May 8, 1964 Mr. 0. Lay Laboratory Supervisor Anaoonda Aluminum Company Mo. 13th St. Terra Haute, Indiana Dear Mr. Lay1 I am enoloslng two bulletins and our standard toxicity and safe handling information sheet on Pydraul g-q. As you can see from these, Pydraul F-9 is a relatively innocuous substanoe. Patch testing las indicated that P-9 is not a primary irritant or sensitizer and this has surely been borne out by our experience. We have had no oases of irritation that have been oalled to our attention. Pydraul F-9 is, of course, a solvent and, as is the case with many other solvents, prolonged akin contact would deplete the natural oils in the skin which might cause dryness and cracking. For this reason we advise that following prolonged or repeated skin contact this material should be washed off thoroughly. If! can help you with any further information, please let me know. Very truly yours. MNJmJb M. N. Johnson, M. D. Assistant Medical Direotor DSH 018838 STLCOPCB4005382
