Question 808 Deck General
70% to passWhat is NOT required of the cargo tank venting on a tank barge carrying grade A liquids?
A
Each cargo tank must have a vent.
B
A vent header must be fitted with a pressure-vacuum valve.
C
The diameter of the vent must be greater than 4 inches in diameter.
D
The vent must extend to a reasonable height above the weather deck.
AI Explanation
The correct answer is C) The diameter of the vent must be greater than 4 inches in diameter. The reasoning behind this is that the regulations do not specify a minimum vent diameter for tank barges carrying grade A liquids. The regulations only require that each cargo tank have a vent, the vent be fitted with a pressure-vacuum valve, and the vent extend to a reasonable height above the weather deck. There is no requirement for the vent diameter to be greater than 4 inches. The other options (A, B, and D) are all correct requirements, but option C is not a regulatory requirement for this type of vessel.
