TO i i ! Eeoruary 14, 19^9 ":C`J~7Y EEC:-: VAPOR CORPORATION CW TOXIC EEEECT OF CKLCRuNATZD J. J. Ecder - CHICAGO . J. R. Padlon R. A, Gkrcia S/ShW /7i7 1` 1/ S:an forwarded to me the note you received from Ed Gustaf ar.d che accompanying letter from T. Pujlwara, Managing Director, Ml con Vapor Generator Company, and to H. J. Schickedanz, General Manager, Vapor International. We have been adviced by our Japanese representatives of the bran oil poisoning of ruite a number of Japanese citizens that was attributed to Xar.eclor 400 (chlorinated biphenyl comparable to ER-2). '.'e assembled both medical and application data and sent it to our Japanese counter-parts as arguments for the cafe use of chlorinated biphenyl heat transfer fluid. Essentially, we said that there are certain toxic and systemic effects that can be brought about by the vapors of chlorinated bi phenyls. v/e did not rule specifically on the injestion limits cf this chemical. We also directed attention- to>the large r.umoer of applications in food processing that utilize The ml no 1 EE heat transfer fluid. V/e brought out very strongly the fact that these systems have been designed to minimize accidental contamination of food products with chlorinated biphenyls. I think we have a good track record here in the States using Thormir.ol ??. in these applications. However, it only seems a matter of time until the regulatory agencies will be look ing down our throats regarding the use of this material. Possibly, by the time this comes about, we will have com pleted feeding studies with chlorinated biphenyls that will allow ua more exact data than has been available in the past. As a matter of fact, .they're feeding this stuff to chickens now, but I have no specific results of these tests. I can only suggest that you attempt to put Gustaf's mind at case regarding the ''toxic" aspects of these chlorinated bipr.c.v/ls by claying down the medical reports and playing up proper system design. Look at the bright side for us in the heat transfer fluid cr.a of our business -- if the government closes us dov,n on cue use cf chlorinated biphenyls, we have two excellent fluids in Thermlnol 55 and Thermlnol 66, as well as, a proprietary fluid in Thermlnol 77 to exploit. Theminol 66 will certain ly be available in Japan according to recent information from our Engineering Department. _ HONS 096865 HARTOLDMON0012257 February 14, 1969 Pag a 2 A final caution Jim, please use the attached information with gome discretion. I certainly would not pass completed sets of this data to those asking the questions, but rather extract the essential points from this data, namely, the ruling on vapor limits as handed down by the Industrial Hygienist Associ ation, and a strong play on proper system design to prevent accidental contamination of food producta and procasalng material by chlorinated biphenyls.
