Dr. I.K. Inrun, Iswport, England. February 12th, 1954, Vo do not know what tha aaxinua allowabla concentration of iroolor la. Ona nllllgroa per enhle uter has been set up. He hove run anlula for about 60 days at 7 tinea this and found ions llrar dauga. Ha are now running this at a lower level. He have never found any liver trouble In any of the workers In our plant, but we watoh the oontrol of the fuaea la our eustouna' plants and always reooanend exhaust ventilation. Z an sure you realise that 1 ag par eobla aster la reoouanded for an 8-hour day for Indefinite periods of tlu. In painting a roon we hove found 1 - 2 ag for a day or so, but after that the level drops down to nothing. Hhat we were really worrying about was the possibility that a nan would 1 develop hepatitis, on an idiopathic, viral, or eerua basis and ou questioning ' would reoall iEst ha had painted a roon with iroolor paint and state that he had Bulled It very strongly. X an afraid than we night be eonvleted by association even though we ware sure one eould not get a level high enough to oause trouble. He have, however, bean concerned with the level of iroolor during spay painting, but X think that level eon only be detarnlned by actual neasuranents. Please do not worry about uklng na those quutleu because we certainly want you to have the entire picture about iroolor tcocislty. is soon u X get a report on tbs work at Kettsrlng, X will 1st you know.
