An example of a Class A fire would be

• A. Electrical
• B. Wood Burning
• C. Gasoline Spill
• D. Solvent

Answer: (B)

Fire classifying is about the fuel involved. Class A fires involve ordinary combustibles that burn as solids and leave ash, like wood, paper, or cloth. Wood burning is a classic example because it’s a solid fuel that forms ash and is effectively cooled and extinguished with water, stopping the heat needed to sustain the flame.

The other options don’t fit Class A: electrical fires involve energized equipment and are handled as a different class due to the electrical hazard; gasoline spills and solvents are flammable liquids, which fall under Class B and are extinguished with methods suitable for liquids (foam, dry chemical, or smothering agents rather than plain water).
