Which extinguishing agent is the best for use on electrical fires?
AI Explanation
The correct answer is B) 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 any damage to the electrical equipment. Water, foam, and dry chemical agents can all conduct electricity, posing a risk of shock hazard when used on live electrical fires. CO2 extinguishers are specifically recommended for Class C (electrical) fires in the US Coast Guard regulations.
