70% to pass

You are preparing to load fuel oil on a vessel of 150 gross tons constructed after June 30, 1974. Before loading, you must check that the fuel oil tank vents _______________.

A have a fire extinguisher within the immediate area
B are opened and the flame screen replaced
C have portable containment capacity for at least 5 gallons
D are not obstructed by on-deck cargo
AI Explanation

The correct answer is C) have portable containment capacity for at least 5 gallons. According to the regulations for fuel oil handling on vessels, before loading fuel oil, the fuel oil tank vents must have portable containment capacity of at least 5 gallons to contain any potential spills or leaks. This requirement ensures that any minor spills can be quickly contained and cleaned up, preventing environmental damage. The other options are incorrect because they do not directly address the requirement for portable containment capacity at the fuel oil tank vents. Option A is irrelevant, option B is about opening the vents and replacing the flame screen, and option D is about obstructions, which is a separate requirement.
