Cargo tanks on barges fitted with goose neck vents and flame screens are limited to carrying which grade of cargo?

A A and below
B B and below
C C and below
D D and E only
AI Explanation

The correct answer is D) D and E only. Cargo tanks on barges fitted with goose neck vents and flame screens are limited to carrying Grade D and E cargoes only. This is because these types of vents and flame screens do not provide the same level of vapor control and explosion protection as pressure/vacuum relief valves required for carrying higher grade (more volatile) cargoes like Grades A, B, and C. The other options are incorrect because: A) A and below is too restrictive, as these barges can carry Grade D and E cargoes. B) B and below is also too restrictive. C) C and below would allow for more volatile cargoes than the regulations permit for this type of venting system.
