You are carrying cargoes of crotonaldehyde, phosphoric acid, and morpholine on your multiple-product tankship. Which of the following statements is TRUE?

Correct Answer: Option C — Each of the cargoes must be segregated from the other by at least two barriers.

Chemical compatibility rules in 46 CFR Part 153 mandate double-barrier segregation between highly reactive or hazardous categories such as crotonaldehyde, phosphoric acid, and morpholine to prevent dangerous intersystem leakage and subsequent exothermic reactions.
