Which type of fire extinguisher is suitable for electrical fires?

Class C fire extinguishers are specifically designed for fires involving energized electrical equipment. These extinguishers typically use non-conductive agents, such as carbon dioxide (CO2) or dry chemical powders, to safely extinguish flames without the danger of conducting electricity. This makes them ideal for situations where electrical hazards are present, as using water or other conductive agents can pose significant safety risks by increasing the chance of electrocution.

The other types of extinguishers are not suitable for electrical fires. Class A extinguishers are meant for ordinary combustibles like wood and paper, Class B extinguishers are used for flammable liquids such as gasoline, and Class K extinguishers are specifically designed for cooking oils and fats. Utilizing the wrong extinguisher type can exacerbate the fire or create dangerous situations, highlighting the importance of selecting the correct extinguisher for the specific fire hazard involved.
