Which item is included in Class A fires, as described in the four main classes?

• A. Paper, Wood, Ordinary Combustibles (White Smoke, Ash)
• B. Liquid
• C. Electric
• D. Metals

Answer: (A)

Fires that involve ordinary combustibles like paper and wood are categorized as Class A. These fuels are solid materials that burn to ash, and they often produce light-colored (white) smoke. That’s why paper and wood are classic examples—they’re common solid fuels that leave ash behind as they burn. The other options describe fuels that belong to different classes: liquids fall under Class B, electrical equipment under Class C, and metals under Class D. Those materials burn in ways that require different extinguishing approaches, so they aren’t part of Class A.
