Question 1189 Deck General

The correct answer is B) Two. According to the regulations, an unmanned, cargo pump-equipped tank barge engaged in transferring grade B flammable liquids requires two B-II hand portable fire extinguishers in the cargo tank area. This is based on the requirements outlined in 46 CFR 27.100, which specifies the fire extinguishing equipment needed for tank vessels. The other options are incorrect because A) Three extinguishers would exceed the regulatory requirement, C) One extinguisher would be insufficient, and D) No extinguishers would not meet the regulatory requirement for this type of vessel and cargo.
