70% to pass

You are on a multiple-product chemical tanker. The loading plan includes cargoes of diethylenetriamine and formamide. Which statement concerning the stowage of these cargoes is TRUE?

A They must be separated by a void space or empty tank.

B The cargoes must have individual venting systems.

C The minimum segregation required is a single bulkhead.

D The valves in common piping systems must be chained closed and locked.

AI Explanation

The correct answer is C) The minimum segregation required is a single bulkhead. The reasoning for this is that diethylenetriamine and formamide are considered incompatible cargoes under the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code). The IBC Code requires a minimum of a single bulkhead segregation between incompatible cargoes to prevent the mixing of these products in the event of a tank or piping failure. The other options are incorrect because: A) a void space or empty tank is not required, B) individual venting systems are not necessary, and D) chaining and locking of valves in common piping systems is not a requirement for this cargo combination.
