Which type of fire extinguisher is suitable for electrical fires?

The choice of a Class C fire extinguisher for electrical fires is appropriate because these extinguishers are specifically designed to handle fires involving electrical equipment. Class C extinguishers contain non-conductive materials, such as carbon dioxide or dry chemicals, which allow them to safely extinguish flames without the risk of electric shock. Using a Class C extinguisher ensures that while putting out the fire, the extinguishing agent will not conduct electricity, thereby reducing the danger to the user and preventing further hazards related to the electrical source.

In contrast, Class A extinguishers are meant for ordinary combustibles like wood and paper, Class B extinguishers target flammable liquids and gases, and Class D extinguishers are used for combustible metals. Therefore, using extinguishers designated for different fire classes on electrical fires can be dangerous and potentially ineffective.
