When dust becomes airborne it settles on surfaces throughout facilities. It is believed that 1/32 of an inch (the size of a paper clip) of dust covering more than 5% of a room’s surface can cause an explosion (there are variations to this rule of thumb depending on a number of factors). In order for an explosion to happen, a “fire triangle” must occur. Dust is one element; the other elements are oxygen and an ignition source. When combined with other factors, these elements mix and can cause a “dust explosion pentagon”.

The most dramatic hazard associated with dust is secondary explosion and dust explosions. Throughout Canada and the USA these accidents are more common than many people realize. Cleanup or “plant dust down” of combustible dust, also known as explosive dust, is a required preventative maintenance program in manufacturing and production facilities.  Combustible Dust has been fueling tremendous explosions and fires throughout Canada that could be avoided. In many accidents, employers and employees were unaware that a hazard even existed.
