Which fire extinguisher classification covers electrical fires?

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

Answer: (C)

Electrical fires need a extinguisher rated for energized equipment. Class C is designed for fires involving electrical equipment, using non-conductive extinguishing agents so you can apply it without creating a shock risk. Water and other conductive solutions are avoided on electrical fires, which is why this classification is the best fit. Other classifications address different fuels—ordinary combustibles like wood and paper, metals, or cooking fats—and don’t apply to electrical equipment, making them unsuitable for this scenario. If safe to do so, shut off the power first and then use the appropriate extinguisher for the situation.
