What type of fire extinguisher is suitable for electrical fires?

Class C fire extinguishers are specifically designed for use on electrical fires. These extinguishers utilize non-conductive agents to safely put out fires involving energized electrical equipment such as wiring, appliances, circuit breakers, and power tools. The key characteristic of Class C extinguishers is their ability to extinguish flames without allowing the operator to become exposed to the risk of electric shock.

Using the wrong type of extinguisher can be dangerous. For example, Class A extinguishers are suited for ordinary combustibles like wood and paper, which could potentially create a hazardous situation if used on electrical fires due to their conductive properties. Class B extinguishers tackle flammable liquids but are not appropriate for electrical fires, as they may allow electric currents to flow back towards the user. Meanwhile, Class D extinguishers are designed for combustible metals and are irrelevant in the context of electrical fires. Thus, the Class C fire extinguisher is the safest and most effective choice for putting out electrical fires.
