Measured properties
- Appearance
- Argon appears as a colorless odorless noncombustible gas. Heavier than air and can asphyxiate by displacement of air. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. If liquefied, contact of the very cold liquid with water may cause violent boiling. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Contact · Argon, refrigerated liquid (cryogenic liquid) appears as a colorless noncombustible liquid. Heavier than air. Contact may cause frostbite. May cause asphyxiation by displacement of air. Prolonged exposure to fire or intense heat may cause the container to rupture violently and rocket.
