Which class of fires are ordinary combustibles such as paper and wood associated with?

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

Answer: (A)

The idea is to classify fires by the fuel involved, which guides how you fight them. Ordinary combustibles like paper and wood fall into the class that includes fuels that burn to ash and are commonly found in homes and workplaces. This class is best addressed with water-based extinguishing methods because water cools the material, lowering its temperature and halting the combustion process. Examples in this category include paper, wood, cloth, and ordinary trash. The other classifications refer to different fuels: flammable liquids such as gasoline, energized electrical equipment, and combustible metals, each needing different extinguishing agents and tactics. So, ordinary combustibles associated with fires are linked to the class that covers paper and wood.
