The presentation deals with the hazard classification of ammunition and explosives and unique military related dangerous materials. Although the discussions involve numerous government agencies, the emphasis is placed on how the matter is addressed at the US Army Armament Research and Development Center, Dover, NJ ARDC. Hazard classification is presented as a system of policies and procedures that establish the requirements, specify the items, provide the test procedures and assign responsibilities. At ARDC, the policies and procedures are applied to items of ammunition and explosives to determine their dangerous characteristics and assign those that pose similar hazards to uniform categories. The classifications are used to regulate the handling, storage and shipping to acceptable levels of risk.
