May 8, 1964 Mr. G. Ley Laboratory Supervisor Anaconda Aluminum Company No. 13th St. Terre Haute, Indiana Dear Mr. Ley: I am enclosing two bulletins and our standard toxicity and safe handling information sheet on Pydraul P-Q. As you can see from these, Pydraul F-9 is a relatively innocuous substance. Patch testing has indicated that F-9 is not a primary irritant or sensitizer and this has surely been borne out by our experience. We have had no cases of irritation that have been called to our attention. Pydraul F-9 is, of course, a solvent and, as is the case with many other solvents, prolonged skin 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. Ifl can help you with any further information, please let me know. Very truly yours. MNJimjb M. N. Johnson, M. D. Assistant Medical Director ! DSW 586378 i i 1 STLCOPCB4091712
