Oc'jluy jta [ \"'"i . | May 2, 1967 Mr. John Oliver Manitoba Rolling Mills Dox 2SOO Selkirk, Manitoba CANADA Dear Mr. Oliveri This supplements our telephone conversation on the Pydraul hydraulic fluids. I am not sure whether you are interested in Pydraul 312 or Pydraul ISO, so let mo give you our toxicological Information on both. This is, as 1 understand, for your transmittal to the Compensation Board of the Province of Manitoba. I am unable to give you the exact formulation of Pydraul 312. It contains aromatic chlorinated hydrocarbon, a petroleum-type _ oil, and an alkyl phosphate ester. This latter is not TCC. -- TC r We believe that the decomposition products at elevated tem peratures would be chlorine or hydrochloric acid mist, CO, and 002 Aa auh they would be Irritating to the lung If pro longed or repeated exposure would occur. Pydraul 150 is a somewhat similar compound with, however, a larger proportion of the alkyl phosphate eater and a lower percentage of the chlorinated hydrocarbon. We think the response of respiratory contaot to the decomposition produots of this Pydraul would be the same as Pydraul 312. If you have any further questions, please let me know. Sincerely, REK/ln R. Emmet Kelly, M. D Medical Director MOWS Q90B2Q
