Kinzey - EXO May 20, 1974 INDUSTRIAL HYGIENE SURVEY ASBESTOS SAMPLING STUDY - February 19, 1974 Attached is a copy of the Asbestos Sampling Study which we discussed over the phone on Friday, May 17, 1974. I have made the appropriate corrections and regret that I was not available last week to resolve your questions. This memorandum certifies that letters informing employees of over-exposure to asbestos fibers were held up at my request as a result of errors in my previous report. I hope this resolves the situation and if there are any additional questions, please do not hesitate to call me. HMC/mfJ Enclosure H. M.
