ETHYL CORPORATION Inter-Office TO: FROM: F. H. Currie R. N. Matherne ADDRESS: PDC ADDRESS: BR Tower SUBJECT: Asbestos Monitoring DATE-: August 29, 1986 I collected air samples at the PDC in ten- selected areas where asbestos containing materials are known to be present. All of the samples were well below the 0.1 fiber/CC action level for asbestos. The values ranged from 0.002 to 0.01 fiber/CC of air. The-results (Table I) represent area concentrations not employee exposure. Please note the analytical method counts all fibers and not' just asbestos. If you have any questions, please call.
