Which symbol is labeled Explosion Hazard?

• A. Harmful or Fatal
• B. Explosion Hazard
• C. Biohazardous/Infectious
• D. Corrosive

Answer: (B)

Pictograms on hazard labels communicate specific risks at a glance, and the symbol with an exploding bomb is used to warn about an Explosion Hazard. It signals that the material or device could detonate or explode under conditions like impact, heat, friction, or shock, so you handle it with extreme caution and follow storage and handling instructions carefully. The skull-and-crossbones symbol warns of harmful or toxic effects, the biohazard symbol marks infectious or biohazardous materials, and the corrosive symbol indicates substances that can damage skin or metals. None of those indicate an explosion risk.
