Question 11Safety & Environmental - QMED70% to pass
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 a dry chemical extinguisher. Dry chemical extinguishers are effective against class C fires because they interrupt the chemical reaction that fuels the fire, and they do not conduct electricity, making them safe to use on energized electrical equipment.
The other answer choices are incorrect because chemical foam, chemically treated sawdust, and mechanical foam are not recommended for class C fires. These extinguishing agents could potentially conduct electricity and would not effectively suppress an electrical fire.
