Hazard identification (GHS)
- May cause or intensify fire; oxidiser (H270) — supports combustion like oxygen.
- Contains gas under pressure; may explode if heated (H280).
- May cause drowsiness or dizziness by inhalation; asphyxiant at high concentration.
First-aid measures
Inhalation: remove to fresh air; give oxygen or artificial respiration if needed; keep warm and at rest; get medical attention.
Handling & storage
- Keep away from oils, greases and combustibles — nitrous oxide supports combustion.
- Store cylinders upright, capped, below 52 °C away from flammables; use oxidiser-compatible regulators.
- Ensure ventilation; prevent unauthorised recreational access (controlled abuse risk).
Physical & chemical properties
Stability & reactivity
Stable at ambient conditions; supports combustion and decomposes to nitrogen and oxygen above ~575 °C. Incompatible with combustibles and reducing agents.
Transport information
