tasks. For example, if a task requires greater length than that of a single hose strap, two hose straps may be connected via girth hitch.

As noted, such suits are usually limited to just 15–20 minutes of use by their mobile air supply. With each suit described here, there is a manufactured device designed to protect the respiratory system of the wearer (called a respirator) while the suit/ensemble is used to protect skin exposed to potential hazardous dermal agents. A respirator may be something as simple as a headband strap filtering facepiece respirator (FFR), to a head harness negative pressure full face respirator (air-purifying respirator/APR), to a full face, tight fitting, closed breathing air, or open circuit, self-contained breathing apparatus (CC- SCBA or SCBA).

Soon after the "Man trapped" message was sent, Deputy Firemaster McGill turned out to Kilbirnie Street, hearing a "Make Pumps 8" message whilst en route, arriving around 12:18 to take command. With the discovery that Fireman Rook was missing, a rescue party was sent in to get him, but had to be pulled out due to exhaustion. Divisional Officer Quinn was not prepared to leave Rook to his fate, and a second rescue attempt was mounted. Between around 12:05 and 12:20, Leading Fireman Crofts, Firemen Bermingham, Finlay, Hooper and McMillan donned breathing apparatus and, with Quinn, returned to the attic floor.

Lung over-pressure injury in ambient pressure divers using underwater breathing apparatus is usually caused by breath-holding on ascent. The compressed gas in the lungs expands as the ambient pressure decreases causing the lungs to over-expand and rupture unless the diver allows the gas to escape by maintaining an open airway, as in normal breathing. The lungs do not sense pain when over-expanded giving the diver little warning to prevent the injury. This does not affect breath-hold divers as they bring a lungful of air with them from the surface, which merely re-expands safely to near its original volume on ascent.

Sapien appeared in the film's 2008 sequel, Hellboy II: The Golden Army, in which he was played by Doug Jones who provides his speaking parts. He doesn't wear his breathing apparatus as much in this film, and he shows his marksman skills in the film. He is also the one who discovers Liz's pregnancy in the mission where Hellboy is revealed to the world. He falls in love with the elf Princess Nuala, which leads to his helping Prince Nuada by giving him the magical crown piece (to control the Golden Army) for her safety, but Princess Nuala kills herself to prevent Nuada from killing Hellboy.

The Type 224 was a big disappointment to Mitchell and his design team, who immediately embarked on a series of "cleaned-up" designs, using their experience with the Schneider Trophy seaplanes as a starting point. This led to the Type 300, with retractable undercarriage and a wingspan reduced by . This design was submitted to the Air Ministry in July 1934, but was not accepted.Price 1982, p. 16. It then went through a series of changes, including the incorporation of an enclosed cockpit, oxygen-breathing apparatus, smaller and thinner wings, and the newly developed, more powerful Rolls-Royce PV-XII V-12 engine, later named the "Merlin".

Breathing gas at depth from underwater breathing apparatus results in the lungs containing gas at a higher pressure than atmospheric pressure. So a free-diver can dive to 10 metres (33 feet) and safely ascend without exhaling, because the gas in the lungs had been inhaled at atmospheric pressure, whereas a diver who deeply inhales at 10 metres and ascends without exhaling has lungs containing twice the amount of gas at atmospheric pressure and is very likely to suffer life-threatening lung damage. Explosive decompression of a hyperbaric environment can produce severe barotrauma, followed by severe decompression bubble formation and other related injury. The Byford Dolphin incident is an example.

Its similarity to the final design of Vader's costume demonstrates that McQuarrie's earliest conception of Vader was so successful that very little needed to be changed for production. Working from McQuarrie's designs, the costume designer John Mollo devised a costume that could be worn by an actor on-screen using a combination of clerical robes, a motorcycle suit, a German military helmet and a military gas mask. The prop sculptor Brian Muir created the helmet and armour used in the film. The sound of the respirator function of Vader's mask was created by Ben Burtt using modified recordings of scuba breathing apparatus used by divers.

The breathing apparatus widely used at the incident was the Siebe Gorman Proto industrial oxygen rebreather. This was a one-hour closed circuit constant flow unit consisting of a breathing bag (containing a CO2 absorbent material) which hung in front of the wearer, oxygen cylinder (sat horizontally across the small of the back), mouthpiece, nose clip, and separate eyes-only goggles. It was successfully used for many years by the UK fire service, but could be hot in use and was complex to use and service. On near exhaustion of the oxygen supply, a whistle sounded to tell the wearer that he had only a few minutes supply left.

When the diver exhales, one-way valves made from a flexible air-tight material flex outwards under the pressure of the exhalation, letting gas escape from the chamber. They close, making a seal, when the exhalation stops and the pressure inside the chamber reduces to ambient pressure. The vast majority of demand valves are used on open circuit breathing apparatus, which means that the exhaled gas is discharged into the surrounding environment and lost. Reclaim valves can be fitted to helmets to allow the used gas to be returned to the surface for reuse after removing the carbon dioxide and making up the oxygen.

Tektite I underwater habitat with ambient pressure divers using scuba In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold, or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives. Immersion in water and exposure to cold water and high pressure have physiological effects on the diver which limit the depths and duration possible in ambient pressure diving. Breath-hold endurance is a severe limitation, and breathing at high ambient pressure adds further complications, both directly and indirectly.

During this period, she also participated in occasional anti-submarine duty along the East coast. On 19 March 1945 she steamed to the aid of the coastal minesweeper , saving her from sinking.clad only in heavy underclothing and using a face mask breathing apparatus, Thomas John Kushnerick, Boilermaker, 1st class,U.S.N. Of Freeland, Pa. descended 4times in ice-cold water in the darkness to secure a patch over the hole in the minesweepers hull due to a parted flange in the sea chest. Between 15 July and 18 September 1945, Bray was at Charleston Navy Yard where she underwent conversion to a high speed transport.

The compound is stable and hazardous decomposition products should not be produced during normal use, but in a fire can produce carbon dioxide, carbon monoxide and nitrogen oxides, so firefighters are advised to wear self-contained breathing apparatus. State regulatory disclosures indicate it contains ethyl acrylate. According to the US EPA, "the hydrochloric salt of this product is only acceptable for use in the production of asphalt emulsions, and the emulsions may only be used in asphalt paving applications." Standard usage involves partial neutralization of basic indulin with hydrochloric acid to form a salt, for a 1.0:1.1 ratio of indulin to its salt.

Leavitt's suit was of his own design and construction. The most innovative aspect of Leavitt's suit was the fact that it was completely self-contained and needed no umbilical, the breathing mixture being supplied from a tank mounted on the back of the suit. The breathing apparatus incorporated a scrubber and an oxygen regulator and could last for up to a full hour. In 1924 the Reichsmarine tested the second generation of the Neufeldt and Kuhnke suit to , but limb movement was very difficult and the joints were judged not to be fail-safe, in that if they were to fail, there was a possibility that the suit's integrity would be violated.

Fire Police are volunteer fire brigade/company members who based upon their jurisdictional authority, receive sworn police powers, special training, and support firefighting efforts at emergency incidents. In addition to securing firefighting equipment, incident and fire scenes, and the station itself, fire police perform traffic and crowd control. In some jurisdictions, fire police are exterior firefighters and may be called upon at fire scenes to perform any of the duties of an interior firefighter except those that require a self- contained breathing apparatus. On occasion, fire police also assist regular police: they perform road closures, traffic control, crowd control at public events, missing persons searches, parade details, salvage, security, and other miscellaneous tasks as requested.

A vehicle that comes in all sizes, depending of the equipment stowed. Equipment might be specialized gear for water rescue operations or hazmat. Another variation is the Wechselladerfahrzeug (WLF) which is a specialized, heavy-duty truck WLFs and their modules used by the Cologne Fire Department with a mounted hydraulic crane arm behind the truck's cabin designed to lift heavy containers or modules (called Abrollbehälter) which contain specialized equipment (examples include mobile command modules/trailers, rescue gear modules, Self-Contained Breathing Apparatus modules, HazMat or environmental modules) # Aerial ladders, like the Drehleiter (DL or DLK). A large truck with a telescopic ladder (DL), often with an attached bucket or platform at the end (DLK).

Fire rescue unit A fire rescue unit (FRU) is a specialist heavy-rescue vehicle. The FRUs are equipped with heavy lifting, winching, cutting and pulling tools, floodlighting, longer-duration breathing apparatus (vital for rescuing people from tunnels deep underground, for example), portable generators and other specialised equipment. FRU crews are specially trained and equipped to handle complex rescues, including those from road and rail accidents, water, mud and ice, urban search and rescue incidents such as collapsed buildings, chemical spills and difficult rescues at height. Nine of the Brigade's fleet of FRUs were mobilised to the 7/7 bombings in 2005 and after the attacks the LFB increased its number of FRUs from 10 (including one reserve) to 16.

A number of Chariot operations were attempted, most notably Operation Title in October 1942, an attack on the German battleship Tirpitz, which had to be abandoned when a storm hit the fishing boat which was towing the Chariots into position. The last and most successful British operation resulted in sinking two liners in Phuket harbour in Thailand in October 1944. An oxygen rebreather set called the Lambertsen Amphibious Respirator Unit (LARU) was invented in the United States 1939 by Christian Lambertsen, and was patented in 1940. Lambertsen later renamed it the Self Contained Underwater Breathing Apparatus, which, contracted to SCUBA, eventually became the generic term for both open circuit and rebreather autonomous underwater breathing equipment.

The Red Hood first appeared in Detective Comics #168 (February 1951), in the story "The Man Behind The Red Hood!". In the original continuity, the man later known as Batman's arch nemesis "the Joker" was a master criminal going by the Red Hood alias, claiming to be a lab worker intending to steal $1,000,000 and retire. His costume consisted of a tuxedo, a red cape, and a large domed red helmet with no eye holes or facial features. While attempting to rob a playing card company, he was cornered and dove into a catch basin full of chemicals and swam to freedom, surviving because of a special breathing apparatus built into the helmet.

Unable to escape due to the fire outside his room, the pilot kept this up for some time. Finally, an enlisted sailor discovered his plight and was able to supply him with a firehose, a battle lantern, and an Oxygen Breathing Apparatus; for the duration of the fire, the pilot used the hose to fight the fire and cool his stateroom, and keep the fire from spreading again into the room. Nearby, the executive officer of the air wing's Crusader squadron, finding himself in a similar situation, stripped naked and forced his way through his porthole. He was able to obtain a firefighting suit, and later helped the ship's fire marshal in organizing firefighting parties.

The standard fire engine transports firefighters to the scene, provides a limited supply of water with which to fight the fire, and carries equipment needed by the firefighters for most firefighting scenarios. The tools carried on the fire engine will vary greatly based on many factors including the size of the department and the usual situations the firefighters handle. For example, departments located near large bodies of water or rivers are likely to have some sort of water rescue equipment. Standard tools found on nearly all fire engines include ladders, hydraulic rescue tools (often referred to as the jaws of life), floodlights, fire hose, fire extinguishers, self-contained breathing apparatus, and thermal imaging cameras.

The current balloon flight record was set by Malcolm Ross (USNR) and Victor Prather (USN), who took the Strato-Lab V balloon to 34,668 m (113,740 ft) on 4 May 1961 above the Gulf of Mexico. The balloonists landed successfully, but Victor Prather slipped from the helicopter lift harness while being transferred to a waiting aircraft carrier, and he drowned before US Navy divers could rescue him. Nicholas Piantanida, while attempting to set a new skydiving jump record, is claimed to have reached 123,800 feet (37.73 km) on 2 February 1966. Piantanida was unable to disconnect his breathing apparatus from the gondola, so the ground crew jettisoned the balloon at the flight ceiling.

It is also preferable that the gas is delivered smoothly without any sudden changes in resistance while inhaling or exhaling, and that the regulator does not lock up and either fail to supply gas or free- flow. Although these factors may be judged subjectively, it is convenient to have standards by which the many different types and manufactures of regulators may be objectively compared. Various breathing machines have been developed and used for assessment of breathing apparatus performance. Ansti Test Systems developed a turnkey system that measures the inhalation and exhalation effort in using a regulator, and produces graphs indicating the work of breathing at the set depth pressure and respiratory minute volume for the gas mixture used.

However, this was later commuted to a life sentence, and Pierre-Antoine was released in 1954. During the 1940s, Cousteau is credited with improving the Aqua-Lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self-contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur. Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan.

Scuba diving has roots in the many small and enthusiastic snorkelling and spearfishing clubs in the decades just before and after the Second World War. After the invention of the "aqualung" by Cousteau and Gagnan, the first commercially underwater breathing apparatus became available for sale for sporting purposes in the late 1940s. As the new sport of scuba diving rapidly expanded through the 1950s, several sporting organisations—notably the YMCA—began programmes to train swimming enthusiasts in this new aquatic pastime, and began to codify what they believed were proper practises for this expanding sport. The YMCA considered the buddy system a useful corollary to the "never swim alone" rule of their swimming and lifesaving programmes.

These were later auctioned off to raise money for the Pike River mining relief fund. On 17 March 2011, after attending a national memorial service for the earthquake in Christchurch, Prince William visited Greymouth and met families affected by the disaster. On 27 June 2011, The Australian featured an article titled "Miners doomed by fatal flaws" which alleged that Peter Whittall had not ensured the Pike River Mine had installed safety measures common in Australia, but not legally required in New Zealand. The possible safety measures not used in the Pike River Mine were; a "tube bundle" gas monitoring system, stocks of food and water, breathing apparatus, and a second escape route.

After the war, Delve was appointed Chief Officer of the reconstituted London Fire Brigade in 1948. Challenges included provision of fire services to tower blocks and to traffic accidents, and the movement of hazardous materials across the capital (in 1958, Delve produced a report, Fireman's Handbook of Hazardous Industries, published by London County Council). Under his leadership, street-based fire alarms were replaced by the '999' system (first introduced in central London in 1937), fire appliances were modernised and fire stations rebuilt. Major fires in Covent Garden market (1949 and 1954), the Goodge Street deep tunnels (1956), and Smithfield meat market basement (1958 - during which two firemen died) led to changes in procedures relating to breathing apparatus.

Diving equipment other than breathing apparatus is usually reliable, but has been known to fail, and loss of buoyancy control or thermal protection can be a major burden which may lead to more serious problems. There are also hazards of the specific diving environment, and hazards related to access to and egress from the water, which vary from place to place, and may also vary with time. Hazards inherent in the diver include pre-existing physiological and psychological conditions and the personal behaviour and competence of the individual. For those pursuing other activities while diving, there are additional hazards of task loading, of the dive task and of special equipment associated with the task.

The British adapted the Davis Submerged Escape Apparatus and the Germans adapted the Dräger submarine escape rebreathers, for their frogmen during the war. In the U.S. Major Christian J. Lambertsen invented an underwater free- swimming oxygen rebreather in 1939, which was accepted by the Office of Strategic Services. In 1952 he patented a modification of his apparatus, this time named SCUBA (an acronym for "self-contained underwater breathing apparatus"), which became the generic English word for autonomous breathing equipment for diving, and later for the activity using the equipment. After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers.

Recreational diver putting on his scuba set before diving The defining equipment used by a scuba diver is the eponymous scuba, the self-contained underwater breathing apparatus which allows the diver to breathe while diving, and is transported by the diver. As one descends, in addition to the normal atmospheric pressure at the surface, the water exerts increasing hydrostatic pressure of approximately 1 bar (14.7 pounds per square inch) for every 10 m (33 feet) of depth. The pressure of the inhaled breath must balance the surrounding or ambient pressure to allow inflation of the lungs. It becomes virtually impossible to breathe air at normal atmospheric pressure through a tube below three feet under the water.

Australia :Queensland: – Safety in Recreational Water Activities Act 2011 (the SRWA Act) and the Safety in Recreational Water Activities Regulation 2011 (the Regulation). Canada South Africa – Diving regulations to the Occupational Health and Safety Act, authorised by the Minister of Labour. The South African diving regulations regulate professional diving using breathing apparatus, and specifically exclude instruction of recreational divers and recreational dive leadership. They apply only where the Occupational Health and Safety Act applies, so do not cover diving in minerals and energy industries, which have different safety legislation. There have been two versions of the Diving Regulations, dated 2001 and 2009 (sometimes referred to as Diving Regulations 2010 at they were published in January 2010.

Some critics of holistic dentistry practice also note that the fees charged by such practitioners are generally several times higher than those of mainstream dentists. Some claim that alternative dentistry is merely the exploitation of niche health beliefs and gimmicks to justify higher fees. A potential example of this is the Cavitat, a non validated ultrasound device purported to be able to detect alleged lesions described "cavitations" (see: neuralgia-inducing cavitational osteonecrosis), or the non evidence based utilization of breathing apparatus by certain "biologic dentists" during removal of amalgam fillings, intended to reduce mercury toxicity by eliminating inhaled airborne material. However, others argue that such practices are not representative of the entire field of holistic dentistry.

This patrol was uneventful for the first three weeks during the Atlantic crossing as she deliberately avoided the highly-effective allied countermeasures. The last contact with the boat was on 23 October 1944 reporting trouble with its Schnorchel underwater- breathing apparatus after which nothing more was heard from her. It is possible she was sunk in an unrecorded encounter with an Allied ship or aircraft, or more likely she suffered some unknown catastrophic accident which claimed the boat and all its crew.A large number of German U-boats had been lost to snorkel defects, and its possible this was the cause of the loss of U-1226 Whatever the cause, she was given up for lost in mid-November.

US law obliges the employer to accurately measure air pollution at workplaces. The results of such measurements are used to assess whether short-term inhalation of harmful substances may lead to irreversible and significant deterioration of health, or death (IDLH concentrations). If concentrations exceed the IDLH, the standard allows the use of only the most reliable respirators - SAR or self-contained breathing apparatus: with pressure-demand air supply in the full facepiece mask ( §(d)(2)). If the concentration of a harmful substance is less than the IDLH, the coefficient of air pollution for the harmful substance (Hazard Factor) is determined, which is equal to the ratio of this concentration to the PEL (TLV, OEL) for the harmful substance.

Latent hypoxia affects the diver on ascent Latent hypoxia occurs when a diver under pressure has a tissue oxygen concentration that is sufficient to support consciousness at that pressure, but insufficient at surface pressure. This problem is associated with freediving blackout and the presence of hypoxic breathing gas mixtures in underwater breathing apparatus, particularly in diving rebreathers. The term latent hypoxia strictly refers to the situation while the potential victim is still conscious, but is also loosely applied to the consequential blackout, which is a form of hypoxic blackout also referred to as blackout of ascent or deep water blackout, though deep water blackout is also used to refer to the final stage of nitrogen narcosis.

The building was built in 1897 from a design by Bangor architect Wilfred E. Mansur, and represents one of his finest works in the Romanesque style. Built in the days when fire equipment was drawn by horses, it served the city as a fire station until 1993, when it was converted into a museum, which is operated by the members of the Bangor Fire Department. It is home to a 1917 Garford Pumper, the first motorized fire engine used by the nearby Old Town Fire Department as well as Gamewell Fire Boxes, a collection of antique breathing apparatus, and other historic fire fighting equipment and engines. Admission is free, open Saturdays 9-12 through the summer.

Based on these tests, Momsen had several changes in mind for the bell, and after nearly two years of experimentation full of highly interesting results, the final bell was evolved and christened a "rescue chamber." This success was catalyst for gaining approval for development of the submarine rescue chamber in 1930. Before he could make these changes, Momsen went to the Bureau of Construction and Repair to work on an underwater breathing apparatus for individual escapes. Momsen turned to devising the "Momsen Lung", demonstrating it successfully in a series of unauthorized experiments in the Anacostia and Potomac Rivers, and finally attracted enough favorable attention to see the lung adopted by the Navy in 1929.

Use of the sea for leisure developed in the nineteenth century, and became a significant industry in the twentieth century. Maritime leisure activities are varied, and include self-organized trips cruising, yachting, powerboat racing and fishing; commercially organized voyages on cruise ships; and trips on smaller vessels for ecotourism such as whale watching and coastal birdwatching. Scuba diver with face mask, fins and underwater breathing apparatus Humans enjoy venturing into the sea; children paddle and splash in the shallows and many people take pleasure in bathing and relaxing on the beach. This was not always the case, with sea bathing becoming the vogue in Europe in the 18th century after Dr. William Buchan advocated the practice for health reasons.

The Sleeping Beauty was designed to carry up to of explosives as well as being able to be dropped near its target by a heavy bomber. Fore and central trimming tanks within the hull can be flooded to sink the craft underwater or have compressed air blown in them to surface the craft. The pilot controlled the craft by a joystick that is connected to the rudder and hydroplanes, breathed through a Siebe Gorman Salvus MkII Amphibian rebreather or Dunlop Underwater Swimming Breathing Apparatus (UWSBA), and would have to come close to the surface to establish his whereabouts. The canoe can also be paddled or moved by raising the mast and setting a sail.

Trefentanil has very similar effects to alfentanil, much like those of fentanyl itself but more potent and shorter lasting. Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear. The risk of respiratory depression is especially high with potent fentanyl analogues such as alfentanil and trefentanil, and these drugs pose a significant risk of death if used outside of a hospital setting with appropriate artificial breathing apparatus available.

The British-invented M3 Canal Defence Light used to illuminate the bridge and river area at night The Germans floated a barge down the river carrying explosives but the U.S. forces captured it. They floated mines down the river, but they were intercepted by a series of log and net booms that the 164th Engineer Combat Battalion had built upstream to protect the tactical bridges. Hitler summoned special operations commander Otto Skorzeny, who on 17 March sent a special naval demolitions squad using Italian underwater breathing apparatus to plant mines. Before they could set out, they learned that the Ludendorff Bridge had collapsed, and Skorzeny ordered the seven SS frogmen to instead attack the pontoon bridge between Kripp and Linz.

The classes of hazards include the aquatic environment, the use of breathing equipment in an underwater environment, exposure to a pressurised environment and pressure changes, particularly pressure changes during descent and ascent, and breathing gases at high ambient pressure. Diving equipment other than breathing apparatus is usually reliable, but has been known to fail, and loss of buoyancy control or thermal protection can be a major burden which may lead to more serious problems. There are also hazards of the specific diving environment, and hazards related to access to and egress from the water, which vary from place to place, and may also vary with time. Hazards inherent in the diver include pre-existing physiological and psychological conditions and the personal behaviour and competence of the individual.

Diving equipment other than breathing apparatus is usually reliable, but has been known to fail, and loss of buoyancy control or thermal protection can be a major burden which may lead to more serious problems. There are also hazards of the specific diving environment, which include strong water movement and local pressure differentials, and hazards related to access to and egress from the water, which vary from place to place, and may also vary with time. Hazards inherent in the diver include pre- existing physiological and psychological conditions and the personal behaviour and competence of the individual. For those pursuing other activities while diving, there are additional hazards of task loading, of the dive task and of special equipment associated with the task.

Later they were nicknamed "Uomini Rana", Italian for "frog men" This special corps used an early oxygen rebreather scuba set, the Auto Respiratore ad Ossigeno (A.R.O), a development of the Dräger oxygen self-contained breathing apparatus designed for the mining industry and of the Davis Submerged Escape Apparatus made by Siebe, Gorman & Co and by Bergomi, designed for escaping from sunken submarines. The Italian frogmen trained in La Spezia, Liguria, using swimfins, rubber dry suit, and the new A.R.O. scuba unit. After Italy declared war, the Decima Flottiglia MAS (Xª MAS) attempted several attacks on British naval bases in the Mediterranean between June 1940 and July 1941, but none was successful, because of equipment failure or early detection by British forces.

Diving equipment is equipment used by underwater divers to make diving activities possible, easier, safer and/or more comfortable. This may be equipment primarily intended for this purpose, or equipment intended for other purposes which is found to be suitable for diving use. The fundamental item of diving equipment used by divers is underwater breathing apparatus, such as scuba equipment, and surface-supplied diving equipment, but there are other important pieces of equipment that make diving safer, more convenient or more efficient. Diving equipment used by recreational scuba divers is mostly personal equipment carried by the diver, but professional divers, particularly when operating in the surface supplied or saturation mode, use a large amount of support equipment not carried by the diver.

7 The development of scuba gear allowed researchers to visually explore the oceans as it contains a self-contained underwater breathing apparatus allowing a person to breathe while being submerged 100 to 200 feet into the ocean. Submersibles were built like small submarines with the purpose of taking marine scientists to deeper depths of the ocean while protecting them from increasing atmospheric pressures that cause complications deep under water. The first models could hold several individuals and allowed limited visibility but enabled marine biologists to see and photograph the deeper portions of the oceans. Remotely operated underwater vehicles are now used with and without submersibles to see the deepest areas of the ocean that would be too dangerous for humans.

Although there are several accepted techniques > for octopus wrestling, the really sporty way requires that the human diver > go without artificial breathing apparatus. H. Allen Smith wrote an article for True magazine in 1964, collected in Low Man Rides Again (1973), about a man named O'Rourke whom he dubs the "Father of Octopus Wrestling". According to information Smith collected from Idwal Jones and other sources, O'Rourke and a partner developed a business in the late 1940s of fishing for octopuses, with O'Rourke serving as live bait, and his partner hauling him out of the water after an octopus was sufficiently wrapped around him. > All this while O'Rourke was becoming perhaps the world's greatest authority > on the thought processes and the personality of the octopus.

The first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash, the system giving a dive duration of up to about three hours. This apparatus had no way of measuring the gas composition during use. During the 1930s and all through World War II, the British, Italians and Germans developed and extensively used oxygen rebreathers to equip the first frogmen.

Diving Physics are the aspects of physics which directly affect the underwater diver and which explain the effects that divers and their equipment are subject to underwater which differ from the normal human experience out of water. These effects are mostly consequences of immersion in water; buoyancy, the hydrostatic pressure of depth, the effects of the pressure on breathing gases and gas spaces in the diver and equipment, the inertial and viscous effects on diver movement, and the heat transfer effects. Other effects are the physical influences of the underwater environment on human sensory perception. An understanding of the physics is useful when considering the physiological effects of diving, the hazards and risks of diving, the working of underwater breathing apparatus, buoyancy control and buoyant lifting.

Aircraft Handlers use various types of vehicles and equipment to complete their fire fighting tasks, most of which is the same as the equipment used by most civil fire services, with the exception of the vehicles. At Royal Naval Air Stations, Aircraft Handlers are employed mainly at fire stations where they will use two types of fire vehicle, these being the Rapid Intervention Vehicle (RIV) and the Major Foam Vehicle (MFV). They also use other types of equipment such as Drager breathing apparatus, Clan Lucas cutting equipment, various sized extending ladders and airbag lifting equipment. Aircraft Handlers also use different equipment when they are based on board ships, such as NMATT tractors, EN Mechanical Handlers and RAM to move aircraft.

Contamination of the breathing gas will have effects that depend on the concentration, the ambient pressure, and the specific contaminants present. Carbon monoxide produced by overheating of the compressor, or by contamination of the intake air by internal combustion engine exhaust gas is a well known risk, and can be mitigated by using hopcalite catalyst in the high pressure filter. Contamination by carbon dioxide is unusual in open circuit breathing apparatus, as natural air usually has a low enough content not to be a problem at the ambient pressures of most dives. It is a relatively common problem for rebreathers, as the metabolically produced carbon dioxide in the exhaled gas must be removed chemically by the scrubber before the gas can be breathed again.

A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than , the equivalent of . The typical diver's watch will have a water resistance of around , though modern technology allows the creation of diving watches that can go much deeper. A true contemporary diver's watch is in accordance with the ISO 6425 standard, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of or more. Watches conforming to ISO 6425 are marked with the word DIVER'S to distinguish ISO 6425 conformant diving watches from watches that might not be suitable for actual scuba diving.

This consisted of designated firefighter search and rescue teams (termed "emergency crews") stationed at self-contained breathing apparatus (SCBA) control entry points, equipped with emergency SCBA specifically designed to be worn by unconscious, injured or trapped firefighters. The National Fire Protection Association (NFPA) and the United States Occupational Safety and Health Administration (OSHA) have requirements for some type of FAST/RIT at structure fires. These standards require that a minimum of two fire fighters be standing by in full personal protective equipment (PPE) while other crew members are working in a hazardous atmosphere. The standards are the result of a series of incidents where fire fighters became lost, trapped or disoriented while fighting a structure fire without a FAST present.

At shallow depths, a diver using open-circuit breathing apparatus typically only uses about a quarter of the oxygen in the air that is breathed in, which is about 4 to 5% of the inspired volume. The remaining oxygen is exhaled along with nitrogen and carbon dioxide – about 95% of the volume. As the diver goes deeper, much the same mass of oxygen is used, which represents an increasingly smaller fraction of the inhaled gas. Since only a small part of the oxygen, and virtually none of the inert gas is consumed, every exhaled breath from an open-circuit scuba set represents at least 95% wasted potentially useful gas volume, which has to be replaced from the breathing gas supply.

However, the organisation has drawn attention to more serious issues, having spoken out against, among other incidents, the suspension of a fireman for refusing to shave off his goatee and the banning of beards among ExxonMobil oil workers (in both cases employers claimed that beards interfered with breathing apparatus). Flett believes that an issue of "real discrimination" exists against men with beards. Although he admits that a beard, unlike race and gender, is a matter of choice, he has claimed that beardism is associated with more serious forms of discrimination: The size of the organisation is unknown; Flett refers to the organisation as "an informal network" and has claimed "a few hundred supporters" in the past. He is the organisation's sole spokesman in the media.

The Siamese fighting fish, Betta splendens, originally bred for staged fights, has become popular in the aquarium trade The Siamese fighting fish is perhaps the most popular labyrinth fish in the aquarium trade. The paradise fish also has a long aquarium history and was one of the first aquarium fish introduced to the West. Many species of gouramies, particular the three spot gourami and the dwarf gourami, are commercially bred for the trade, and several color morphs are commonly available. Because of their capability to use atmospheric oxygen, these fish generally are not so dependent on a form of aeration in their tanks, as they can rise to the surface of the water and take a breath, or breathing apparatus.

Under the leadership of William G. Brombacher at the National Bureau of Standards, Iberall worked on instrument theory, safety equipment, and measurement problems such as the physics of the atmosphere. At that time, the US Navy and US Air Force were creating aircraft that could travel further and further into the upper atmosphere. Pilots were being affected at the higher altitudes, which led to funding of studies of human physiology in order to understand how the body responds to high G forces and reduced oxygen. He also worked on the development of a new breathing apparatus that led to undersea Scuba innovations. Retrieved November 24, 2016 At the Rand Development Corporation, Retrieved November 24, 2016 Iberall worked on engineering and physics problems.

The underwater environment presents a constant hazard of asphyxiation due to drowning. Breathing apparatus used for diving is life-support equipment, and failure can have fatal consequences – reliability of the equipment and the ability of the diver to deal with a single point of failure are essential for diver safety. Failure of other items of diving equipment is generally not as immediately threatening, as provided the diver is conscious and breathing, there may be time to deal with the situation, however an uncontrollable gain or loss of buoyancy can put the diver at severe risk of decompression sickness, or of sinking to a depth where nitrogen narcosis or oxygen toxicity may render the diver incapable of managing the situation, which may lead to drowning while breathing gas remains available.

Rodewald's Fire Station Although more a form of public service than a club, Rodewald has a volunteer fire brigade consisting of three active groups (one per Bauernshaft), a senior members association and a youth organisation. All active members must have attended a form of basic training and continue to develop their skills during scheduled monthly meetings where continuance training is delivered or equipment and hydrants are tested and maintained. Regional courses are also available in group leadership, the use of breathing apparatus, vehicle maintenance and radio operation. During an emergency the alarm is raised by the use of numerous civil defence sirens signalling that all active members within the vicinity are to make their way to the centrally located fire station and man the two fire engines and minibus where needed.

Whole-time firefighters attend training school for an initial period of 13–20 weeks, depending on the fire and rescue service they have joined. On-call firefighters now undertake the same training modules as full-time recruits, spread over a greater period of time due to full-time employment job commitments. The new National Firefighter Training Syllabus is now widely- adopted and consists of a three-week "core skills" module, a two-week breathing apparatus module, a one-week HAZMAT module, a one-week road traffic collision module, plus several weekend trauma care/EMT and first aid courses. On completion of this, firefighters then enter an on station development stage over a three-year period, once they have completed their development stage they then become competent and receive a higher level of pay.

Oxygen rebreathers are severely depth limited due to oxygen toxicity risk, which increases with depth, and the available systems for mixed gas rebreathers were fairly bulky and designed for use with diving helmets. The first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash. During the 1930s and all through World War II, the British, Italians and Germans developed and extensively used oxygen rebreathers to equip the first frogmen.

The breathing apparatus will generally increase dead space by a small but significant amount, and cracking pressure and flow resistance in the demand valve will cause a net work of breathing increase, which will reduce the diver's capacity for other work. Work of breathing and the effect of dead space can be minimised by breathing relatively deeply and slowly. These effects increase with depth, as density and friction increase in proportion to the increase in pressure, with the limiting case where all the diver's available energy may be expended on simply breathing, with none left for other purposes. This would be followed by a buildup in carbon dioxide, causing an urgent feeling of a need to breathe, and if this cycle is not broken, panic and drowning are likely to follow.

It appeared in news images of coalmine rescue squads. In 1908 the apparatus was chosen for use by rescuers from the newly formed Howe Bridge Mines Rescue Station. These gear were used in the London fire brigade from the 1950s till the early to late 1970s as replacing these outdated re-breathers to compressed air units which uses a cylinder strapped to the back of the firefighter and the air fed through a hose to the firefighter's full face mask (this is the current type of breathing apparatus.) Some had a whistle that automatically sounded when its oxygen cylinder pressure became low in use. This feature was introduced following the death, in January 1958, of two London firemen at the fire that occurred at the Smithfield Central Meat Market in central London.

Graph of the breathing resistance of an open-circuit demand regulator. The area of the graph (green) is proportional to the net mechanical work of breathing for a single breathing cycle In the diving industry the performance of breathing apparatus is often referred to as work of breathing. In this context it generally means the work of an average single breath taken through the specified apparatus for given conditions of ambient pressure, underwater environment, flow rate during the breathing cycle, and gas mixture - underwater divers may breathe oxygen-rich breathing gas to reduce the risk of decompression sickness, or gases containing helium to reduce narcotic effects. Helium also has the effect of reducing the work of breathing by reducing density of the mixture, though helium's viscosity is fractionally greater than nitrogen's.

Graph of the breathing resistance of an open-circuit demand regulator. The area of the graph (green) is proportional to the net work of breathing for a single breathing cycle Hydrostatic pressure differences between the interior of the lung and the breathing gas delivery increased breathing gas density due to ambient pressure, and increased flow resistance due to higher breathing rates may all cause increased work of breathing and fatigue of the respiratory muscles. A high work of breathing may be partially compensated by a higher tolerance for carbon dioxide, and can eventually result in respiratory acidosis. Factors which influence the work of breathing of an underwater breathing apparatus include density and viscosity of the gas, flow rates, cracking pressure (the pressure differential required to open the demand valve), and back pressure over exhaust valves.

Commando courses included basic parachutist, diving, small scale raids, demolitions, climbing and roping and unarmed combat. 1 Commando Company held the first diving course in 1957 using a pure oxygen re-breather named the Clearance Divers Breathing Apparatus CDBA borrowed from the Navy Clearance Diving Branch based on training received from the Special Boat Service. In 1957, as the unit already had the designation "1st" within its title, the Army thought it would be a convenient framework on which to re-form the Australian Imperial Force's 1st Battalion. So on 1 December 1957 the unit was re-designated the 1st Infantry Battalion (Commando), keeping this title until 22 August 1966 when the unit was renamed the 1st Battalion, The Royal New South Wales Regiment (Commando), City of Sydney's Own Regiment.

Agnes Milowka Underwater divers are people who take part in underwater diving activities - Underwater diving is practiced as part of an occupation, or for recreation, where the practitioner submerges below the surface of the water or other liquid for a period which may range between seconds to order of a day at a time, either exposed to the ambient pressure or isolated by a pressure resistant suit, to interact with the underwater environment for pleasure, competitive sport, or as a means to reach a work site for profit or in the pursuit of knowledge, and may use no equipment at all, or a wide range of equipment which may include breathing apparatus, environmental protective clothing, aids to vision, communication, propulsion, maneuverability, buoyancy and safety equipment, and tools for the task at hand.

View of fire scene from Nathan Road Two firefighters from Mong Kok Fire Station, Senior Fireman Siu Wing-fong, 46 years old with 24 years' experience, and Fireman Chan Siu-lung, 25 years old with one year of service, died from smoke inhalation on the top floor of the building while trying to reach trapped residents. Survivors reported that the two officers had given them their oxygen breathing apparatus even while continuing to carry the heavy cylinders. One of the two civilian victims was a 77-year-old woman, on the ninth floor, and the other was a female staff member at the nightclub, surnamed Man and aged 39, who had been asleep with colleagues. Her burned body was found in the nightclub after the fire was extinguished.

Improvements in training standards and equipment design and configuration, and increased awareness of the risks of diving, have not eliminated fatal incidents, which occur every year in what is generally a reasonably safe recreational activity. Both categories of diver are usually trained and certified, but recreational diving equipment is typically limited to Self Contained Underwater Breathing Apparatus (Scuba), whereas professional divers may be trained to use a greater variety of diving systems, from Scuba to surface supplied mixed gas and saturation systems. A recreational diver may use some ancillary equipment to enhance the diving experience, but the professional will almost always use tools to perform a specific task. Since the goal of recreational diving is personal enjoyment, a decision to abort a dive, for whatever reason, normally only affects the diver and his companions.

2007-registered Mercedes dual-purpose pump/ladder The dual-purpose ladder (DPL) is the standard fire engine deployed to all 999 emergency calls by the London Fire Brigade. There are 102 DPLs in operation across the city, with 45 in reserve and 25 used for training purposes. The DPL typically carries 13.5 m and/or 9 m ladder extensions, eight 18 m lengths of hose-reel tubing, four 23 m lengths of 45 mm hose, ten 23 m lengths of 70 mm hose, cutting equipment, a portable generator, a lightweight portable pump, water-packs, inflatable airbags, road signs, floodlights, a medical kit, hose ramps, general tools, chemical suits and breathing apparatus. At fire stations with two DPLs, one will be a 'pump' and the other a 'pump ladder', both carrying a short extension ladder and cat ladder for climbing roofs.

Firemen's Memorial (Boston) by John Wilson PPE tackle an aircraft fire during a drill at Dyess Air Force Base in Abilene, Texas To allow protection from the inherent risks of fighting fires, firefighters wear and carry protective and self-rescue equipment at all times. A self-contained breathing apparatus (SCBA) delivers air to the firefighter through a full face mask and is worn to protect against smoke inhalation, toxic fumes, and super heated gases. A special device called a Personal Alert Safety System (PASS) is commonly worn independently or as a part of the SCBA to alert others when a firefighter stops moving for a specified period of time or manually operates the device. The PASS device sounds an alarm that can assist another firefighter (firefighter assist and search team (FAST), or rapid intervention team (RIT), in locating the firefighter in distress.

Classic twin-hose Cousteau-type aqualung Aqua-LungAfter Cousteau himself, who had coined the word, the spelling was originally Aqua-Lung. See Jacques-Yves Cousteau & Frédéric Dumas, Le Monde du silence, Éditions de Paris, Paris, 1953, Dépôt légal 1er Trimestre 1954 - Édition N° 228 – Impression N° 741 (in French) was the first open-circuit, self-contained underwater breathing apparatus (or "scuba") to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a diving regulator,Both regulators—the one from 1860 invented by Benoît Rouquayrol and the twin-hose Cousteau-type invented in 1943 by Gagnan and Cousteau—received, among some others, the name of régulateur (French for "regulator"). For the 1860 régulateur see the page of the Rouquayrol-Denayrouze apparatus in the Musée du Scaphandre website (a diving museum in Espalion, south of France) .

A drawback to the equipment pioneered by Deane and Siebe was the requirement for a constant supply of air pumped from the surface. This restricted the movements and range of the diver and was also potentially hazardous as the supply could get cut off for a number of reasons. Early attempts at creating systems that would allow divers to carry a portable breathing gas source did not succeed, as the compression and storage technology was not advanced enough to allow compressed air to be stored in containers at sufficiently high pressures. By the end of the nineteenth century, two basic templates for scuba, (self-contained underwater breathing apparatus), had emerged; open-circuit scuba where the diver's exhaust is vented directly into the water, and closed-circuit scuba where the diver's unused oxygen is filtered from the carbon dioxide and recirculated.

BIBS mask for oxygen provision in a hyperbaric chamber Sealing to the front of the lower jaw An orinasal mask, oro-nasal mask or oral-nasal mask is a breathing mask that covers the mouth and the nose only. It may be a complete independent item, as an oxygen mask, or on some anaesthetic apparatuses, or it may be fitted as a component inside a fullface mask on underwater breathing apparatus, a gas mask or an industrial respirator to reduce the amount of dead space. It may be designed for its lower edge to seal on the front of the lower jaw or to go under the chin. An orinasal mask may carry a filter for ambient air, or be supplied from a user-carried breathing gas supply or a remote gas supply using a supply hose.

The first phase is fire fighting, which sees recruits learn aircraft crash rescue fire fighting skills, however new recruits also learn skills required for domestic fire fighting, the safe use and control of breathing apparatus, road traffic incidents and various other skills that would be required as would be for the civilian fire service. The second phase of training is Aircraft Handling which sees recruits learning the skills required for the safe movement, take off and landing of aircraft on board Royal Navy ships and at Royal Naval air stations. The training for this role is carried out on a full-size mock-up flight deck known as HMS Siskin (Dummy Deck). HMS Siskin is largely made up to replicate the Invicible-class aircraft carrier but can also be adapted to the roles of smaller ships such as frigates and destroyers.

The book is structured into three parts. The first part describes several anomalous ancient artifacts that turn out to be remnants of modern era items: a part of a pilot's breathing apparatus worshipped for centuries as a Catholic saintly relic, a clearly recognizable trace of a Jeep discovered during archaeological works on Gibraltar, found in the same layer as an early hominid skeleton, and an equally old grenade launcher of a model just introduced in the US Army. William W. Francis, an ambitious officer of the US Navy, becomes convinced that time travel is possible and manages to launch a secret project to develop a technological device able to transfer people and materiel through time. The second part describes the project "Chronotron", the successful implementation of a time machine, which is at first able only to move things into the past.

He added a manual Michelin air pump, the type used to inflate car tyres, to pump air down the tube, and also a clamp for the diver's nose to prevent water entry, and goggles to protect the eyes and permit underwater vision. Air was pumped continuously down the tube and flowed out of the exhaust valve of the mouthpiece, causing the pressure in the mouthpiece to be exactly the same as the external water pressure. The diver could breathe in and out from this stream of air without difficulty. This breathing apparatus was called the Fernez model 1. Fernez demonstrating his diving equipment 1912 During the summer of 1912 Fernez tested his equipment by diving 6 metres deep in the river Seine near Alfortville and remaining immersed for 58 minutes, only being forced to the surface by the cold of the water.

In 1913 he received the gold medal at the Universal Exhibition in Ghent (Belgium) and the silver medal of the Society for the Encouragement of Domestic Industry. Fernez expanded his range of equipment to include respirators for use in mines, and during the first World War (WW1) produced gas masks for men, horses and dogs. Other equipment produced by Fernez's company included: the Fernez model 3 breathing apparatus, for use in underground pipes and galleries (such as mines or sewers) where the tube is extended to 80 metres, charcoal filters against foul gases such as ammonia and sulfur, an oxygen rebreathing apparatus with soda to absorb CO2, a medical oxygen inhaler, and an air circulation helmet for the fire brigade. In 1930 the Fernez company registered a new patent for filter cartridges for gas and dust.

Some early fossils such as the Late Silurian Proscorpius have been classified by paleontologists as scorpions, but described as wholly aquatic as they had gills rather than book lungs or tracheae. Their mouths are also completely under their heads and almost between the first pair of legs, as in the extinct eurypterids and living horseshoe crabs. This presents a difficult choice: classify Proscorpius and other aquatic fossils as something other than scorpions, despite the similarities; accept that "scorpions" are not monophyletic but consist of separate aquatic and terrestrial groups; or treat scorpions as more closely related to eurypterids and possibly horseshoe crabs than to spiders and other arachnids, so that either scorpions are not arachnids or "arachnids" are not monophyletic. Cladistic analyses have recovered Proscorpius within the scorpions, based on reinterpretation of the species' breathing apparatus.

For example, IOM scientists helped develop improved powered helmet respirators following research that showed existing devices to be heavy, cumbersome, uncomfortable and intrusive. In the 1990s, on behalf of the UK fire service, studies were carried out of the physiological and ergonomic impacts of breathing apparatus, fire hoods and protective clothing. The studies on fire hoods showed that, contrary to common belief, they did not affect the ability of firefighters to localise sound. This led to a recommendation by the UK Home Office that all fire fighters should routinely be issued with such hoods, advice which is now followed throughout the UK. The IOM has helped to assess Chemical, Biological, Radiological and Nuclear (CBRN) protective clothing for the Home Office, and has recently assisted London Fire Brigade in the ergonomic assessment for selection of new protective clothing.

Guglielminetti-Drager breathing apparatus (front) Rescue attempts began quickly on the morning of the disaster, but were hampered by the lack of trained mine rescuers in France at that time, and by the scale of the disaster: some two-thirds of the miners in the mine at the time of the explosion perished, while many survivors suffered from the effects of gas inhalation. Expert teams from Paris and from Germany arrived at the scene on 12 March. The first funerals occurred on 13 March, during an unseasonal snowstorm; 15,000 people attended. The funerals were a focus for the anger of the mining communities against the companies which owned the concessions, and the first strikes started the next day in the Courrières area, extending quickly to other areas in the départements of the Pas-de-Calais and the Nord.

The practice of shallow breathing or skip breathing in an attempt to conserve breathing gas should be avoided as it tends to cause a carbon dioxide buildup, which can result in headaches and a reduced capacity to recover from a breathing gas supply emergency. The breathing apparatus will generally increase dead space by a small but significant amount, and cracking pressure and flow resistance in the demand valve will cause a net work of breathing increase, which will reduce the diver's capacity for other work. Work of breathing and the effect of dead space can be minimised by breathing relatively deeply and slowly. These effects increase with depth, as density and friction increase in proportion to the increase in pressure, with the limiting case where all the diver's available energy may be expended on simply breathing, with none left for other purposes.

The apparatus also has to remove the exhaled carbon dioxide, as a buildup of CO2 levels would result in respiratory distress and hypercapnia. The first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash, the system giving a dive duration of up to about three hours. Fleuss tested his device in 1879 by spending an hour submerged in a water tank, then one week later by diving to a depth of in open water, on which occasion he was slightly injured when his assistants abruptly pulled him to the surface.

Those early traditions continue and customarily include a standby diver, and a working diver who is in constant communication with the surface control crew. The sport of scuba diving is rooted in a multitude of small enthusiastic snorkeling and spearfishing clubs that date back to the decades just before and after World War II. In the late 1940s, after the invention of the Aqua- lung by Cousteau and Gagnan, the first retail underwater breathing apparatus for sport was commercially marketed. As the sport expanded through the 1950s, several sporting organisations – notably the Young Men's Christian Association (YMCA) – began scuba training programmes for swimming enthusiasts, thus began the codification of what was believed to be proper practices for the expanding amateur sport of scuba diving. The buddy system was thought to be a useful corollary to the "never swim alone" edicts of the YMCA swimming and lifesaving programmes.

Early testing done by the US Navy was the origin of underwater breathing apparatus simulation testing in the late 1970s. The breathing simulator systems built by Stephen Reimers were bought by the Ministry of Defence in the UK and by some private equipment manufactures like Kirby Morgan Diving Systems, and helped develop European standards in the early 1990s, but the introduction of a complete breathing simulator system by ANSTI Test Systems Ltd in the UK made possible the accurate breathing simulator testing that is the current practice. The computerized ANSTI breathing simulator systems made faster, easier and more accurate testing possible, and are designed for testing in all realistic water temperatures. The system includes precise humidity and exhalation temperature control as well as environmental water temperature control from , facilities for breath by breath CO2 analysis and closed circuit rebreather set point control and scrubber endurance testing.

The years of World War II were decisive for the history of diving. After the armistice of 1940, the family of Simone and Jacques-Yves Cousteau took refuge in Megève, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the same desire to reveal to the general public unknown and inaccessible places — for Cousteau the underwater world and for Ichac the high mountains. The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands in Var, with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche, an engineer of Arts and Measures at the Naval College.

In the Legends continuity, Darth Tenebrous (Rugess Nome) was a male Bith Dark Lord of the Sith with the power of foreseeing the future, including his own death, and the master of both Darth Plagueis and Darth Venamis, the latter of whom he kept secret as it was a violation of the Rule of Two. His public persona was Rugess Tome, a legendary artisanal starship designer with a galaxy-spanning reputation, and he was known for being a scientific genius and master planner, as well as for his breathing apparatus. Tenebrous' secret plan was to possess the Chosen One once he would appear, but he was eventually killed by Plagueis during a mission on the planet Ban'demnic. However, Tenebrous wasn't too surprised at Plagueis's betrayal and instead congratulated him with his dying breath, because his conscience would soon be able to enter his apprentice's body.

Scuba diver in Panama The full scope of recreational diving includes breath-hold diving and surface supplied diving – particularly with lightweight semi-autonomous airline systems such as snuba – and technical diving (including penetration diving), as all of these are sometimes done for recreational purposes, but common usage is mostly for open water scuba diving with limited decompression. Scuba diving implies the use of an autonomous breathing gas supply carried by the diver, the self-contained underwater breathing apparatus which provides the name for this mode of diving. Scuba may be the simpler and more popular open circuit configuration or one of the more complex and expensive closed or semi-closed rebreather arrangements. Rebreathers used for recreational diving are generally designed to require a minimum task loading on the diver and as far as possible to fail safe and give the diver ample warning to bail out to open circuit and abort the dive.

In the U.S. Major Christian J. Lambertsen invented a free-swimming oxygen rebreather. In 1952 he patented a modification of his apparatus, this time named SCUBA, an acronym for "self- contained underwater breathing apparatus," which became the generic English word for autonomous breathing equipment for diving, and later for the activity using the equipment. After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers. The high percentage of oxygen used by these early rebreather systems limited the depth at which they could be used due to the risk of convulsions caused by acute oxygen toxicity. Although a working demand regulator system had been invented in 1864 by Auguste Denayrouze and Benoît Rouquayrol, the first open-circuit scuba system developed in 1925 by Yves Le Prieur in France was a manually adjusted free-flow system with a low endurance, which limited the practical usefulness of the system.

Davis breathing apparatus tested at the submarine escape test tank at HMS Dolphin, Gosport, 14 December 1942 The DSEA rig chiefly addressed the problem of anoxia threatening a person ascending through water, by providing oxygen; and the associated risk of lung over-pressure injury as underwater pressure reduces with reducing depth, which it addressed by managing oxygen pressures. It also provided assistance with buoyancy, both in the ascent and after reaching the surface. The risk of decompression illness due to ascending too fast could be addressed by associated equipment; any other escape requirements, such as means of summoning help once the surface was reached, were not considered. The apparatus itself comprises a rubber breathing/buoyancy bag, which contains a canister of barium hydroxide to scrub exhaled CO2 and, in a pocket at the lower end of the bag, a steel pressure cylinder holding approximately 56 litres of oxygen at a pressure of 120 bar.

The National Fire Protection Association (NFPA) defines the policy that refers to a safety system to protect firefighters, known as rapid intervention crew (RIC) or firefighter assist and search team (FAST), where two or more firefighters enter a building and at least two more remain outside, near the entrance, fully equipped and ready to help in case of emergency. Firefighters enter a building in teams to extinguish the fire and/or make a rescue. When a team enters an IDLH atmosphere (the "two-in"), two more firefighters (the "two-out") stand by at the entrance in full personal protective equipment (to include bunker gear and self-contained breathing apparatus), and ready with rescue tools, in order to rapidly enter the building if the team inside becomes endangered. By some interpretations, the rule requires at least two more firefighters to remain outside, even when the standby team has gone in to find and rescue the first team.

The damage caused by explosions and by the water directed down the pit was severe, and efforts concentrated on building stoppings so that fresh air could be readmitted to the pit. In May, Parry Davies, captain of the Llay Main No. 2 rescue team, accompanied by two inspectors and a Ministry of Mines doctor, entered into the 20's return airway to recover the body of John Lewis of Cefn-y-Bedd, one of the members of the No. 1 team killed in the initial rescue attempts. By July, a party of men using breathing apparatus had proceeded 700 yards beyond the stoppings into the Dennis section as far as the top of the haulage road of the 142's Deep, though they found no trace of any of the missing miners. Within a matter of months, normal ventilation was restored to the Slant section: this work was, to that date, the first ever reopening of a pit by men working in an irrespirable atmosphere.

Both Cripps and Jones suggested the Inspectorate itself was partly culpable for the explosion through its failure to enforce the Regulations: Jones noted the inadequate work of the local and divisional inspectors, Dominy and Charlton, at Gresford in the months leading up to the disaster and Cripps argued the Inspectorate had an interest in turning a blind eye to safety failings. Cripps went so far as to describe Dominy's inspections as "an absolute farce" and commented that it was "pathetic that a person who answers questions like that should be in charge of the inspection of mines in a large area of the country". The inquest was initially adjourned on 14 December 1934, pending reopening of the Dennis section to obtain further evidence. Although recovery teams wearing self-contained breathing apparatus re-entered the sealed pit in May 1935, both government inspectors and officials from the Westminster and United Collieries Group would not allow any further attempts to be made to access the Dennis section.

Diving helmet that belonged to the Senior Chief Navy Diver Nikita Sergeyevich Myshlyaevskiy The exhibition occupies two rooms: the bigger one is devoted to the diving history, the smaller – to the Great Patriotic War, Leningrad Siege, and the Kronstadt military history. The museum houses a wide collection of diving equipment of different times, noteworthy, that all equipment is still operational. The collection comprises several diving helmets including the famous 3-bolt helmet (Russian “УВС-50М”) and 12-bolt coupled helmet. One of the most interesting and attractive exhibits of the 20th century are two surface and submerged diver delivery vessels Proton and Proteus used for sabotage, saboteurs’ weapon, suits of underwater swimmers. Besides, there is ventilated diving equipment, breathing sets of different types and purposes, dive knives, personal divers’ belongings, documents, recovered cannonballs etc. To the display items belong a torpedo firing panel and a diving immersion suit with a self-contained underwater breathing apparatus (Russian “ИДА-59”).

The instructor monitors a trainee practicing diving skills Scuba skills are the skills required to dive safely using self-contained underwater breathing apparatus, (scuba). Most of these skills are relevant to both open circuit and rebreather scuba, and many are also relevant to surface-supplied diving. Those skills which are critical to the safety of the diver may require more practice than is usually provided during training to achieve reliable long-term proficiency Some of the skills are generally accepted by recreational diver certification agencies as necessary for any scuba diver to be considered competent to dive without direct supervision, and others are more advanced, though some diver certification and accreditation organizations may consider some of these to also be essential for minimum acceptable entry level competence. Divers are instructed and assessed on these skills during basic and advanced training, and are expected to remain competent at their level of certification, either by practice or refresher courses.

Halichondria produces the eribulin (Halaven) precursor halichondrin B For many years, traditional Western pharmacognosy focused on the investigation and identification of medically important plants and animals in the terrestrial environment, although many marine organisms were used in Traditional Chinese Medicine. With the development of the open-circuit self-contained underwater breathing apparatus or SCUBA in the 1940s, some chemists turned to more pioneering work looking for new medicines in the marine environment. In the United States, the road has been long for the first FDA approval of a drug directly from the sea, but in 2004, the approval of ziconotide isolated from a marine cone snail has paved the way for other marine-derived compounds moving through clinical trials. With 79% of the earth's surface covered by water, research into the chemistry of marine organisms is relatively unexplored and represents a vast resource for new medicines to combat major diseases such as cancer, AIDS or malaria.

The Second World War separated their team temporarily and Tailliez in particular would take part at the time of the campaign in Syria, with naval action against the Vichy navy. On armistice leave and thus having time, in 1942 they made without breathing apparatus the first French underwater film: Par dix-huit mètres de fond (= "18 meters deep"), and the next year Epaves (= "Wrecks"), this time with the Cousteau-Gagnan aqualung, and with the funds of the Marseilles company of reinflation "Marcellin". In the wartime shortages, to get movie film to make Epaves, Cousteau had to buy up hundreds of unexposed short small-gauge films intended for children's toy cameras, and splice them end-to-end into movie-length reels.The Silent World (book) In 1945, the Gaullist admiral Lemonnier, having viewed this film, entrusted to Tailliez the direction of the G.R.S. (Group of Underwater Research) (which in 1950 became the G.E.R.S. (Group of Studies and Underwater Research), and is now CEPHISMER - CEllule Plongée Humaine et Intervention Sous la MER).

A diver wearing an Ocean Reef full face mask A full-face mask encloses both mouth and nose, which reduces the risk of the diver losing the air supply compared to a half mask and demand valve. Some models require a bailout block to provide alternative breathing gas supply from the umbilical and bailout cylinder, but are not suitable for accepting an alternative air supply from a rescue diver, while a few models accept a secondary demand valve which can be plugged into an accessory port (Draeger, Apeks and Ocean Reef). The unique Kirby Morgan 48 SuperMask has a removable DV pod which can be unclipped to allow the diver to breathe from a standard scuba demand valve with mouthpiece. Despite the improvement in diver safety provided by the more secure attachment of the breathing apparatus to the diver's face, some models of full face mask can fail catastrophically if the faceplate is broken or detached from the skirt, as there is then no way to breathe from the mask.

Training in the characteristics and use of breathing apparatus as relevant to the certification Diver training is the set of processes through which a person learns the necessary and desirable skills to safely dive underwater within the scope of the diver training standard relevant to the specific training programme. Most diver training follows procedures and schedules laid down in the associated training standard, in a formal training programme, and includes relevant foundational knowledge of the underlying theory, including some basic physics, physiology and environmental information, practical skills training in the selection and safe use of the associated equipment in the specified underwater environment, and assessment of the required skills and knowledge deemed necessary by the certification agency to allow the newly certified diver to dive within the specified range of conditions at an acceptable level of risk. Recognition of prior learning is allowed in some training standards. Professional diver certification is generally in terms of a diver training standard published by a national government organisation or department, or an international organisation of which such national bodies are members.

An ascent blackout, or deep water blackout, is a loss of consciousness caused by cerebral hypoxia on ascending from a deep freedive or breath-hold dive, typically of ten metres or more when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it, or from a dive using underwater breathing apparatus using a breathing gas which has too low an oxygen fraction to support consciousness at the surface. Breath-hold victims typically black out close to the surface, sometimes even as they break surface and have been seen to approach the surface without apparent distress only to sink away. Breath-hold victims are usually established practitioners of deep breath-hold diving, are fit, strong swimmers and have not experienced problems before. Blackout by this mechanism may occur even after surfacing from depth and breathing has commenced if the inhaled oxygen has not yet reached the brain and may be referred to as a surface blackout.

Small variations in pressure between the delivered gas and the ambient pressure at the lungs can be tolerated. These can result from the trim of the diver in the water, the position of the diaphragm operating the demand valve, the position of the counterlungs in a rebreather, cracking pressure and flow resistance of the exhaust valve, or intentional overpressure in a full-face mask or helmet, intended to reduce the risk of contaminated water leaking into the breathing apparatus through the exhaust valve. A consistent variation in delivered pressure difference does not affect the work of breathing of the apparatus - the whole graph is shifted up or down without change to the enclosed area - but the effort required for inhalation and exhalation are perceptibly different from normal, and if excessive, may make it difficult or impossible to breathe. A negative static lung loading, where the ambient pressure on the chest is greater than the breathing gas supply pressure at the mouth, can increase work of breathing due to reduced compliance of lung soft tissue.

In the early hours of Friday 13 December 1974, (as it turned out) two fires were deliberately lit in the hotel. Several occupants were aroused by the smell of smoke, and on discovering fire raised the alarm as best they could, before leaving the building. One resident tried to extinguish one of these fires while it was still small, but he did not know how to operate the fire extinguisher which he found. The first of several 999 calls were made to the London Fire Brigade at 03:32 and received by the local fire station, A21, Paddington, who were ordered to the scene along with neighbouring A22, Manchester Square and G26 Belsize, bringing the first attendance of four pumping appliances (two were pumps - P, two were pump escapes - PE, carrying the heavy but stable 50 foot (15m) wheeled escape ladders), a 100 ft (30m) turntable ladder - TL (aerial ladder) and an emergency tender - ET (for the breathing apparatus (BA) sets carried; BA wearing was then still a specialist skill).

Whereas an abbreviation may be any type of shortened form, such as words with the middle omitted (for example, Rd for Road or Dr for Doctor) or the end truncated (as in Prof. for Professor), an acronym – in the broad sense – is formed from the first letter or first few letters of each important word in a phrase (such as AIDS from acquired immuno- deficiency syndrome, and scuba from self-contained underwater breathing apparatus). However, this is a loose rule-of-thumb definition, as some acronyms are built in part from the first letters of word components (morphemes), as in the i and d in immuno-deficiency, or using a letter from the middle or end of a word, or from only a few key words in a long phrase or name, as illustrated in some examples below. Less significant words like in, of, and the are usually dropped (NYT for The New York Times, DMV for Department of Motor Vehicles), but not always (TICA for The International Cat Association, DoJ for Department of Justice).

The inter-stage pressure of surface supplied demand breathing apparatus is controlled manually at the control panel, and does not automatically adjust to the ambient pressure in the way that most scuba first stages do, as this feature is controlled by feedback to the first stage from ambient pressure. This has the effect that the cracking pressure of a surface supplied demand valve will vary slightly with depth, so some manufacturers provide a manual adjustment knob on the side of the demand valve housing to adjust spring pressure on the downstream valve, which controls the cracking pressure. The knob is known to commercial divers as "dial-a-breath". A similar adjustment is provided on some high-end scuba demand valves, to allow the user to manually tune the breathing effort at depth Scuba demand valves which are set to breathe lightly (low cracking pressure, and low work of breathing) may tend to free-flow relatively easily, particularly if the gas flow in the housing has been designed to assist in holding the valve open by reducing the internal pressure.

The key rationale for the integration of the functions is that many rural and remote communities do not have dedicated staffing, resources and infrastructure to sustain immediate 24/7 emergency response. A local ESU may exist to mainly provide emergency training such as CPR/AED, first aid, 1st responder, etc. to citizens, communities, OSHA work site and to marine/boating. This mobile training capability uses a light-duty emergency vehicle that is fully equipped with a basic life support (BLS) responder medical, wildland/urban interface firefighting system, powered hydraulic and air bag rescue systems, self-contained breathing apparatus and protective fire gear and other equipment and, when requested, can support the local emergency response system as a rapid intervention vehicle. A state or local public health Emergency Services Unit manages the Department’s emergency supplies, supporting technologies used during disasters, and helps fulfill the National and state Emergency Support Function (ESF) #8 Health & Medical Services and ESF #6 Mass Care & Sheltering needs of community citizens during a major emergency or disaster.

Second, the book also presented the new medical theories by Thomas Beddoes, that tuberculosis and other lung diseases could be treated by inhalation of "Factitious Airs". Sir Humphry Davy's Researches chemical and philosophical: chiefly concerning nitrous oxide (1800), pages 556 and 557 (right), outlining potential anaesthetic properties of nitrous oxide in relieving pain during surgery The machine to produce "Factitious Airs" had three parts: a furnace to burn the needed material, a vessel with water where the produced gas passed through in a spiral pipe (for impurities to be "washed off"), and finally the gas cylinder with a gasometer where the gas produced, "air", could be tapped into portable air bags (made of airtight oily silk). The breathing apparatus consisted of one of the portable air bags connected with a tube to a mouthpiece. With this new equipment being engineered and produced by 1794, the way was paved for clinical trials, which began in 1798 when Thomas Beddoes established the "Pneumatic Institution for Relieving Diseases by Medical Airs" in Hotwells (Bristol).

Weightman approved the shot-firer to go ahead and deploy his shot which ignited the gas in that area of the mine. Just before 9:00 am, the banksman of the mine noted a cloud of dust rising up No. 4 shaft and Mines rescue were called out. In all, 39 men died in the explosion with all bodies being recovered by 10 September. Identification of the bodies was difficult because of damage to the miners faces; one had to be identified by his belt and trousers because his face was so disfigured. An explosion occurred on 13 December 1927 which killed four men. On 9 February 1928, efforts were made to go in and check on the state of the mine, the 800 miners of the interconnected Wellington Mine had gone back to work on 3 January 1928, but the 1,100 miners at Haig were still unable to return to work. The check of the mine was also used as an effort to recover the body of Harold Horrocks who had not been recovered since the 13 December accident. A body of 24 men entered the mine to assess the damage and various trips back to the surface for sustenance and to re-fill breathing apparatus were undertaken throughout the day and night.
