Which hazard class is indicated by a placard design used for corrosive materials?

• A. Explosives
• B. Oxidizers
• C. Flammable Solids
• D. Corrosive Materials

Answer: (D)

Hazardous materials placards communicate the type of danger at a glance. The design used for corrosive materials features a pictogram that shows liquid pouring onto a hand and a surface, signaling that contact can cause severe skin burns and damage equipment. This specific symbol is what distinguishes corrosives from other hazards, making it the correct identification. The other designs point to different dangers—an explosion motif for explosives, a flame over a circle for oxidizers, and a flame for flammable solids—so they don’t represent corrosive materials.
