Monsanto Chemical Company 800 North Lindbergh Boulevard St. Louis 66, Missouri Attentions R. Emmet Kelly, M. D., Medical Director Dear Dr. Kellys Thank you for your communication of May 4, 1962. The patient to whom I referred in my original communication to the Seattle office informs me that the material that they use is Pydraul AC. The exposure is to a mist which apparently is given off from the four compressors that operate in the room in which he works. Because of this vapor or mist, the instructions are that they are to keep the doors open for adequate ventila tion, but this is usually not done because the room becomes too cold for comfort. The symptoms are those of a local irri tation relating to the respiratory tract, and they are relatively brief in duration and can be relieved by getting out in to the fresh air for a period of time. There is also complaint of irritation of the skin, and this is noted especially under the watch band. There are neither symptoms nor evidence of systemic intoxication. My patient informs me that all of the workers in the room have the same problem. His concern is largely whether or not a continued exposure to this material in this manner might possibly lead to toxic systemic effects. JEFieb DSW 018734 STLCOPCB4005278
