Which symbol corresponds to Compressed Gas?

• A. Radioactive
• B. Compressed Gas
• C. Flammable material
• D. Oxidizing

Answer: (B)

Hazard symbols communicate what kind of danger a substance poses. The symbol for compressed gas is the gas cylinder icon: a vertical cylinder that represents gas stored under pressure. This warns that contents are under high pressure and can be dangerous if the container is damaged or released suddenly. The other symbols depict different hazards: the trefoil for radioactive materials, a flame for flammable materials, and a flame over a circle for oxidizing materials. So the cylinder symbol is the correct one for compressed gas.
