What type of fire extinguisher is best for electrical fires?

The best choice for extinguishing electrical fires is a CO2 (carbon dioxide) extinguisher. Carbon dioxide is effective because it displaces oxygen in the area of the fire without leaving any residue, which is particularly important when dealing with electrical equipment. Water and foam extinguishers can conduct electricity and create a risk of electrocution, making them unsafe for use on electrical fires. A dust extinguisher, while it may be effective for certain types of fires, is not typically used or recommended for electrical fires specifically. Therefore, a CO2 extinguisher is the safest and most effective option for this situation, as it can safely extinguish flames without endangering the user or damaging sensitive electrical components.
