Which extinguishing agent is the best for use on electrical fires?

A Dry chemical
B Foam
C CO2
D Water fog
AI Explanation

The correct answer is C) CO2. CO2 is the best extinguishing agent for electrical fires because it is a non-conductive gas that effectively smothers the fire by displacing oxygen, without causing damage to the electrical equipment. Dry chemical agents can leave a residue that can conduct electricity, while water and foam are conductive and can lead to electrocution hazards. The non-conductive properties of CO2 make it the safest and most effective choice for extinguishing electrical fires.
