What type of fire extinguisher is used for electrical fires?

The correct choice for combating electrical fires is a Class C fire extinguisher. Class C extinguishers are specifically designed to put out fires involving energized electrical equipment. The agents used in these extinguishers, such as carbon dioxide or dry chemical agents, do not conduct electricity, which is crucial for safely extinguishing flames while minimizing the risk of electric shock.

Class A extinguishers are meant for ordinary combustibles like wood and paper, while Class B extinguishers focus on flammable liquids and gases. Class D extinguishers are used for combustible metals. Using the wrong type of extinguisher on an electrical fire could lead to dangerous situations, potentially causing the fire to spread or resulting in electrocution. Therefore, it is essential to use a Class C fire extinguisher for any fire involving electric sources to ensure both safety and effectiveness.
