Question 2707 Deck General

The correct answer is C) 4 B-II fire extinguishers must be in the machinery space of a 175-foot long fishing vessel propelled by engines with 3300 brake horsepower. This is based on the requirements in 46 CFR 28.160, which states that for vessels with over 500 horsepower, there must be one B-II fire extinguisher for every 1000 horsepower or fraction thereof. Since this vessel has 3300 horsepower, it requires 4 B-II fire extinguishers in the machinery space. The other options are incorrect because A) 2 would be insufficient for the horsepower, B) 3 would be too few, and D) 5 would be more than required.
