Which class of fire extinguisher is used to put out an electrical fire?

The correct answer is related to the classification of fire extinguishers based on the types of fires they are designed to extinguish. A fire classified as "C" specifically deals with electrical fires. This classification indicates that the extinguisher is safe to use on fires that involve electrical equipment, such as appliances, wiring, and circuit breakers, without the risk of conducting electricity and causing additional hazards.

Choosing a fire extinguisher labeled for electrical use is crucial because using an inappropriate type could result in severe injuries or further equipment damage. For instance, using a water-based extinguisher on an electrical fire would be particularly dangerous, as water is a conductor of electricity. Therefore, it's essential to use a "C" class extinguisher, which often contains non-conductive agents like foam, dry chemical, or carbon dioxide to effectively and safely combat these types of fires.
