Which advantage does dry chemical have over carbon dioxide (CO2
AI Explanation
The correct answer is A.
Dry chemical fire extinguishers have the advantage over carbon dioxide (CO2) extinguishers in that they can be used on Class B (flammable liquids) and Class C (energized electrical equipment) fires, whereas CO2 extinguishers are less effective on these types of fires. Dry chemical extinguishers contain a powdery agent that smothers the fire, while CO2 extinguishers rely on the displacement of oxygen, which is less effective on liquid and electrical fires. This makes dry chemical extinguishers a more versatile choice for many marine applications.
The other answer choices (B, C, and D) do not accurately describe the relative advantages of dry chemical versus CO2 fire extinguishers.
