Which DOT hazard class includes flammable solids, and give an example?

• A. Class 3 Flammable liquids; Example: Gasoline.
• B. Class 2 Gases; Example: Propane.
• C. Class 4 Flammable solids; Example: Matches.
• D. Class 8 Corrosives; Example: Sulfuric acid.

Answer: (C)

Hazard classes group materials by the type of danger they pose, and flammable solids have their own category because they can ignite as a solid or by friction, heat, or chemical action. The class that covers flammable solids is Class 4, with matches as a classic example since they ignite from friction when struck. For reference, gasoline is a flammable liquid, propane is a flammable gas, and sulfuric acid is a corrosive.
