Which fire extinguisher is suitable for use on electrical fires?

Explanation:
Electrical fires require an extinguishing agent that won’t conduct electricity and won’t leave a residue that could damage live equipment. A carbon dioxide extinguisher does exactly that: it’s non-conductive and leaves no residue, so it can suppress a fire around electrical gear without risking a short or corrosion. It works by displacing the surrounding air and smothering the flames, which is effective for small, contained electrical fires. By contrast, water- or foam-based extinguishers introduce liquid that can conduct electricity and potentially shock the operator or spread the fault. Dry powder can be used on electrical fires, but the powder leaves a fine residue that can contaminate electronics and require thorough cleaning. So, for safely handling electrical equipment fires, the CO2 option is the best choice.
