Which type of extinguisher is suitable for electrical fires?

The carbon dioxide extinguisher is suitable for electrical fires because it works by displacing oxygen, which is necessary for combustion. When CO2 is released, it creates a non-flammable barrier between the fuel and the oxygen in the environment, effectively suffocating the fire.

This type of extinguisher is advantageous for electrical fires as it does not conduct electricity, reducing the risk of further electrical shock or damage. It leaves no residue, making it safe to use on sensitive equipment like electrical panels, computers, and appliances, which is a crucial factor in choosing an extinguisher for electrical fires.

In contrast, water extinguishers are ineffective and dangerous for electrical fires because water conducts electricity and can create a shock hazard. Foam extinguishers, while effective on flammable liquid fires, also pose risks when used on electrical fires due to potential conductivity. Powder extinguishers can be used but might leave a harmful residue that can damage the equipment involved. Thus, carbon dioxide extinguishers are the preferred choice for safely and effectively handling electrical fires.
