Reducing Silica Exposures In Stone Crushing

reduce worker exposure to respirable silica dust. Baseline dust surveys were conducted in underground limestone mines in Pennsylvania to investigate primary silica dust sources, generation levels, and controls being used. Three primary sources currently under investigation include dust generated by crushing facilities, face shots, and haul trucks.
