Which type of fire extinguisher is suitable for electrical equipment?

Fire extinguishers are classified based on the types of fires they are designed to combat. For electrical equipment, the correct answer is a Class C fire extinguisher. This classification is specifically designed for fires involving electrical equipment such as appliances, wiring, and circuit breakers.

Class C fire extinguishers typically use non-conductive agents, which prevent the risk of electrical shock while effectively extinguishing the fire. Common extinguishing agents for Class C fire extinguishers can include dry chemical powders or carbon dioxide, which do not conduct electricity and thus are safe to use on live electrical fires. Using other types of extinguishers, like those suited for ordinary combustibles or flammable liquids, could pose serious risks, as they may conduct electricity and cause further hazards.

Understanding the classifications of fire extinguishers is essential for ensuring safety during fire emergencies, particularly in environments with a significant presence of electrical devices or systems.
