Quantity-distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...
The United States Navy formed the Weapon System Explosives Safety Review Board (WSESRB) in 1967 as a result of two deadly accidents involving explosive ordnance aboard US aircraft carriers: the 1966 USS Oriskany fire, and the 1967 USS Forrestal fire. [1] The subsequent investigation recommended an independent review process be established.
Impact testing: The impact testing of explosives is performed by dropping a fixed weight onto a prepared sample of the explosive to be tested from a given distance. The weight is released, impacts upon the sample, and the result is noted.

The remaining bomb disposal units were redesignated as "explosive ordnance disposal" in 1949. When the Korean War started in 1950, the U.S. Army faced an urgent need for an EOD capability. Unfortunately, there was a lack of personnel, training, and equipment that require a rapid correction and significant investment.
The grenade weighed 250 g (8.8 oz) and contained 160 g (5.6 oz) of explosive, its lethality radius is 3 m (9.8 ft), but due to the deliberate "fragmentation-free" design of the grenade, a distance of 4 m (13 ft) is considered safe.
The explosive trace detectors utilizing AFPs, known as Fido Explosives Detectors, were originally developed under the Defense Advanced Research Projects Agency (DARPA) Dog’s Nose program and is now produced by FLIR Systems. The current generation, provides broad-band trace explosive detection and weighs less than 3 lbs.
Some explosives incorporate powdered aluminum to increase their blast and detonation temperature, but this addition generally results in decreased performance of the shaped charge. There has been research into using the very high-performance but sensitive explosive CL-20 in shaped-charge warheads, but, at present, due to its sensitivity, this ...
