Which class of fire extinguishers is generally used for electrical fires?

Fire extinguishers are categorized into different classes based on the types of fires they are designed to combat. The classification system helps ensure that the correct extinguisher is used for specific fire hazards, which is crucial for safety.

The correct answer is Class C, which is specifically intended for electrical fires. These types of fires occur when electrical equipment or wiring malfunctions, leading to combustion. Class C extinguishers contain agents that are non-conductive, making them safe to use on live electrical equipment. Using water or other conductive extinguishing agents on electrical fires can pose a severe risk of electrical shock to the user.

In contrast, Class A extinguishers are suitable for ordinary combustibles such as wood, paper, and textiles, while Class B extinguishers are used for flammable liquids and gases. Class D extinguishers are intended for combustible metals, which are not relevant when addressing electrical fires. Thus, using the appropriate class of extinguisher ensures effective fire control while minimizing risk to the individual using it.
