Question 691 Deck General
70% to passYou have orders to load cargoes of carbon disulfide, diisopropylamine and pyridine on your multi-product tankship. Which statement is TRUE?
A
Carbon disulfide may be carried in NOS. 1 and 2 center tanks and diisopropylamine in NOS. 1 and 2 wing tanks.
B
A tank of carbon disulfide may be used to separate a tank of pyridine from a tank of diisopropylamine.
C
Diisopropylamine must be separated from carbon disulfide by two barriers (cofferdams, voids, empty tanks, etc.)
D
Pyridine and diisopropylamine may be carried in tanks having a common header vent.
AI Explanation
The correct answer is C: Diisopropylamine must be separated from carbon disulfide by two barriers (cofferdams, voids, empty tanks, etc.). This is because carbon disulfide and diisopropylamine are incompatible cargoes that require a minimum of two barriers to be separated from each other, as per the regulations for the safe carriage of hazardous materials on board ships. The other options are incorrect because they do not properly address the separation requirements for these incompatible cargoes.
