Which class of fire extinguisher is recommended for an electrical fire?

The recommended class of fire extinguisher for an electrical fire is Class C. This type of extinguisher is specifically designed to handle fires that involve electrical equipment and appliances. The extinguishing agents used in Class C extinguishers do not conduct electricity, making them safe to use on electrical fires without the risk of electric shock.

In contrast, other classes of extinguishers are tailored for different types of fires. Class A is suitable for ordinary combustibles like wood and paper, Class B is used for flammable liquids and gases, and Class D is intended for fires involving combustible metals. Using the wrong type of extinguisher, especially on an electrical fire, can exacerbate the situation or lead to dangerous circumstances, such as the risk of electrocution. Therefore, Class C is the best choice for safely extinguishing electrical fires.
