Which type of extinguisher should be used on electrical fires?

The appropriate choice for extinguishing electrical fires is a Class C extinguisher. Class C fire extinguishers are specifically designed for use on fires involving energized electrical equipment, such as wiring, circuit breakers, and appliances. These extinguishers typically use non-conductive agents, which prevent the risk of electric shock while effectively suppressing the flames.

It is crucial to use a Class C extinguisher on electrical fires to avoid inadvertently causing additional hazards. Other types of extinguishers, such as those designed for flammable liquids (Class B) or ordinary combustibles (Class A), are not suitable for electrical fires due to the potential for electrical shock or further igniting the electrical source.
