What type of fire extinguisher is suitable for use on electrical fires?

A dry chemical extinguisher is suitable for use on electrical fires because it contains agents that can interrupt the chemical reaction of the fire without conducting electricity. Common dry chemical agents like monoammonium phosphate, sodium bicarbonate, or potassium bicarbonate are effective in combating Class C fires, which involve electrical equipment. These extinguishers are designed to provide a rapid flame knockdown and can be used safely on energized electrical systems.

When using a dry chemical extinguisher, it's crucial to follow safety protocols, such as maintaining a safe distance from the fire and ensuring the device is rated for use on electrical fires, which is indicated by a Class C designation on the unit. This ensures that both the firefighter and the extinguishing agent remain safe from the potential hazards of an electrical fire.
