If your company works with materials that generate silica dust, you should actually be concerned on several different levels. The first of these is the potential for health problems that can be caused by silica dust, which can lead to a disease called silicosis.
Dust is a byproduct of almost every precast concrete operation. It is made up of very small particles suspended in the air, usually created by material movement; grinding, cutting and drilling concrete; mold cleaning; and many other processes common to our industry.
