Cargo tanks carrying grades D or E liquids on tank barges are required to be vented with which of the following?
AI Explanation
The correct answer is B) gooseneck vents and flame screens.
Cargo tanks carrying grades D or E liquids on tank barges are required to be vented with gooseneck vents and flame screens. This is in accordance with the regulations for tank barges in 46 CFR 39.20-9, which specify that cargo tanks carrying grades D or E liquids must be fitted with gooseneck vents and flame screens to prevent the passage of flame.
The other options are incorrect because: A) branch vent lines and a vent header are not specifically required for grade D or E liquids, C) forced draft blowers are not required for venting, and D) pressure-vacuum relief valves are not the primary venting method for these types of cargo tanks.
