The dangers involved with handling explosives and other incendiary devices are well known. Injuries can include, but are not limited to overpressure, fragmentation, impact, and heat injury. To investigate blast injury phenomenon, a series of 30 tests was conducted on an instrumented anthropomorphic test dummy with and without protective clothing. Head and chest acceleration measurements were obtained for twenty-three of these trials. The results indicate that rapid head and chest movement following the blast wave can cause significant accelerations. These accelerations can be even more pronounced in the event of impact into a solid surface. Reduction of these potentially injurious accelerations can be realized through the use of proper protective equipment.
