Dust Explosion 粉尘爆炸
A dust explosion is a dangerous kind of industrial accident that can occur in certain production processes where ambient air is filled with industrial dust. Many kinds of dust can cause explosions, but experts say that explosions of metallic dust are more powerful than those caused by flour, sawdust, or even coal, and just about as explosive as dynamite, because metal conducts energy especially quickly. There are three conditions for a dust explosion: a concentration of dust, available oxygen, and a spark or flame. Thus the key to preventing such deadly accidents lies in proper ventilation, dust removal equipment, and use of spark-free electrical products.
