Abstract : At the request of the US Navy, the Bureau of Mines has investigated the explosibility hazards of plastic abrasive media used for removing paint from the surfaces of aircraft and aircraft sections. The tests included both original and recycled media. Four types of plastic media were tested and compared with Pittsburgh bituminous coal and polyethylene. The tests were performed in a 20-L explosibility test chamber and a 1.2-L ignitability furnace. The original coarse media used for abrasive blasting of aircraft components could not be ignited when dispersed as a dust cloud, but the fines generated during the blasting process were capable of generating strong explosions.
