Question 813 Deck General

The correct answer is A. Regulations require that cargo pump rooms on tank barges constructed in 1965 or earlier must be equipped with a fixed natural ventilation system. This is specified in 46 CFR 32.35-15, which outlines the ventilation requirements for cargo pump rooms on tank vessels. The other answer choices (B, C, and D) do not accurately reflect the regulatory requirement for tank barges constructed in 1965 or earlier, which is the focus of the question.
