A December 12, 1974 letter from Union Carbide industrial hygienist Leo J. LaFrance reports phase contrast microscopy results for eleven November air samples for asbestos taken at the Linde Speedway Factory in Indianapolis. The results range from 0 to 2 fibers per ml longer than 5 microns, and he suggests sampling could be reduced to a quarterly basis. The exhibit also contains R. P. Wooldridge's December 3, 1974 cover memo forwarding the samples and a handwritten sample summary sheet.
