Frangoa Gentlemen: Early In March the "New York Times" and the "Herald Tribune", reporting the eatabllshaent of a new environmental health laboratory at Mt. Sinai Hoapital (New York City), revived aooa publicity (copy attached) in regard to Aabeatoa dust as a health hazard. We understand that a few newspapers in other cities picked it up. "Out of context" reporting leads to erroneous conclusions, and this Is no exception. Nevertheless, we should reckon that such a conaentary will recur, and all of us should use the tool we now have at our disposal to make certain our customers are acquainted with the facta: 1. You have copies of Dr. Demehl's "Asbestos Toxicology Report." Additional copies are enclosed. Use these, and call particular attention to Dr. Demehl's statements In regard to "Threshold Limit Value"fJr asbestos. Control of asbestos dust exposure is necessary, as is control of exposure to any of a variety of dusty operations. 2. Union Carbide pellets offer a clear-cut means of handling asbestos under exceptionally low dust conditions. 3. No work yet conducted or published presents, nor pro fesses to present, incontrovertible proof of a relationship between cancer and asbestos. Some publications have re ferred to the association of deleterious organic compounds, among them Jute oils from jute sacking material, and 3,4 benzo(a) pyrene. We do not use jute bags. Further, we are UCC 023545 -2analyzing random samples of oar produce, and expace shortly Co prove Che absence of any polycyclic aromatics. Tour pelleted asbestos affords customers the best means of avoiding duse hazards. Make this clear. Very truly yours, A.E.Pufahl/dh Enclosures UCC 023546
