What type of extinguisher should be used on electrical fires?

Using a Class C extinguisher on electrical fires is essential because it is specifically designed to handle fires involving energized electrical equipment. These types of extinguishers typically use non-conductive agents, such as carbon dioxide or dry chemical compounds, which effectively extinguish the flames without conducting electricity, minimizing the risk of shock to the user.

Class A extinguishers are intended for ordinary combustible materials such as wood or paper, while Class B extinguishers are meant for flammable liquids and gases. Class D extinguishers are used for combustible metals, and are not suitable for electrical fires. Therefore, the Class C extinguisher is the appropriate choice when addressing fires that involve electrical sources.
