Grittie February 26, 1986. Results of Qualitative Analysis Of Lint Vogue-Swift D. A. Boggs Attached, please find the results of the qualitative analysis for asbestos performed on the samples of lint removed from the Vogue-Swift washing machines. Please note that a small amount of asbestos was indeed found. This information leads me to recommend that we continue to provide laundering services to the insulators when they are working with asbestos. This service provides the vital function of preventing a man from possibly contaminating his family by carrying asbestos home on his clothing. In addition, laundry bags containing these clothes should continue to be labelled as asbestos contaminated so as to provide adequate warning to the employees of Vogue-Swift. If you have any questions on the results or recommendations, feel free to call me at 521.

Painters had used air to blow dirt off of the top of ventilation ductwork in preparation for painting to be done. IH took a bulk sample of material which had been blown off the ductwork. Upon analysis, it was determined that the sample contained a small amount of asbestos. According to Poly II operators, the area had been quite dusty while the painters were working. After IH had been called, the painters were told to stop the operation. 4/23/87 to 4/24/87 SAMPLE Z-9218 DATE 4-23 TYPE Area TIME START STOP 11:05 13:00 MINUTES RESULTS 115 CO. 01 f/cc COMMENTS Desk at SW wall near K-57.

McMillan To comply with the new asbestos standard, it is necessary to monitor all employees who could potentially be exposed to asbestos. An exposure potential exists for those craftsmen who remove asbestos gaskets. From the small amount of historical I.H. data that we have, exposure should be inconsequential. Our data base is, however, not large enough to statistically support this premise. Therefore I must ask that you or your craftsman notify I.H. when asbestos gaskets are being removed. Please provide as much lead time as possible so that we will have monitoring equipment available and won't cause any delay in the work. Please call either myself (ext. 521) or Chuck McMillan (ext. 475). Thank you for your cooperation.

Monitor K-40 operator for asbestos exposure due to ambient air movement. The operator performed the regular duties of the K-40 operator. 1/22/87 TIME START TIME STOP RESPIRATOR? RESULTS 8:45 15:00 No <0.003 f/cc BZ = Breathing Zone DISCUSSION: The results (<0.003 fibers/cc) are well below the OSHA permissible exposure limit of 0.133 fibers/cc TWA]^ and also well below the action level of 0.667 fibers/cc (for 12 hours). This indicates that during a normal day the K--40 operator was not overexposed to asbestos. RECOMMENDATIONS: Request I.H. monitoring of other operators who may be concerned about asbestos exposure. This will assist in pinpointing any "trouble spots". Share this information with operators. METHOD OF ANALYSIS: Microscopy DATA AND REPORT BY: C. R. McMillan/T. L.

Both the personnel and the area samples show levels well below both the action level (0.0667 fibers/cc - 12 hour average) and the OSHA Permissible Exposure Limit (TWA^2 of 0.133 f/cc). Where it is suspected that an exposure potential may exist, I.H. monitoring should be requested. Share these results with area operators. METHOD OF ANALYSIS: Microscopy DATA AND REPORT BY: T. L.

A negative pressure enclosure was built around the reactor for the purpose of deinsulation. DATE OF SAMPLES: 2/10/87 SAMPLE TYPE TIME START TIME STOP RESPIRATOR RESULTS Z-8962 Z-8963 BZ BZ 10:30 10:32 11:23 11:21 Airline Airline 0.31 fibers/cc 0.52 fibers/cc BZ = Breathing Zone DISCUSSION: RECOMMENDATIONS: METHOD OF ANLYSIS: DATA AND REPORT BY: ANALYSIS BY: COPY TO: Both samples showed air concentrations above the OSHA PEL during the monitoring period. Respiratory protection was worn during the entire monitoring period. Even if one considers 4 - one hour exposure periods with no other exposures and averages this over 8 hours, sample Z-8963 would be above the PEL TWAg of 0.2 fibers/cc. Obviously, these concentrations are unacceptable. Wet methods must be used more effectively. The use of the enclosure keeps all ambient fibers in close proximity to the worker and therefore the methods used to prevent fiber release must be even more stringent. It goes without saying that respirators must continue to be used when working in the temporary enclosure. This will not be counted as an overexposure since respiratory protection prevented the employee from actually being exposed to the material. Microscopy T. L. Grittie J.H.M. Labs D. A. Boggs, E. L.
