Flour mills have been destroyed when a flour-air mixture ignited explosively. While flour is difficult to burn on its own, when it is turned into a dust cloud in the presence of a flame it will combust rapidly due to the large reactive surface area that is exposed. Similar reactions can occur with a number of other fine combustible powders. e.g. sawdust, coal dust, grain dust (in grain elevators) and some metal powders.
