Abstract
Worker exposures to respirable free silica (7631869) were determined at five granite processing facilities in Vermont and twelve similar facilities in Georgia during 1973 and 1974. The surveys were part of a NIOSH study of silica exposures of workers in the granite industry (SIC-1423). There was an average of 13.0 percent free silica in samples collected at the Vermont granite facilities. In the five Vermont facilities, 27, 0, 42, 43, and 50 percent, respectively, of all air samples analyzed exceeded the OSHA standard for respirable free silica of 100 micrograms per cubic meter. For the 12 Georgia facilities, the percentage of air samples exceeding the OSHA standard was 7, 21, 9, 24, 29, 15, 75, 22, 17, 11, 75, and 25 percent, respectively. There was an average of 13.4 percent free silica in the total number of samples collected in Georgia. Of the granite workers in Vermont, 35.9 percent were exposed to free silica in concentrations above the OSHA standard, compared with a comparable figure of 18.3 percent for the Georgia workers. The authors recommend that exposures in two operations, wire sawing and polishing, for both Vermont and Georgia facilities be reduced.
