Measure Insulator's exposure to airborne asbestos fibers while removing asbestos containing insulation in several areas of the plant. 4-11-83, 4-13-83, 4-26-83. 6-6-83 The maximum airborne asbestos concentration measured 6.36 fibers/cc during a monitoring period of 11 minutes, while the craftsman removed insulation from piping in Intermediates. Other monitoring results covered a range of 0.17 to 2.84 fibers/cc for monitoring periods of up to 45 minutes. These concentrations are less than the permissible Ceiling of 10 fibers/cc and the permissible 8 hour TWA of 2 fibers/cc. In all cases the craftsmen were protected from exposure by use of Comfo 2 respirator with type H filter, coveralls, goggles, gloves, and boots. Share this information with Maintenance insulators. In all-areas where asbestos insulation was being removed the area was roped off and asbestos hazard signs were in place. In addition the Insulation was wetted before starting and during removal as needed. All insulation was placed in labeled plastic 6&gs for disposal. The area was washed down on completion of the job with all wet debris being scooped up for disposal, as mentioned above. Microscopy H. G. Kuntz/K. E.Williams D. L. Beagle^M. W. Bosserman, R. E.
