Industrial Hygiene Survey [Asbestos] Winchester, VA --- ABEX~CORPORATION - ' > INDUSTRIAL HYGIENE SURVEY (ASBESTOS) AMERICAN BRAKEBLOK WINCHESTER . VIRGINIA AUGUST 14 - 18. 1972 PURPOSE This survey was the continuation of a study which was initiated to determine the extent of -asbestos exposure to employees in. . the Plant. Additionalsurveys will be scheduled to complete the evaluation; ; , ` - - -'* * Several of the asbss samples collected from locations pro cessing lead compounds were also selected for lead analysis < to determine airborne concentrations at various operations. .(. ASX. Samples were collected iii five'different departments through- . out the Plant# including Book Preform# Book Press# Block Preform# Strip Finishing, and 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. Referring to Sample No. 15 in. the Analyses of Air Samples 1 or Asbestos, the concentration found at Machine No. P-11# operated by c. Orndorff was 6.01 fibers/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. Sample No. 56j 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 SPNY 003351 J : r ' - * ,,Li `j. # ________ , B I M W i , , , , - r w --------- ' t o B i i n q i O C K e r s -- -- 3" ---- " 7nT all reoularly employed personnel who Z l t S a T l ^ d p U c e of employment where airborne concen trations 5 flberff/m3u......... pwpPTRATOBY ^Q^ECTIOa.
