What should be used to extinguish an electrical fire?

The use of a clean agent to extinguish an electrical fire is appropriate because clean agents are non-conductive and effective in smothering the fire without causing damage to electrical equipment. These agents include substances like halon or other halogenated agents, which can interrupt the chemical reaction in a fire and do not leave residue that could harm electronics or sensitive equipment.

In contrast, using water on an electrical fire can create a risk of electrocution, as water conducts electricity. Foam extinguishers are typically designed for flammable liquid fires and may not be effective, or safe, for electrical fires due to their conductive properties. Powder extinguishers can be used for electrical fires, as they are typically non-conductive and effective for various types of fires; however, they may leave a residue that could damage sensitive electrical components. Clean agents are favored specifically for their safety around electrical equipment and minimal cleanup afterwards.
