The carbon dioxide extinguisher is specifically designed for electrical fires because it works by displacing oxygen, which is essential for combustion, without leaving any residue that could damage electrical equipment. Carbon dioxide is a non-conductive agent, making it safe to use on live electrical fires. It effectively interrupts the chemical reaction of the fire and cools the surrounding area without conducting electricity, which is critical for safety in environments where electrical equipment is present.

In contrast, other extinguishing agents like water can conduct electricity and pose a significant risk of electric shock or further spreading the fire when used on electrical sources. Dry chemical extinguishers can be effective, but they may leave behind a residue that can potentially damage electronic equipment or create additional hazards if not cleared properly. Foam extinguishers are typically suited for flammable liquids rather than electrical fires, as they can also create risks when in contact with live electrical components.
