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 en vironmental 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 system* involving food or food-related products, animal feeds, pharmaceutical products, packaging materials involving any of such 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 environment cannot be prevented, you should replace Santovac 1 and 2 with non-PCB fluids immediately. P! ease contact your pump supplier for his ' recommended replacement product. DSW 020473 STLCOPCB4008400 Hr. H. V.
