A fire extinguisher bearing the symbols shown would be suitable for extinguishing which types of fires?

• A. Class B, C, and D
• B. Class A, B, and K
• C. Class A, B, and C
• D. Class A, B, C, and D

Answer: (C)

The main idea being tested is how extinguisher ratings map to fire types. If an extinguisher bears symbols for Class A, Class B, and Class C, it means it’s approved for ordinary combustibles (like wood and paper), flammable liquids (like gasoline and solvents), and energized electrical equipment. That combination covers a wide range of common fires, which is why this extinguisher is suitable for those types. It won’t cover Class K fires (cooking oils) or Class D fires (metals), which require different, specialized extinguishing agents.
