Which fire extinguisher type is suitable for electrical fires?

Carbon dioxide extinguishers are suitable for electrical fires because they work by displacing oxygen in the vicinity of the fire, which is necessary for combustion. When CO2 is released, it envelops the flames and effectively smothers the fire without leaving any residue, making it ideal for use on electrical equipment.

In the context of electrical fires, using water-based extinguishers can be extremely dangerous due to the risk of electrocution. Water is a conductor of electricity and can create a direct path for electrical current. Similarly, foam extinguishers are generally not appropriate for electrical fires, as they also carry a risk of conducting electricity. Dust extinguishers may be used in some cases but are typically not preferred for electrical fires compared to carbon dioxide extinguishers due to their effectiveness and ease of use in such scenarios.
