Explosive hazard placard color is which?

Explosive hazard placard color is which?

• A. White
• B. Red
• C. Yellow
• D. Orange

Answer: (D)

Color coding on hazard placards communicates hazard class. Explosives are Class 1, and the placard used for this class is orange. This orange color is chosen to stand out and alert responders and handlers to the risk of explosion, prompting strict precautions and separation. Other hazard classes use different colors—red for flammable liquids, yellow for oxidizers or reactive hazards, and white sections for special hazards—so orange uniquely identifies explosive materials. That makes orange the correct color.
