Decreasing dust levels with strategic ventilation.
Pit Quarry 1991 Jul; 84(1):48-53
The U.S. Bureau of Mines has been performing various projects in minerals processing over the past few years in an effort to lower dust exposures. These projects have been directed at source-control developments in order to lower dust exposure at a particular job function. In some cases, these dust-control developments provided a carryover effect in lowering the exposure of other workers in an area of the mill, but in no case did it ever lower the dust exposures throughout the mill building. Through a cooperative effort between the Bureau and Marblehead Lime Company, a mill ventilation system was shown to lower respirable dust concentrations throughout the entire building in a very cost-effective manner.
