Monsanto Monsanto Company 600 N. Lindbargh Boulevard St. Louis, Missouri 63166 Phono: (314) 694-1000 July 1, 1976 DEPARTMENT OF MEDICINE & ENVIRONMENTAL HEALTH Ms. Deborah'Smith Office of Administration Personnel Division General Services Administration Room 1904 Washington* D. C. 20405 Dear Ms. Smith: Mr. Warren Easley of our Washington office has asked us to pro vide you with some information on the toxicity f*3 of PCB's. I have attached a toxicity summary of^roclor 101o^ used extensively as a capacitor dielectric fluid. This material has the lowest chlorine content of the currently available Aro- clors. It does, however, demonstrate the toxicity and handling hazards associated with all such PCB materials. As you know, we have been manufacturing these materials since 1929, and at no time have we ever had any problems with our own workers or any customers' workers handling PCB materials in the capacitor or transformer uses. We have never seen any cases of chloracne in our workers or customers' workers. This is a common statement one hears in connection with PCB handling that we have found not to be true in practice. In fact, other than its eco logical effect and its resistance to biodegradation, PCB mate rials have never posed any demonstrable problem. x I would suggest that you acquire from the American National Stan dards Institute, 1430 Broadway, New York 10018, a copy of the ANSI C 107.1-1974 entitled "Guidelines for Handling and Disposal of Capacitor and Transformer Grade Askarels Containing Polychlorinated Biphenyls". _ This document covers the only current use for which PCB's are sold by Monsanto. If you need any further information, we would be more than happy to supply it. DSW 552886 Sincerely, Jack T. it Manager Industrial Hygiene mlw STLCOPCB4091303
