The NADCA (North American Die Casting Association) has posted a series of informative training videos on YouTube regarding combustible dust. These cover a variety of subjects from fire prevention to employee evacuation to controlling ignition sources.
One of these videos, specific to industrial dust collectors, can be viewed here: Combustible Dust Training - Section 3 - Dust Collection. Watch especially for the information starting about 1 minute into this video. The more informed you are about combustible dust when making a dust collector purchase decision, the better.
