Hazard identification (GHS)
- May cause or intensify fire; strong oxidiser (H270).
- Contains gas under pressure; may explode if heated (H280).
- Vigorously accelerates combustion; materials that do not normally burn may ignite in oxygen-enriched air.
First-aid measures
Inhalation of pure product: remove to fresh air; get medical attention if effects persist. Oxygen enrichment of clothing is a serious fire risk — air out saturated clothing away from ignition sources before returning to a normal atmosphere.
Handling & storage
- Keep oil, grease and all combustibles rigorously away from oxygen equipment — they ignite violently in oxygen.
- Store cylinders upright, capped, below 52 °C, away from flammables and fuel gases (min 6 m or fire wall).
- Use only oxygen-clean, oxygen-compatible regulators, valves and hoses; never lubricate fittings.
- Open valves slowly to avoid adiabatic ignition.
Physical & chemical properties
Stability & reactivity
Stable. Powerful oxidiser — incompatible with oils, greases, hydrocarbons and all combustible/flammable materials. No hazardous decomposition products.
Transport information
Oxygen, compressed — Class 2.2 (5.1), UN 1072, Label: Non-flammable gas / Oxidiser.
