How Oxygen Cylinder Works?

An oxygen Cylinder is a storage container for oxygen, which is stored under pressure in gas cylinders or as liquid oxygen in a cryogenic storage tank. Oxygen Cylinder are used to store gas for medical use in medical facilities and at home.

Breathing oxygen is supplied to users from the storage Cylinder using the following methods: oxygen mask, nasal cannula, full-face scuba mask, oxygen Cylinder , and hyperbaric oxygen chamber.

Contrary to popular belief, scuba divers rarely carry oxygen Cylinders . The vast majority of divers breathe air or nitrox stored in a scuba Cylinder. A small minority breathe heliox, trimix,  and other exotic gases. Some of them can carry pure oxygen for accelerated decompression or as part of a rebreather. Some shallow divers, particularly Navy divers, use, or have in the past used, oxygen rebreathers.

Oxygen is rarely maintained at pressures above 200 bar / 3000 psi due to high temperature fire hazards caused by adiabatic heating as the gas changes pressure as it flows from one vessel to another.

All equipment that comes in contact with high-pressure oxygen must be “oxygen clean” and “oxygen compatible” to reduce the risk of fire. “Oxygen clean” means the removal of all substances that could act as an ignition source. “Oxygen Compatible” means that the internal components should not readily burn or decompose in a high pressure oxygen environment.

Some countries have legal and insurance requirements or restrictions on the use, storage and transportation of pure oxygen. Oxygen Cylinders are typically stored in well-ventilated locations away from potential sources of fire and crowds.
