Hazard Class or Division:
2.2 (NON-FLAMMABLE, NON-POISONOUS GAS)
(but may cause combustibles to ignite) compressed gas, or cryogenic liquid.
Colorless gas; blue liquid. Odorless. Sinks and "boils" in water. Gas
is heavier than air; will collect in low areas.
of welding gases; in oxyhydrogen or oxyacetylene flame for welding metals and
for lighting (calcium light, etc.); oxidizing agent and air-enricher for
combustion, blast furnaces, flash smelters, in metals, iron, steel, copper,
lead, nickel and uranium industries; for feedstock and enrichment purposes;
lifesupporting gas-e.g., for medicinal use or medication to relieve hypoxia,
carbon monoxide poisoning, etc.; constituent of gaseous anesthetics; by divers
for submarine work; in making liquid fuels.
HEALTH & SAFETY INFORMATION
Extremely high concentrations irritate the respiratory tract. May affect the
eyes, central nervous system, lungs. Breathing 50-100% oxygen at normal
pressure, even intermittently over a prolonged period, may cause lung damage.
Contact with liquid may cause frostbite.
of water will vigorously vaporize liquid oxygen. A strong oxidizer; violent
reaction with reducing agents, combustibles, and organic and easily oxidizable
materials; contact may cause fire and explosions. The low temperature may cause
brittleness on contact with some materials.

Point: Not flammable but supports combustion, and may cause combustible to
victims to fresh air. Call emergency medical care. Apply artificial respiration
victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. Clothing frozen to the skin should
thawed before being removed. In case of contact with liquefied gas, thaw
frosted parts with lukewarm water. Keep victim warm and quiet. Ensure that
medical personnel are aware of the material(s) involved, and take precautions
to protect themselves.
