How many, and what type, fire extinguishers are required on an unmanned oil barge during transfer operations, if the barge has no cargo pumps aboard?

Correct Answer: Option B — One B-II

Per 46 CFR 34.50-10, unmanned tank barges are required to carry specific fire extinguishing equipment based on their size and cargo. For a barge without cargo pumps, a single B-II extinguisher is the minimum regulatory requirement to address potential small fires on deck during transfer operations or while in transit.
