A multipurpose extinguisher that can be used on liquids, gases, or ordinary combustibles is labeled which of the following?

• A. BC
• B. B
• C. ABC
• D. K

Answer: (C)

Understanding fire extinguisher classifications helps you pick the right tool for different fire types. A multipurpose extinguisher labeled ABC is designed for Class A fires (ordinary combustibles like wood and paper), Class B fires (flammable liquids, and often including gases in practice), and Class C fires (electrical equipment). Because the scenario involves liquids, gases, and ordinary combustibles, you need a extinguisher that covers all three categories, which ABC does. The other labels don’t cover all three—one misses ordinary combustibles, another misses electrical fires, and another is limited to cooking fats—so the ABC label is the best fit.
