Question 1211 Deck General

The correct answer is B) One B-II fire extinguisher. According to the Code of Federal Regulations (CFR) for the US Coast Guard, an unmanned oil barge with no cargo pumps aboard is required to have at least one B-II fire extinguisher on board during transfer operations. This is specified in 46 CFR 35.10-5, which outlines the fire extinguishing equipment requirements for tank vessels. Since the barge has no cargo pumps, it does not require the additional A-II or B-II extinguishers that would be needed if it had pumps. The other answer choices are incorrect because they do not align with the specific requirements for an unmanned oil barge with no cargo pumps. Options A, C, and D call for the wrong types or quantities of fire extinguishers for this scenario.
