Which hazard class is represented by a placard illustration showing a flame?

• A. Explosives
• B. Nonflammable Gases
• C. Flammable Solids
• D. Dangerous When Wet

Answer: (C)

A flame on a placard signals a flammable hazard, meaning the material can ignite readily. In hazmat classifications, that flame symbol is used to denote Flammable Solids (Class 4.1), which are solids that can catch fire easily or ignite by friction, heat, or impact, or become flammable under certain conditions. These placards help responders quickly assess ignition risk and plan appropriate precautions. Explosives are shown with an exploding bomb symbol, nonflammable gases with a gas cylinder symbol, and dangerous when wet with a symbol indicating water-reactive properties. Those symbols point to different hazards, not the flammable solids category, so the flame specifically aligns with flammable solids.
