Samples were collected in five-different departments through- . out the Plant# including Book Preform# Book Press# Block Preform# Strip Finishing# end Inspection and Packaging. . - ... The results of the asbestos study disclosed two (2) locations where airborne asbestos concentrations were above the current eight-hour time weighted average exposure limit of 5 -fibers/ml. . h. Referring to Sample No. 15 in. the Analyses of Air Samples for Asbestos# the concentration found at Maahine No. P-11# operated by c. Orndorff was 6.01 fibere/ml. Exposure levels at* other Block Preform machines in the area were also elevated# but did not reach the 5 fiber/ml exposure limit* It was noted that the mix is handled intimately by the operators during the pre form cycle. In addition' to manually transferring the mix from container to the mold# the'material is measured and spread by hand. As none of the Preform units are provided with adequate exhaust ventilation# the continuous manual operations are generating increased airborne concentrations of.asbestos fibers. - * ' - ,- -......................... 5................................. Sample No. 56; at a concentration of 5.37 fibers/ml# was . collected at the vertical saw adjacent to the Book Press De partment. The saw was operated by R. F. Putnam# and was in nearly continuous use during collection of the sample. The unit is not provided with local exhaust ventilation# and sig nificant quantities of airborne particulates are'generated abex-121 SPNY 003351. SCF-ABEX-1500
