Oxygen tank

Oxygen tank

An oxygen tank is a storage vessel for oxygen, which is either held under pressure in gas cylinders or as liquid oxygen in a cryogenic storage tank.


Oxygen tanks are used to store gas for:

Breathing oxygen is delivered from the storage tank to the users by use of the following methods: oxygen mask, nasal cannula, full face diving mask, oxygen tent, and hyperbaric oxygen chamber.

Contrary to popular belief scuba divers very rarely carry oxygen tanks. The vast majority of divers breathe air or nitrox stored in a diving cylinder. A small minority breathe trimix, heliox or other exotic gases. Some of these may carry pure oxygen for accelerated decompression or as a component of a rebreather. Some shallow divers, particularly naval divers, use oxygen rebreathers or have done so historically.

As liquid oxygen at atmospheric pressure boils at -183°C / -297°F a liquid oxygen tank must store the oxygen below that temperature and be a good thermal insulator.

Oxygen is rarely held at pressures higher than 200 bar / 3000 psi due to the risks of fire triggered by high temperatures caused by adiabatic heating when the gas changes pressure when moving from one vessel to another.

All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible" to reduce the risk of fire.[1][2] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible" means that internal components must not burn readily or degrade easily in a high pressure oxygen environment.

In some countries there are legal and insurance requirements and restrictions on the use, storage and transport of pure oxygen. Oxygen tanks are normally stored in well ventilated locations, far from potential sources of fire and concentrations of people.
