70% to pass

You are on a multiple product tankship and carrying methyl acrylate, diethanolamine, and triethylamine. Which statement is TRUE?

A The heating coils to the cargo tank loaded with methyl acrylate must be blanked off.
B Methyl acrylate may be loaded in a tank adjacent to diethanolamine but not triethylamine.
C Each crew member working on deck must have an emergency escape breathing apparatus.
D Valve components made of aluminum, copper, or zinc may not be in contact with the cargoes.
AI Explanation

The correct answer is A) The heating coils to the cargo tank loaded with methyl acrylate must be blanked off. This is correct because methyl acrylate is a polymerizable cargo that must be carried with all heating sources isolated to prevent unintended polymerization. The heating coils must be blanked off or otherwise isolated from the cargo tank to ensure safe transport. The other options are incorrect because: B) methyl acrylate and diethanolamine can be loaded in adjacent tanks, but triethylamine should be segregated; C) emergency escape breathing apparatus are not required for all crew members on deck; and D) certain metals like aluminum, copper, and zinc are compatible with these cargoes and can be used in valve components.
