'---- ) ^pvinod Metal Prodjuite^ 29501 ClayTorTAvenue Wlckllffe, Ohio 44092 Dear Mr. Rossello: This letter will confirm our telephone conversation concerning Santovac 2 vacuum fluid. As Indicated on their labels, Santovac 1 and Santovac 2 contain polychlorinated biphenyls (PCBs) of various types. As you are aware, PCBs have Increasingly come under the scrutiny of various governmental agencies and scientific laboratories. In some studies, certain PCBs have been found to be persistent, an environmental contaminant and possibly Injurious to certain forms of bird, aquatic and animal life. Accordingly, It Is Important that PCBs 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, vaporization or otherwise. Some specific applications where these fluids should definitely not be used are In vacuum systems Involving food or foodrelated products, animal feeds, pharmaceutical products, packaging materials involving any of such Items and buildings where any of these Items are manufactured or stored. If your vacuum system Involves any of the mentioned applications, or if your system Is such that entry into the environment cannot be prevented, you should replace Santovac 1 and 2 with non-PCB fluids Immediately. Please contact your pump supplier for his recommended replacement product. MONS 09428? Nr. Rossello Ootober 11, 1971 Pag* Two Used Santovao 1 and 2 should be returned to Monsanto Company, W. 0.
