Semi-portable extinguishers used on inspected vessels are sizes _______________.
AI Explanation
The correct answer is B) III, IV, and V.
The regulations for fire extinguishers on inspected vessels specify that semi-portable extinguishers, which are larger and more permanent than handheld extinguishers, must be sizes III, IV, or V. These larger extinguishers provide more firefighting capability than the smaller size I and II extinguishers, which are typically found on uninspected vessels. The other answer choices are incorrect because they either omit some of the permitted semi-portable sizes (A and D) or include only the smaller handheld extinguisher sizes (C).
