KA5 0~ - (1 LETTER TO ALL THERMINOLFR USERS Office of President . XVZ Company Dear Customer: We are contacting your firm as a user of one or more of -the i TherminolFR series heat transfer fluids. The TherminolFR series includes TherroinolFR Lo-Temp, ThorminolFR-0 and Therminol FR-1. As Indicated on the labels attached to the containers, the TherminolFR series contains polychlorinated biphenyls (PCB) of various types. As you are undoubtedly aware, the PCB concentration in our environ ment has increasingly come under the scrutiny of various govern mental 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 very important that PCBs be kept out of the food chain. We would like to take this opportunity to remind your firm of the extreme care that must be taken by all users of PCB-containing products to prevent any entry into the environment through spills, leakage, use, disposal, vaporization or otherwise. Some specific applications where the use of the TherminolFR series should definitely be avoided are in heat transfer systems Involving v food or food-related products, animal feeds, pharmaceutical products. 0*i77(>79 PCB-ARCH0744601 1 i 2 - - iI packaging materials involving any of those items, and buildings where any of those items are manufactured or stored. If your system involves food, feed, packaging or any of the other mentioned applications or if your system is such that entry into the environment cannot be prevented, then we urge you to replace the TherminolFR series with heat transfer fluids which do not contain PCB, such as Monsanto's Thermino3.55 of T-66. Would you please contact your Monsanto Fluid Specialist if you determine that the TherminolFR fluids should be replaced. We recommend that you give very careful study to eliminating any possibility that the TherminolFR fluids in your systems may ; reach the environment. For your reference we are enclosing a copy of our technical bulletin entitled "How to Keep Your TherminolFR System Leak-Free"; that bulletin includes the shipping instructions for return of ThermlnolFR fluids to Monsanto for Incineration. Sincerely, J.R. Fallon, Product Manager Heat Transfer, Dielectrics, and Process Fluids 0472680 PCB-ARCH0744602
