Question 2706 Deck General

The correct answer is B) 3 B-II fire extinguishers must be in the machinery space of a 175-foot long fishing vessel propelled by engines with 2500 brake horsepower. This is determined by the regulations in 46 CFR 28.160, which require a minimum of 3 B-II fire extinguishers in the machinery space of a commercial fishing vessel over 65 feet in length that is propelled by engines with over 500 brake horsepower. Since the vessel in the question is 175 feet long and has 2500 brake horsepower engines, it falls under this regulation, requiring 3 B-II fire extinguishers. The other answer choices are incorrect because 2 extinguishers (A) would be insufficient, 4 extinguishers (C) would exceed the minimum requirement, and 5 extinguishers (D) would also be more than the regulatory minimum.
