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 ...
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. Alternative sign. Division 2.2 Toxic gases – Gases which:

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]
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.
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
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 ...
The compressor and particularly the compressor oil, must be suitable for this service. If the oxygen fraction is less than 40%, some countries do not require the cylinder and valve to be cleaned for oxygen service. Mixing by mass fraction: oxygen is added to a partially full cylinder that is accurately weighed until the required mix is achieved.
