250: 22: 168:, may detonate from a firm jolt and so cannot be legally transported in pure form. Acetone peroxide is often used by amateurs and terrorists as a means to detonate other explosives as well as acting as the main blasting agent, often resulting in injuries or death to those who underestimate its sensitivity. A number of methods are known to desensitize nitroglycerine so that it can be transported for 187:, can be safely handled as they will not explode from casual shocks such as being dropped or lightly knocked by a tool. However, they may explode if struck forcefully by a metal tool, and would certainly explode in the barrel if they were used in an artillery 140:. A variety of tests and indices are in use, of which one of the more common is the Rotter Impact Test with results expressed as FoI ( 291: 144:.) At least four other impact tests are in common use, while various "gap tests" are used to measure sensitivity to blast shock. 94: 66: 73: 169: 43: 113: 51: 80: 47: 62: 136:.

Reliable initiation of such materials requires the small explosion of a 249: 157: 257: 200: 192: 177: 130: 21: 173: 204: 231: 219: 195:.
