Which type of extinguishing agent should be used on electrical fires?

The use of a Class C fire extinguisher on electrical fires is appropriate because it contains non-conductive agents, which are specifically designed to be effective against fires involving energized electrical equipment. Class C extinguishers typically use carbon dioxide (CO2) or dry chemical agents that do not conduct electricity, thus minimizing the risk of electrocution or further electrical hazards.

Using water, which is conductive, could create a dangerous situation by allowing electricity to travel through the water, potentially causing shock or even worsening the fire. A Class A fire extinguisher, which is effective on ordinary combustibles like wood or paper, and a Class B fire extinguisher, used for flammable liquids, are not suitable for use on electrical fires as they do not address the specific risks posed by live electrical equipment.
