Which type of fire extinguisher is suitable for electrical fires?

A Class C fire extinguisher is specifically designed for electrical fires. This type of extinguisher contains non-conductive agents which safely suppress flames originating from electrical equipment, wiring, and appliances. Electrical fires can occur when faulty wiring, overloaded circuits, or malfunctioning devices ignite, and using a traditional water-based extinguisher could pose a serious electrocution hazard.

Class C extinguishers often utilize agents such as dry chemical powders or carbon dioxide that do not conduct electricity, making them suitable for treating fires involving live electrical equipment. It is important to ensure that the extinguisher employed does not pose a hazard by introducing water or other conductive materials in such situations.

In contrast, Class A extinguishers are meant for ordinary combustibles like wood or paper, while Class B extinguishers are intended for flammable liquids or gases. Class D extinguishers are specifically for combustible metals, which do not correlate with electrical fires. Hence, the Class C extinguisher is the appropriate choice for any situation involving electrical fires.
