What is the hazard class represented by the placard illustration?

• A. Explosives
• B. Oxidizers
• C. Flammable Solids
• D. Poison Gas

Answer: (C)

The symbol on a placard tells you the hazard type, and the accompanying markings identify the exact category. A flame indicates flammability, but you need the marking that specifies the class. In this illustration the flame symbol is paired with markings that designate Flammable Solids, meaning the material is a solid that can ignite readily or burn vigorously. This is different from oxidizers, which use a different symbol showing an oxidizing action, and from Poison Gas, which uses a toxic/inhalation hazard symbol. So the placard’s combination of flame plus its specific marking identifies this as Flammable Solids.
