Which type of fire extinguisher is appropriate for use on electrical fires?

The appropriate type of fire extinguisher for use on electrical fires is the Class C extinguisher. Class C extinguishers are specifically designed to tackle fires involving electrical equipment, such as wiring, circuit breakers, and appliances. The extinguishing agents used in Class C extinguishers are non-conductive, preventing the risk of electrical shock when attempting to extinguish the fire.

It's vital to use the correct class of extinguisher because using the wrong type can exacerbate the situation. For instance, a Class A extinguisher, which is intended for ordinary combustible materials like wood and paper, can be dangerous on electrical fires due to the potential for conducting electricity, leading to shock hazards or further fire escalation. Similarly, Class B extinguishers are designed for flammable liquids, and Class D extinguishers are meant for combustible metals, making them unsuitable for electrical fires. The effectiveness and safety of handling electrical fires rely on using the designated Class C extinguisher.
