CLAYTON & ASSOCIATES -- JUNE 4 AND JUNE 5 CHEMICALS^ * -RSSABCHa---- JUN6 137<?3} I attended about 50 percent of the subject seminar to extract information useful to Chemicals in our effort to solve our VCM health problem. The seminar was,of no value. Most information presented is common knowledge to us. In fact, a number of errors were made. Conoco could easily prepare a seminar to teach this environmental consulting firm about the VCM problem. Clayton and Associates plan other seminars this summer at various locations in the United States. I strongly recommend that Conoco not be represented at these seminars. A partially completed notebook was given as a handout. I will route sections to people whose initials are shown on the attached list of notebook contents. I will also supply a copy of any other section to interested Conoco people on request. The original notes will be placed in the files of the Engineering Research Section unless directed otherwise. Clayton and Associates provide environmental sampling, survey and analytical service, including activated charcoal dosimeter tubes. (R. E. Laramy is familiar with their services.) Conocofs resin customers could be referred to these people for dosimeter analyses. The charcoal tubes and analyses cost about $12 each. Some interesting results are claimed by this firm with regard to their charcoal techniques. They claim VCM loadings up to about 58 percent, very rapid breakthrough, and ..ability to detect exposures at 5 ppb. These results differ with ours significantly. I question their accuracy, but don't feel that it is worth pursuing. If their numbers are correct, it merely demonstrates again the great variations in effectiveness between charcoals. Details are included in the writeup in Section VI.
