In Part 1 of this series, the authors discussed a recent study that evaluated dust levels at two Portland cement operations to determine how measured dust levels relate to a dust standard change being proposed by the Mine Safety and Health Administration (MSHA). These two operations differed in that one used the dry- and the other the wet-processing technique. At both operations, respirable dust measurements were taken throughout the entire cement making process. In addition, measurements were taken on the perimeters of the properties to determine relative dust quantities traveling toward adjoining residential areas. Evaluations were performed at each operation during the summer and winter to compare dust levels in both weather conditions. Area samples were collected to investigate problem areas with the goal of making recommendations on ways to lower dust levels in areas with higher concentrations.
