Items of particular interest to us are underlined. BUSINESS MEETING The present slate of officers were: C. G. Thompson, Tenneco, Chairman M. G. Glenn, General Tire, Vice-Chairman (absent) S. J. Moll, Borden, Secretary H. E. Kling, American Chemical, Treasurer W. J. Boyle, Jr., Monsanto, Program Chairman } r The officers recommended against the V.C.S.A. associating with the S.P.E. or S.P.I. A motion was passed to keep the group an independent body. New memberships include Norsk Hydro A.S. of Norway, Promociones Industriales, S.A., of Mexico, Shell Chemical of Deer Park, Texas, and Pittsburgh Plate Glass Industries, Inc. \ Additional inquiries have been received from Farbewerke Hoeschst of West Germany and Montecatini Edison SPA of Milano, Italy. A nominating committee proposed a new slate of officers. The slate was accepted and took office following the adjournment of this meeting. M. G. Glenn, General Tire, Chairman R. A. Asti, Stauffer, Vice-Chairman J. C. Flores, Great American, Treasurer J. R. Mehall, Hooker, Secretary H. G. Smith, Ethyl Corp., Program Chairman The business meeting took only twenty minutes.

Ten companies have an AOL program already. B. F. Goodrich has long been the leader in doing extensive employe analysis to detect AOL early. Europe has recently reported many cases of AOL in PVC plant employes. Originally thought to be caused by hand reactor cleaning, cases in lead operators and other non-cleaners now proves that AOL is caused by repeated exposure to low concenxrations of VCM (50 ppnU J Bulk Truck Loading Four companies use life lines on operators while loading and climbing on bulk trucks. Several companies expressed concern at the high injury potential of this operation. d. Fisheye Control > Pantosote indicated that maintaining the oxygen level in 5 the vapor space above incoming VCM tank cars below 100 ppm would have a great effect on reducing fisheyes. Airco, Pantasote and Diamond Shamrock confirmed that once the oxygen level in the RVCM system was monitored and controlled to prevent polyperoxide formation, fisheyes improved considerably. e. New Solution Fast Catalysts Reference was made during the catalyst handling and storage discussions, that not only do the solution catalysts reduce the severe hazard of handling solid IPP, but give better conversion and cycles as well. No indication or which fast catalyst was made, however. f. Shortstop Testing Uniroyal is doing some testing to determine the effectiveness of isoprene in various concentrations and under different conditions as an emergency shortstop. Isoprene was reported at an earlier meeting to be the most effective shortstop for PVCTreactions. Uniroyal will make the test results available to the Vinyl Chloride Safety Association in unpublished form at a future meeting. X 0: a RSV 0000102 CO CO C BFG62218 VINYL CHLORIDE SAFI .
