DATE: ..DUSTRIAL HYGIENE MONITORING June 28, 1984 1 PROJECT: Monitor respiratory exposure to asbestos fibers experienced by insulators, Maintenance Department. DATE OF SAPPLES: May 9, 1984. SUMMARY: Two insulators were monitored as they removed asbestos-containing insulation on the second level of the Steam Plant, between boilers 1 and 2. One insulator was exposed to less than .11 fibers per cubic centimeter of air over a period of 1.68 hours while the second insulator was exposed to 0.13 fibers per cc over a period of 1.67 hours. Both of these exposures are below the permissible limit of 2 fibers/cc averaged over 8 hours. Both operators wore full protective clothing, including air-supplied respirators. RECOMMENDATIONS: Share this information with Maintenance insulators. METHOD OF ANALYSIS: Microscopy DATA AND REPORT BY: H. G. Kuntz/M. W. Bosserman ANALYSIS BY: IHI - Kemron COPY TO: J. E. Boley, F.

His exposure was 0.13 fibers per cubic centimeter of air over a 1.67-hour period. His job consisted of removing old asbestos-containing insulation on the second level of the Steam Plant, between boilers 1 and 2. This concentration is less than the permissible exposure limit of 2 fibers per cc of air. He wore full protective clothing plus an air-supplied, full facepiece respirator. MVB/le 2782A cc: D.

ANALYSIS BY DATA AND REPORT BYt INDUSTRIAL HYGIENE MONITORING June 22# 1984* Monitor respiratory exposure to asbestos fibers experienced by onsite contractor personnel employed by C. Brown* May 23, 1984. Two employees, : j were monitored as they removed debris from the old insulators' trailers. The operation lasted for a period of 34 minutes, during which their exposure was less than 0.33 fibers per cubic centimeters of air. The maximum permissible exposure is 2 fibers per co averaged over 8 hours. The employees wore full protective clothing and the Type H dust respirators recommended for asbestos removal. Share this information with the two employees who worked in the trailer. Air Filtration Kemron Environmental Services M. Wayne Bosserman COPY TOi J. E. Heilman, C. A. McNeill, W. V. Summers, G. W.
