Question 2596 Deck General

The correct answer is B) mechanical means of closing. The Code of Federal Regulations (CFR) requires that each scupper in an enclosed deck area have a mechanical means of closing, such as a valve or flapper, to prevent the accidental discharge of oil or other pollutants. This regulation is in place to ensure that the vessel operator has positive control over the discharge of any potential pollutants from the enclosed deck area. The other options are incorrect because they do not meet the regulatory requirement. A soft rubber plug, a two-piece soft patch, or a wooden plug would not provide the necessary mechanical control over the scupper discharge as required by the pollution prevention regulations.
