I bccf*C. L. BRADFORD H. R. FORD - 1070 October 3, 1971 Mr. Robert Curd d Curd Hntsrprine J 211 Xriquois Court Charleston, South Carolina 29406 Dear Mr. Curdi This latter confirms your telephone conversation with Mr. Moore on October 1 concerning Curd's use of the Santovac 2 vacuum pump fluid. As indicatsd on their labels, Santovac 1 and Santovaa 2 contain polychlorinated biphenyls (KBs) of various types. As you are aware, FCBa have increasingly come under the scrutiny of various governmsntal agencies and scientific laboratories. In some studies, certain KBs have been found to be persistant, an en vironmental contaminant and possibly injurious to certsin forms of bird, aquatic and animal life. Accordingly, it is important that KBs be kept out of the food chain. We want to remind your firm of the extreme care that must be taken by users of Santovac 1 and Santovac 2 fluids to prevent any entry into the environment through spills, leakage, use, disposal, vaporisation or otherwise. Some speaifie spplications where these fluids should definitely not be used are in vacuum systems involving food or food-related products, animal feeds, pharmaceutical products, packaging materials involving any of suah items and buildings where any of these items are manufac tured or stored. If your vacuum system involves any of the mentioned applications, or if your system is such that entry into the environsmnt cannot be prevented, you should replace Santovaa 1 and 2 with non-PCB fluids Immediately. Please contact your pump supplier for his reeoMsended replacssmnt product. MONS 094156 Mr. Robert Curd Curd Enterprise October 5, 1971 Page 2 Used Santovac 1 and 2 should be returned to Monsanto Company, w. G.
