Letter from an industrial hygienist to W. J. Ziemba summarizing an August 6, 1975 investigation of areas at the Tarrytown site. It reports a personal air sample for an operator cutting and weighing asbestos samples at under 1 fiber per ml, and a carbon fiber sample of about 12 fibers per ml against a suggested limit of 0.5. It also covers amine and fish-toxicity information and computer room noise, and encloses an amine air-sampling method and a table of amines.
