The exhibit holds a Nov. 13, 1974 letter from the Medical Department's industrial hygienist reporting phase contrast microscopy results for ten October air samples from the Speedway acetylene cylinder operations. It also holds the Nov. 4, 1974 transmittal memo from R. P. Wooldridge and a handwritten sample summary sheet. The letter lists asbestos fiber counts of 0, 1 or less than 1 per ml for fibers longer than 5 microns, and says sampling can move to a quarterly basis.
