Tests were required to determine the hazard classifications for storage and shipment of M50 Igniters. Separate classifications were required for Quantity-Distance, Storage Compatibility, and ICC Shipping. A series of 6 detonation tests were conducted to determine if the igniter would detonate within its individual shipping container and if there would be propagation from one container to another. Also an open fire test was conducted to demonstrate any detonation possibilities. Only normal type ignition occurred in all 7 tests. The igniter shipping containers burst along a soldered joint from the pressure of the blasting cap and igniter. No measurable overpressures were recorded at a 5 ft distance. The time expended for the igniters in metal shipping containers shipped 12 to a box to cook-off in an open fire test ranged from 6 to 10 minutes.
