Three conditions must be present for dust explosions to occur:
- A sufficient concentration of dust particles small enough to be held in suspension.
- Enough air to support combustion of the dust.
- An energy source strong enough to initiate combustion.
Proper engineering controls can mitigate the potential risks of an explosion.
Removal or control of any one of these three conditions will prevent an explosion.
Cyclones, screening devices and ventilation equipment are used to control dust levels within a dry blast system.
Proper grounding of all equipment and the use of de-ionizers and magnetic separators minimize static buildup within a dry blast system.
It takes considerably more energy to cause an explosion in eStrip® Type VII Starch-g- acrylic media than in many common, everyday materials.
eStrip GPX Type VII poses no more risk than various plastic media.
eStrip GPX media particles greater than 120 mesh in size do not ignite. Only the fine dust particles are of concern.
eStrip GPX media dust is very difficult to ignite.
