What Makes Combustible Dust an Explosion Hazard?
Combustible dusts become an explosion hazard when they are suspended in the air in the proper concentration in a confined or semi-confined vessel, area, or buildingMark. With the oxygen present in the air, all that is needed is an ignition source for an explosion to occur. Many variables can affect the explosibility of a dust. To fully assess the risk of a dust explosion, it may be necessary to have the materials involved tested by a specialized lab.
