Koch On April 2, 1980, a teat was set up in the Maintenance Shop demonstrating the removal of asbestos-containing gaskets (Garlock gaskets) from three flanges. These were to be removed by means of a pneumatic powered wire brush. This operation is not done frequently, but it was desired to deter mine the exposure to personnel that perform the job. The operation was monitored by J. P. Koch obtaining two area samples and a breathing zone sample of the pipefitter doing the grinding, V. J. Vanshura (Check #194). These samples were then analyzed by J. J. Stanko of the Corporation's Environmental Health Staff. The test took eight minutes to grind off the three flanges which was the duration of the air sampling. J. J. Stanko then reported that he was unable to find any asbestos-form material on the samples, indicating that there wes no exposure to asbestos during this operation. J. USEIQ00050
