70% to pass

Semi-portable extinguishers used on inspected vessels are sizes _______________.

A IV and V
B III, IV, and V
C I, II, and III
D II, III, and IV
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.
