January 26, 1972 PLAINTIFF'S exhibit \VH-1030 Mr. Robert Kurz Wes+inghouse Electric Sha rp sviI Ie Avenue Sharon, Pennsylvania Corporation Dear Mr. Kurz: At the request of George Cochrane of our Pittsburgh sales office enclosed is literature describing the use of RG-144. I have also enclosed information on RG-244, a product more similar to pyrogenic silica in performance, but less expensive than Cabosil or Aerosil. RG-244 is an excellent viscosity control agent for epoxies and would be used at a much lower level than RG-144 or silica. .......... During 1971 we shipped RG-144 to Westinghouse locations in Greenville, Pittsburgh and Sharon, Pa. and to Hampton, S.C. With regard to asbestos toxicology information, we are preparing a Corporate "position paper" on the entire subject and it should be available in 2-3 months. The new federal regulations and general publicity about asbestos hazards are directed at large consumers and those exposed for long periods of time to asbestos dust. Your relatively small usage and exposure to RG-144 should present no problems. I would suggest that production workers use a res pirator during handling and dumping of RG-144 into your resin system. No dust will be generated after the asbestos is wet out with resin. Two respirators of similar design are recommended: Willson's Model No. 1009 with R-520 filter and MSA's No. 86432 with Type "H" UItra-fiI ter. Both of these have Bureau of Mines approval for asbestos and would also serve quite well for pyrogenic silica and similar dusty materials. i-ir. rtooerT Kurz Westinghouse Electric Corp. Sharon, PA -z- January 26, 1972 By copy of this letter to Mr. Ingalls of this office, I am asking him to get in touch with you in 2-3 weeks to answer any additional questions you may have.
