Pyridine and diisopropylamine may be carried in tanks having a common header vent.

A tank of carbon disulfide may be used to separate a tank of pyridine from a tank of diisopropylamine.

Carbon disulfide may be carried in NOS. 1 and 2 center tanks and diisopropylamine in NOS. 1 and 2 wing tanks.

Diisopropylamine must be separated from carbon disulfide by two barriers (cofferdams, voids, empty tanks, etc.)
