First Aid Measures

Ingestion

Unlikely route of exposure - because oxygen is a gas at ambient temperatures, ingestion is an unlikely route of exposure.

Inhalation

In all but the most severe cases (pneumonia), recovery is rapid after reduction of oxygen pressure; supportive treatment should include immediate sedation, anticonvulsive therapy if needed, and rest.

Skin

Treat frostbite; soak in lukewarm water.

Eyes

Treat frostbite burns.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Vapors may cause dizziness or asphyxiation without warning.

Skin

Direct contact with the escaping compressed gas or liquid oxygen may cause frostbite injury to the skin.

Eyes

Vision loss, myopia, nuclear cataracts, retrolental fibroplasia, and ocular frostbite injury may occur under various conditions of oxygen exposure. Sinus mucosal inflammation, and pharyngeal edema may occur with oxygen administration.

Ingestion

Necrotizing enterocolitis in premature neonates may be, at least partially, caused by oxygen-generated free radicals.

Hazards

Some may react explosively with fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Vapors from liquefied gas are initially heavier than air and spread along ground. Runoff may create fire or explosion hazard. Containers may explode when heated. Ruptured cylinders may rocket.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate protective gloves, clothing and goggles. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Significant dermal exposure to the escaping compressed gas or liquid oxygen may cause reduced body temperature. Seizures - central nervous system involvement in hyperbaric situations may pose a significant threat to safety.

Fire Fighting Measures

Fire Fighting

Dangerously explosive. Cool all affected containers with flooding quantities of water. Do not use water on material itself. Apply water from as far a distance as possible.

Fire Potential

Substance does not burn but will support combustion.

More
Less

Accidental Release Measures

Small spills/leaks

Keep sparks, flames, and other sources of ignition away. Attempt to stop leak if without undue personnel hazard. Do not use water on material itself.
