Which type of fire extinguisher is effective on electrical fires?

Class C fire extinguishers are specifically designed to be effective on fires that involve electrical equipment. This classification indicates that the extinguisher contains non-conductive agents, making it safe to use on live electrical circuits without the risk of electrical shock. The primary extinguishing agents in Class C extinguishers typically include dry chemical powders, carbon dioxide, or other non-conductive materials.

When dealing with electrical fires, it is crucial to use the appropriate type of extinguisher to prevent further hazards. Class A extinguishers are suitable for ordinary combustible materials, Class B for flammable liquids, and Class K for cooking oils and fats, none of which provide the necessary safety or effectiveness in extinguishing electrical fires. Therefore, using a Class C fire extinguisher is essential in these situations to ensure both safety and efficacy in suppressing the fire.
