Quartz Plant How To Control Dust

The intent of this dust standard reduction is to restrict miners’ exposure to respirable quartz to a time-weighted average concentration of 100 microg/m3. The effectiveness of this indirect approach to control quartz exposure was evaluated by analyzing respirable dust samples collected by MSHA inspectors from 1995 through 2008.
