What type of fire extinguisher is most suitable for electric fires?

The most suitable type of fire extinguisher for electric fires is a CO2 extinguisher. Carbon dioxide extinguishers are effective because they do not conduct electricity, making them safe to use on electrical fires. When CO2 is discharged, it displaces the oxygen around the fire, effectively suffocating it without leaving any residue, which is especially important in environments with sensitive electrical equipment.

Other types of extinguishers, such as water extinguishers, can be dangerous when used on electrical fires because water conducts electricity, creating the risk of electrocution. Foam extinguishers are primarily designed for flammable liquid fires and would also pose a risk if used near electrical sources. Wet chemical extinguishers are specifically designed for cooking oil and fat fires, not electrical fires, and are not appropriate for tackling electrical hazards. Therefore, the CO2 extinguisher is the safest and most effective choice for combatting fires involving electrical equipment.
