Hazard identification (GHS)
- Contains gas under pressure; may explode if heated (H280).
- Simple asphyxiant — heavier than air, collects in pits and low or confined spaces and can cause rapid suffocation.
First-aid measures
Inhalation (asphyxiation): remove to fresh air immediately; rescuers must wear self-contained breathing apparatus. Give artificial respiration if not breathing, oxygen if breathing is difficult, and obtain medical attention.
Handling & storage
- Argon is denser than air — ventilate low-lying and confined work areas and check oxygen levels before entry.
- Store cylinders upright, capped, below 52 °C; segregate full and empty cylinders.
- Never strike an arc on a cylinder; keep valves clean and open them slowly.
