c % i t t t% e [Re-typed for clarity] July 19, 1956 Mr. Elmer F. Wheeler Assistant Director, Medical Department Monsanto Chemical Company St. Louis, Missouri . Dear Mr. Wheeler: With respect to your letter of July 27, I greatly appreciated the telephone call from Mr. Benignus. However, I will greatly appreciate further information as follows: copies of toxicity data including physical and chemical properties of both transformer and capacitor Inerteen which would be your Aroclor 1260, 1254 and 1242. Mr. Benignus indicated in his telephone call that you were evaluating Inerteen concentrations with the use of the Willson chlorinated hydrocarbon equipment. I will greatly appreciate detailed information concerning the temperature of the furnace and the amount and . nature of platinum used in the furnace for making these determinations. A number of years ago the experiments with this furnace, which was one of the first models, were found it to be unsatisfactory. I am wondering what information you have to indicate the use of this furnace is adequately measuring the amount of Inerteen in the atmosphere as well as furnace temperature and flow rate, of air through the furnace, amount and shape of platinum within the furnace. . Mr. Benignus stated that the maximum allowable concentration for either of these Aroclors should not exceed about 3 milligrams of Aroclor per guide meter of air. Does this apply to any of the 3 Aroclors indicated. Any additiional information that will be of value to me in association with Aroclor such as skin reaction data will be greatly appreciated. cnnnnR2 WATER PCB-SD0000026303 Would there be any detrimental (illegible) if it would be used as a hydraulic (illegible) . reaction fluid in Sincerely yours, WESTINGHOUSE ELECTRIC COR?.
