What form of venting of cargo tanks is allowed for a tank barge certificated to carry grade B petroleum products?
AI Explanation
The correct answer is B) Individual pressure-vacuum relief valves with flame screens.
This is the correct answer because the regulations for tank barges carrying grade B petroleum products (such as gasoline) require the use of individual pressure-vacuum relief valves with flame screens for cargo tank venting. This type of venting system helps to safely regulate the pressure and vacuum in the cargo tanks while preventing the escape of flammable vapors and the entry of external flames.
The other options are incorrect because gooseneck vents (A and D) and straight vents (C) are not permitted for this type of application, as they do not provide the necessary pressure-vacuum regulation and flame prevention required for the safe carriage of grade B petroleum products.
