HIVAC is a division of The Maintenance Men, Inc that specializes in removing dust from overhead areas. We do not blow down or knock down dust. In fact, our process can be performed while most of our customers continue to produce.
Particulate debris produced by the manufacturing process can be harmful to people & equipment. This dust can accumulate on any flat surface in the area such as ceiling truses, rafters, ducts, lighting, tops of equipment, etc. This dust, under the right circumstances, can become ignited causing an explosion.
Below is a video from CBS's 60 Minutes on the dangers of Combustible Dust. Also a few links that provide information on what OSHA says about the growing problem of Combustible Dust in the nations manufacturing industries.
