70% to pass

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

A The minimum protective clothing required for taking samples of phosphoric acid is goggles or a face shield.
B Aluminum, copper, and zinc are prohibited in all valve parts in contact with these cargoes.
C Each of the cargoes must be segregated from the other by at least two barriers.
D The required warning sign must have the legend "cancer hazard" added to it.
AI Explanation

The correct answer is C) Each of the cargoes must be segregated from the other by at least two barriers. This is correct because the International Maritime Dangerous Goods (IMDG) Code requires multiple-product tankships carrying incompatible cargoes, such as crotonaldehyde, phosphoric acid, and morpholine, to have at least two barriers of segregation between the different cargo tanks. This is to prevent the accidental mixing of these hazardous materials, which could lead to dangerous chemical reactions. The other answer choices are incorrect. A) is incorrect because the minimum protective clothing for phosphoric acid may require more than just goggles or a face shield. B) is incorrect because the compatibility of valve materials depends on the specific cargo and its properties. D) is incorrect because the "cancer hazard" warning is not a standard requirement for these cargoes.
