* i <- To; Phil Rupright cc; Les Sackett From: Dick GruerLbaum* Dictated but not read Subject: Asbestos Sampling Dote: November 14, 1977 On July 22, 1977 a sampler was used on Chuck Hinderer while he was mowing grass with a reel type mower around the Trionized Plant. The sampler was run for 169 minutes and resulted in fibers concentration of .028 fibers/cc of air. This, of course, compares to the present OSHA Standard of 2.0 fibers/cc. It should also be pointed out that some laboratories consider the accuracy of this low concentration to be plus or minus 100 percent. 3 5. i One additional sample was obtained, however, was not sent to the laboratory for analysis because the sampler stopped during the sampling period thus making the information invalid.
