Th Interpretation of the toxic properties of a eompound* however, determin whether r net there Is any hazard associated with the specific use f a compound. To ay knowledge, there is no hazard involved in the m% off transformer containing Arcelor as a substitute for other materials To my understandings in the United States this application of Aroclors is widely accepted and has net resulted In any difficulty from e toxicological standpoint* I cannot state whether or net a flash discharge might generate phosgene I believe * however,, that any phosgene e generated would be in a very email proportion to the total smoke and fumes resulting from the discharges In instances where Areolae as a heat exchange medium, ha been subjected to fire and high temper ature after a leak in equipment, the clouds of breakdown products have been- highly irritating but probably no mote so than on would expect from the burning of any type of industrial oil or chemical. I (m sure that Mr* Benignu will answer your questions relative to th offset of Arcelor fen insulating material^, when he returns from Ms vacation next week. As you indicated, we r watching the use of th Aroelor as plasticizers in emulsion paint We do net recommend that they be used in paints which might be applied in confined or m1ventilated areas, particularly if the paints might b used ra heated surfaces. Is you stated, this is a es worrying about th exposure of painter* who might apply such materials day in and day out rather than til worrying about those who night occupy th room during or shortly after the paint hag been applied* I IPWigf IN IV Wheeler MOWS 095187 DEPOSITION EXHIBIT it \<Sm~ TOWOLDMONOOQ7916
