The inhalation hazard placard is best described as featuring which symbol?

• A. Skull and crossbones
• B. Flame
• C. Radiation symbol
• D. Biohazard symbol

Answer: (A)

Inhalation hazard placards are meant to warn that a substance is acutely toxic when breathed. The symbol that best communicates this risk is the skull and crossbones, a long-standing warning for poisons and toxic substances. The other symbols point to different hazards: a flame signals flammability, the radiation symbol indicates radioactive materials, and the biohazard symbol marks biological hazards. None of those convey inhalation toxicity as clearly as the skull and crossbones, which is why it’s the correct marker for inhalation hazards. When you see it, treat the substance as something that can harm you through breathing and use appropriate respiratory protection and ventilation.
