To fight a class "C" fire, you should use carbon dioxide or _______________.
AI Explanation
The correct answer is A) dry chemical.
To fight a class "C" fire, which is an electrical fire, you should use carbon dioxide or dry chemical extinguishers. Carbon dioxide and dry chemical agents are effective at extinguishing electrical fires because they work by smothering the fire and interrupting the chemical reaction, without leaving behind any conductive residue that could damage electrical equipment.
The other options are incorrect because chemical foam and mechanical foam are typically used for class A (ordinary combustible) and class B (flammable liquid) fires, while chemically treated sawdust is not a standard firefighting agent.
