Post O 'fice box 1246 Granite City, Illinois G2040 Dear Don: Rc: Asbestos Levels during T- nsite Cutting at DU2 In order to contain asbestos fibers that are generated during the cutting of transite, Edwards constructed a shed on the northeast corner of the DU-2 area. On October 4, 1984, four sheets of 4' x 8' x 1/4" corrugated transite were cut into three sections. This operation took approximately thirty minuses. The two employees wore protective clothing and MSA ComfoII respirators * Lth HEPA filters. To evaluate the fiber release during this c;:eration, a personal and an area sam ple were taken. The results of the personal air sample is estimate-', to be 1.43 fibers per cubic centimeter (f/cc) . This value is only an estimate since most of the particulate matter that was collected fell off the filter in transit to the laboratory. The area sample that was taken outside of the shed was 0.29 f/cc. This rela tively high level was verified by the visible dust cloud cornin'- from the shed as the coor was opened and closed. because of the observed loading of the personal samule filter ard the visible dust coming from the shed, work was stopped. To correct the dust problem associated with the cuttir ; of transite, an order for a turbine saw was placed on October 4, 1334. This saw wi ) aJl.-.v the tran site to be cut wet and reo.ice fiber release to acceptable levels. Certiljcd Industrial Hygienist cc: V. J. Grierle Shell Oil Company LAM 019555 aBS-000366
