Oxygen (02) U.S.P.
Cylinder Color: Green
02- This colorless, odorless gas makes up about one-fifth of the earth’s atmosphere (20.99% by volume). Oxygen is not flammable, but it causes combustible materials to burn vigorously. Never permit oil, grease or other combustibles to come in contact with pure oxygen or associated equipment.
Major Hazards: Vigorously Accelerates Combustion and High Pressure
Exposure Limit: None
Fire Potential: Highly Oxidizing
Odor: None
Mol. Wt.: 32.00
Sp. Gr. (Air = 1) 70° F (21° C): 1.105
Critical Temperature: -181.1° F (-118° C)
Critical Pressure: 737.1 psia (51.8 kg/cm2abs)
Specific Volume: 12.1 ft3/lb at 70°F (0.75 m3/kg at 15° C)
CAS Registry No.: 7782-44-7
D.O.T. Description: Oxygen, Compressed, 2.2, UN1072
Oxygen, Refrigerated Liquid, 2.2, UN1073
Medical Applications: Used in first aid treatment of emergencies such as suffocation and heart attacks, in the treatment of patients with respiratory disorders, in anesthesia and in hyperbaric oxygen chambers for treatment of carbon monoxide poisoning, gas gangrene and other specialized oxygen therapies.
