Question 1 of 27070

You are on a multiple-product chemical tanker and will carry cargoes of butyric acid, propylene oxide, and octyl alcohol. Which statement is true?

🔍 Key Concepts

• Cargo compatibility tables in 46 CFR for chemical tankers • Specific reactivity and adjacent tank requirements for propylene oxide • Ideas of "incompatible" vs. "may not be stowed adjacent" and how they are shown in the tables

💭 Think About

• Look up each pair of cargoes (butyric acid/propylene oxide, butyric acid/octyl alcohol, octyl alcohol/propylene oxide) in the compatibility table rather than guessing from general chemistry knowledge. • Ask yourself: does the regulation distinguish between full incompatibility and restrictions on adjacency for any of these pairs? • Check whether any one pair has a stricter restriction than the others, and see which option’s wording matches that exact restriction.

✅ Before You Answer

• Verify in the 46 CFR chemical cargo compatibility table how butyric acid and propylene oxide are marked relative to each other, especially for adjacent stowage. • Confirm whether octyl alcohol has any noted incompatibilities with either of the other two cargoes or if it is generally compatible. • Make sure you understand the difference between "incompatible" (cannot be carried together as specified) and "may not be stowed in a tank adjacent to" (adjacency restriction).

Question 1 of 27070

You are on a multiple-product chemical tanker and will carry cargoes of butyric acid, propylene oxide, and octyl alcohol. Which statement is true?

Butyric acid is incompatible with octyl alcohol but not propylene oxide.

Propylene oxide may not be stowed in a tank adjacent to butyric acid.

Octyl alcohol is incompatible with both butyric acid and propylene oxide.

All of these cargoes are compatible.
