What type of fire extinguisher should be used on electrical fires?

Class C fire extinguishers are specifically designed for use on electrical fires. These extinguishers utilize non-conductive agents that can effectively extinguish flames without the risk of conducting electricity, which can create dangerous situations for the user.

Electrical fires can occur in situations where flammable material comes into contact with electrical equipment or wiring, and using the appropriate extinguisher is crucial to ensure safety. Class C extinguishers often contain dry chemical agents like monoammonium phosphate or sodium bicarbonate, giving them the necessary properties to put out fires caused by energized electrical equipment safely.

In contrast, Class A fire extinguishers are designed for ordinary combustibles like wood and paper, Class B extinguishers are meant for flammable liquids, and Class D extinguishers are used for combustible metals. Using the wrong type of extinguisher, such as one designed for Class A or B fires on an electrical fire, can lead to further risks, including the possibility of electrical shock or a more intense fire.
