Question 808 Deck Safety

The correct answer is B) Foam provides cooling as a secondary effect. Foam is an effective smothering agent that works by cutting off the oxygen supply to the fire. As a secondary effect, the water content in the foam also provides cooling to the burning materials. This cooling effect helps to further suppress the fire. The other answer choices are incorrect: A) Foam is not effective for combustible metal fires, which require specialized extinguishing agents. C) Foam does not work well on electrical fires, as the conductive properties of the foam can actually spread the electrical fire.
