Papageorge October 9, 19','1 Mr. A1 3atey Pr oject Arohltact Kaiser Engineers Kaiser Center Galt land, Ca.lir, 9460^1 Dear Al: Ab requested in your letter of September 23 to D. R. Hansen, the primary reason for our discontinuing sale if Thermlnol 71? fluids into new heating systems Is to control the amount f polychlorinated biphenyls (PCBe) in our environment. Thermlnol PR fluids c ntaln PCSs. This action is prompted by recent Investigations by governmental and scientific research laboratories which show certain pc3s t be a persistent environmental contaminant and, possibly, inju rious t > certain forms of bird, aquatic and animal life. PCBa were Involved in an incident outside the U.S, where In gestion of a food product contaminated by this chemistry caused akin disease and sympt >ma of poisoning. In the states, PCB content in various food and feed stuffs have been widely publicized in recent weeks. Distribution of PCB containing products has been curtailed and, at this time, a House Bill (H.R. IOO85) is in committee callin', for a ban on delivery of PCB into c mmsrce. In view of the above, we will not sell PCB containing Thermln 1 PR fluids into any new system, whether designed to use the product or not. The "hold harmless" letter does not, then apply to the case of a nevi syater. Por the Oakland Towers heating system, we can only Buggest the use of Thermlnol 66 in place >f Thermlnol PR-1 MOWS 092344 -2- IJnf >rtunately, Thermln ! 66 Is n;t a fire resistant fluid and >ur J lnt attempt to galr; its apprval f r this applieati r haa not been successful. Any qualiflcatl w of the use f Therminol 66 in c mmercial buildings by a non-Monsant; testing agency such as UL or PW would Involve a minimum of eight weeks. We are seeking appro val to initiate these tests. In the Interim, the data available on Therminol 66 as related to fire risk lo that presented to the California State Klre Marshall on August 31. You participated In thlB meeting and have copies of the data presented. Vapor pressures at the flash and fire prints appear on the tabulation of physical pr .perty variation with temperature. Concerning aut ' Ignition of Therminol 66 saturated lnsulatl n, I can quote data from Atomic Energy of Canada, Limited where the temperature requirement to cause Ignition is greater than 327 P. The Installations using Therminol 66 are primarily industrial. H wover, two that circulate hot fluid Inside occupied buildings are: Amoco Research C rp, Naplervllle, 111. (312) 420-5111 Contact: Wm. Taylor E. Saunders Whlteshell Nuclear Facility Plnawa, Manitoba, Canada Contact: S. Hatcher Other Installed systems In your area: Chevron Chemical Co. Richmond, Calif. Harvey Aluminum Co. Johnday, Washington Ashland Chemical C-. Oakland, California Perhaps contact with these Installations will assuage the ap prehensions of the Oakland PIre Marshall.
