Description of Driving Event:

A hydrazine cylinder containing 11 liters of Hydrazine was shipped to the Kennedy Space Center (KSC). The shipping paperwork indicated the cylinder contained 1 liter of Hydrazine. The cylinder was transported by cargo air. Although transportation regulations allow cargo air transportation for quantities of this commodity up to 2.5 liters, the cylinder is covered by a Department of Transportation (DOT) exemption that specifically requires either motor vehicle or cargo vessel (boat) transportation regardless of quantity. The exemption takes precedence over the general regulation.
