U.S. Chemical Hazard and Safety Board. November 2006.
This important study from the looks at dust explosions, which are a danger in any industry that creates a fine, dusty byproduct (candy, cotton, grain, coal, various metals).
“Investigation Report: Combustible Dust Hazard Study” explores how these dusts cause variations on the same hazard: explosions if they are exposed to an ignition source. We know enough about dust dangers to issue a regulation that would include all of these workplaces, rather than doing it piecemeal (only grain and coal are covered currently).
