P h il R u p rig h t cc; Lee Sackett Subject: Asbestos Sampling From: D ick Gruenbaum- Dictated but not read i Dotei 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 Trionizad Plant. The u sampler was run for 169 minutes and resulted in fibers concentration of .028 fibers/cc of air. This, of course, compares to the present u 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. One additional sample was obtained, however, was not sent to the II laboratory for analysis because the sampler stopped during the sampling period thus making the information invalid. DOJ WRG 03026
