Gaseous technical oxygen in cylinders is a product obtained from atmospheric air by deep cooling (cryogenic method) or by water electrolysis.
Gaseous technical oxygen in cylinders is used for welding and surfacing of non-ferrous metals, light alloys, and for intensifying metallurgical processes.

GOST: 5583-78
HS Code: 2804400000
Annual capacity: 2 455 200 m3 tons

Chemical formula: O₂

Technical oxygen is used in:
• Medicine
• Metal welding
• Chemical industry
• Rocket fuel
• Food industry

The oxidizers for this type of fuel are liquid oxygen, hydrogen peroxide, nitric acid, and other oxygen-rich compounds.
The most powerful oxidizer for rocket fuel is a mixture of liquid oxygen and liquid ozone.

Oxygen is used for respiratory disorders, treatment of asthma, prevention of hypoxia, etc.
It is also applied not only for pulmonary and cardiovascular diseases, but is effective for severe conditions such as gangrene, thrombophlebitis, elephantiasis, and trophic ulcers.

Oxygen is registered as a food additive E948.

Oxygen-enriched air makes many technological processes more effective and faster.
Thermal power engineering still relies on oxidation-based processes. An example is converting pig iron into steel — oxygen improves steel quality by removing excess carbon.

• Oxygen is essential for the production of many substances, as well as for the gasification of oil, coal, and fuel oil.
• Liquid oxygen can be used in the production of explosives. For example, any porous material saturated with liquid oxygen becomes an explosive; such materials are known as oxyliquites and can replace dynamite if needed.
• Gaseous oxygen is used for glass blowing and in laboratory research. It is also used to intensify metallurgical processes.

Safety requirements:
Oxygen is a colorless, odorless, non-flammable gas, but it supports combustion and oxidation.
Pure oxygen is not explosive, but in the presence of organic substances there is a risk of ignition (explosion).
Oxygen is not toxic; however, prolonged inhalation of pure oxygen is harmful to the human body.
According to its health impact, it belongs to hazard class 4.
