Semi-portable extinguishers used on inspected vessels are sizes _______________.
AI Explanation
The correct answer is B) III, IV, and V.
According to the US Coast Guard regulations, semi-portable fire extinguishers used on inspected vessels must be sizes III, IV, or V. These larger extinguishers are considered semi-portable because they are larger and heavier than the handheld, portable extinguishers (sizes I and II). The larger sizes provide more fire-fighting capability for larger vessels.
The other options are incorrect because size I, II, and III extinguishers are considered portable, not semi-portable, and size IV and V extinguishers are the only sizes classified as semi-portable for inspected vessels.
