Question 694 Deck General

The correct answer is B) Pyridine and diisopropylamine may not be carried in tanks having a common header vent. This is correct because these two cargoes are incompatible and should not be carried in tanks with a common vent system. Carrying incompatible cargoes in tanks with a shared vent could lead to dangerous reactions or contamination. The regulations require that incompatible cargoes be separated by having independent vent systems. The other options are incorrect. Option A would allow the cargoes to be carried in the same vent system. Option C is incorrect because diisopropylamine cannot be used to separate pyridine and carbon disulfide. Option D is incorrect because pyridine and carbon disulfide require more than two barriers of separation.
