AAFCS HNFS Practice Exam – Practice Test Questions & Study Guide

The recommended type of fire extinguisher for putting out electrical fires is the Class C extinguisher. Class C extinguishers are specifically designed for fires that involve electrical equipment, such as appliances, wiring, and circuit breakers. The fire extinguishing agents used in Class C extinguishers are non-conductive, which allows them to safely put out fires without the risk of electrocution.

On the other hand, Class A extinguishers are meant for ordinary combustible materials like wood and paper, Class B extinguishers are for flammable liquids, and Class D extinguishers are used for combustible metals. Using an extinguisher that is not designed for electrical fires could be dangerous, as it may conduct electricity or not be effective at smothering the flames. This emphasizes the importance of selecting the right type of extinguisher based on the nature of the fire.
