Which class of fire occurs in flammable liquids?

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

Answer: (B)

Fires are categorized by the fuel involved. Flammable liquids burn as a vapor that forms a flame over the surface of the liquid, which is classified as Class B. This includes gasoline, kerosene, solvents, and oils. To suppress these fires, the goal is to remove or isolate the fuel and cool the liquid, using agents like foam, dry chemical powders, or carbon dioxide. Water is usually avoided because it can spread the liquid and spread the fire rather than extinguish it. In contrast, Class A fires involve ordinary combustibles like wood and paper, Class C fires involve energized electrical equipment, and Class D fires involve combustible metals.
