Carbon dioxide (CO2) extinguishers are particularly effective for electrical fires due to their unique properties. This type of extinguisher works by displacing oxygen in the surrounding area, which is essential for combustion. When CO2 is released, it creates an inert atmosphere that suffocates the fire. Additionally, CO2 does not leave any residue after use, making it ideal for situations involving electrical equipment, where residue could cause further damage or create safety hazards.

When dealing with electrical fires, it is crucial to use an agent that does not conduct electricity. CO2 extinguishers are non-conductive and are thus safe to use on energized electrical equipment. In contrast, using water or foam extinguishers on electrical fires can pose significant risks since water is a conductor of electricity and could lead to electrocution. Dry chemical extinguishers are also helpful for electrical fires but may leave a residue that could interfere with delicate electrical gear or systems.
