Abstract: Avoidance of electrical explosive hazards from a proliferation of electrically initiated explosive devices in ordnance systems in an increasingly intense military electromagnetic environment, requires the proper determination of safe operating distances and procedures for emitter and ordnance combinations. This paper addresses threats arising in such situations. It presents some aspects of the policy, standards, philosophy, analysis and trials work performed in Australia to minimise such threats so that ordnance and weapon systems will remain safe and suitable for service. The current situation and capability in Australia are discussed, together with new and emerging techniques, which may have application in this field. Concern is expressed at the continuing lack of a suitable electromagnetic environment generation capability and the diminishing instrumentation, trials capability and experience within Australia. Recent changes to the role of the Australian Ordnance Council, and the creation of the Joint Armament Logistic Organisation have some potential to ameliorate this situation.
