An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high speed. Tanks in this state are capable of breaking through a brick wall. [19]
Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...
This is a big advantage in mobile emergencies. The option to fill standard oxygen cylinders (e.g., 50 L at 200 bar = 10,000 L each) with high-pressure boosters, to ensure automatic failover to previously filled reserve cylinders and to ensure the oxygen supply chain, e.g., in case of power failure, is given with those systems.
The cylinders used were dural light-alloy cylinders holding 800 litres or RAF steel wire-wound cylinders holding 1,400 litres of oxygen (both at 3,300 p.s.i.; 227.5 bar or 22.75 MPa). The expedition had 8 closed-circuit and 12 open-circuit sets; the open-circuit set used 1 RAF cylinder or 1, 2 or 3 dural cylinders; with total set weight 28 lb ...
The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.
The Vika oxygen generating system, used on Mir and later the International Space Station under the NASA designation Solid Fuel Oxygen Generator (SFOG) is based on lithium perchlorate, which releases about 60% of its weight in oxygen. Of all the perchlorates, lithium perchlorate has both the highest oxygen to weight and oxygen to volume ratio ...
are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere; or; are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does; or; do not come under the other divisions.
