Which type of fire extinguisher is suitable for electrical fires?

Class C fire extinguishers are specifically designed for use on electrical fires. This classification is critical because electrical fires can be caused by live electrical equipment or wiring, and using the wrong type of extinguisher can create a more hazardous situation. Class C extinguishers typically use non-conductive agents, such as carbon dioxide or dry chemical powders, which can extinguish flames without conducting electricity.

Class A fire extinguishers are suited for ordinary combustibles like wood and paper, while Class B extinguishers are intended for flammable liquids. Class D extinguishers are used for fires involving combustible metals. Therefore, while each of these types serves a specific purpose, Class C extinguishers are the only ones that are safe and effective for addressing electrical fires.
