Which extinguisher type is appropriate for electrical fires?

• A. Type A
• B. Type B
• C. Type C
• D. Type D

Answer: (C)

Electrical fires require an extinguisher with a non-conductive extinguishing agent and a design safe for live electrical equipment. An extinguisher intended for electrical fires uses agents like carbon dioxide or dry chemical powder that won’t conduct electricity, allowing you to suppress the flame without risking electric shock or further damage. Extinguishers meant for ordinary combustibles (wood, paper, cloth) or for flammable liquids rely on water-based or conductive agents, which can energize circuits or spread the fire, so they’re not appropriate for energized electrical equipment. If it’s safe to do so, shut off the power before attacking the fire, then aim at the base of the flames and sweep.
