Which fire class is associated with solids such as wood and cloth?

• A. Class B
• B. Class C
• C. Class A
• D. Class D

Answer: (C)

Fire classifications group fires by the type of fuel involved. Solids such as wood, paper, textiles, and cloth are categorized as ordinary combustibles, which are addressed as Class A fires. These materials burn and leave ash, and the cooling effect of water or similar agents is effective because it removes the heat that keeps the solid fuel burning. Other classes cover different fuels: liquids produce Class B fires, energized electrical equipment creates Class C fires, and certain metallic fuels form Class D fires.
