Site 2 - Dump: When compared to the crusher and belt, this st. ation has lower respirable and silica concentrations. This suggests that the 37.1 kw (50 hp) fan is preventing dust rollback from the crusher as the trucks dump. Site 3 - Crusher: This location had the highest concentrations of both respirable and silica dust.
