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

Correct Answer: Option A — The heating coils to the cargo tank loaded with methyl acrylate must be blanked off.

Methyl acrylate is a polymerizable product susceptible to hazardous self-reaction when exposed to elevated temperatures. Per 46 CFR and the Chemical Data Guide, heating coils in tanks containing this cargo must be securely blanked off to prevent polymerization.
