Which is a class "A" fire?

• A. Wood
• B. Electrical
• C. Paper
• D. Gasoline

Answer: (A)

Class A fires involve ordinary combustibles like wood, paper, textiles, and trash. Wood is a classic example because it is a solid fuel that burns with embers and leaves ash. Extinguishing Class A fires focuses on cooling the fuel with water to drop its temperature below its ignition point. Paper is also an ordinary combustible and would be in the same category, but the example here uses wood. Gasoline is a flammable liquid and belongs to Class B. Electrical fires involve energized equipment and require nonconductive extinguishing methods, typically Class C.
