Question 2598 Deck General

The correct answer is D) have containment capacity for at least one half barrel. The reason this is the correct answer is that under the regulations for fuel oil systems on vessels constructed after June 30, 1974, the fuel oil tank vents must have a means of containment capable of holding at least one-half barrel of oil in case of spill or overflow. This requirement is intended to prevent oil from being discharged into the water during the fuel loading process. The other answer choices are incorrect because they do not address the specific regulatory requirement for containment capacity around the fuel oil tank vents. Checking that the vents are not obstructed (A), having a fire extinguisher nearby (B), and ensuring the vents are opened with flame screens replaced (C) are all important safety measures, but they do not fulfill the regulatory need for containment capacity.
