Impact of background sources on dust exposure of bag machine operator.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, IC 9089, 1986 Jan; :1-10
The Bureau of Mines has recorded a number of different background dust sources that significantly contaminate the air breathed by bag machine operators. These background sources, observed at five different plants over the past 2 years, can expose bag machine operators to more significant dust concentrations than the filling process itself. To keep bag operator exposure within acceptable dust levels established by the Mine Safety and Health Administration, U.S. Department of Labor, the significance of these background sources must be realized, and the sources must be identified and controlled. The purpose of this work is to identify common background dust sources and show the significant effects that they have on the bag operator's overall dust exposure.
