Explosive Dust
A dust fire is, in a sense, the result of a perfect storm. The powder has to form a cloud in a confined area and touch an ignition source, such as a spark, flame or overheated pipe. Accidents are unlikely, but, when they occur, the result is often catastrophic. At least 900 workers have been killed or injured in dust fires or explosions since 1980.
