PPG - Winchester Subjectt comparative Asbestos Levels The attached table lists the asbestos levels at the majority of work locations where concentrations above 5 fibers/ml have been found during one or more surveys since August, 1972. Locations where levels have been consistently low (below 5 fibers/ml) are not listed in the table. Exposures on the third shift are apparently well below the T.L.V. at all locations, and no data covering the January 31-February 2, 1973 survey date is included. If you have any questions regarding the attached information, please let me know. toDGrej Att. CC: D. K. Rennie Environmental control ABEX-153 SPNY 007149 SCF-ABEX-1670
