AR226-2001 To: R.D. Lanyon J.F. Kline W.A. Ott J.C. Beckner D.N. Washburn From: D.J. Ruffin ces S.J. Watson Dr. Y.L. Power J.E. Crum C.A. Dykes W.C. Morris D. D. Williams Oct. 10, 1985 C-8 TEST RESULTS C-8 test results on both area and personal samples in the fine powder area are much higher in 1985 than previous years. The Industrial Hygiene Report for October 1984- October 1985 indicated that 10 area samples were above 100 of the established A.E.L. for C-8 in the most recent analysis. In addition, two personal samples during the past year have had results exceeding the established A.E.L. ' Some of the area samples have increased greatly over the past four years. For example, the Fine Powder dryer control room has had results of 2.997 and 4.35 mpb C-8 in 1985 (535 and 776 % of the A.E.L. , respectively). However, in 1982 and 1983 it was rare for this sample location to reach even 30 % of the A.E.L. To discuss this upward trend in the C-8 test results and to decide what action is needed in the area, I would appreciate your participation in a meeting on Thursday, Oct. 24, at 10:08-11:00 am, in the B--168 small conference room. Please let me know as soon as possible if you can not attend. Thanks Some of you have already looked at the rise in C-8 results, and any of your information that you could share with the group would be appreciated. Some of the questions that I would like to discuss at the meet!ng are: . Have C 8 test results on blood samples shown a similar increase in level for operators working in the Fine Powder area? . Do the area samples indicate a significant increase in the C-8 level"? Are the results valid? What changes in the area have occurred over the past two years which could explain a rise in the C-8 levels? What actions should be taken by area supervision to reduce C-8 levels? Do the current C-8 test results (both air and blood samples) indicate that a health hazard may exist? EID079666 AJP002296
