Dust explosions and vacuum cleaners

The CSB has been doing a great service by increasing awareness about dust explosions. Dust explosions can occur in sugar, sawdust, coal, and in fact anything that is combustible including combustible metals. Housekeeping plays a very important part in eliminating dust in the work area. Industrial vacuum cleaners are available to do the job safely. One such cleaner is given in this youtube link. I am not endorsing their product but I thought that the video was a good one!
