Question 348 Deck General

70% to pass

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

A Butyric acid is incompatible with octyl alcohol but not propylene oxide.
B Octyl alcohol is incompatible with both butyric acid and propylene oxide.
C Propylene oxide may not be stowed in a tank adjacent to butyric acid.
D All of these cargoes are compatible.
AI Explanation

The correct answer is C) Propylene oxide may not be stowed in a tank adjacent to butyric acid. This is correct because propylene oxide and butyric acid are incompatible cargoes that should not be stowed in adjacent tanks. Propylene oxide is a highly reactive and flammable chemical, while butyric acid is a corrosive substance. Storing these two chemicals in adjacent tanks could lead to a dangerous reaction. The regulations on the stowage and segregation of incompatible cargoes on chemical tankers require that they be kept separate to prevent such hazardous interactions. The other options are incorrect because: A) Butyric acid is incompatible with both octyl alcohol and propylene oxide; B) Octyl alcohol is not necessarily incompatible with both the other cargoes; and D) All of these cargoes are not compatible and require segregation.
