Question 838 Deck Safety

The correct answer is D) All of the above. Dry chemical fire extinguishers are effective on Class A (ordinary combustibles like wood, paper, cloth), Class B (flammable liquids and gases), and Class C (energized electrical equipment) fires. This makes them versatile and effective on a wide range of fire types, including burning oil, paint, and electrical fires. The dry chemical agent interrupts the chemical reaction of the fire, making dry chemical extinguishers suitable for these different fire classifications. The other answer choices (A, B, C) are incorrect because dry chemical extinguishers are effective on all those fire types, not just one.
