S. A. D'Arrnond T. R. Robinson, M.D. Medical Evaluation of Men Fabricating (Asbestos) Caustic Cell Diaphragms July 11, 1975 Industrial Hygiene evaluation of the fabrication of asbestos - containing diaphragms for caustic chlorine cells can be summarized as follows: 1. Asbestos levels in the breathing zone of workers doing this work are substantially below the present and proposed "TLV" levels, and hence should be safe for continuous work, exposure. 2. Conditions of fabrication are stable to the point that repeated environmental sampling should not be necessary unless changes are made in the procedure. In view of these findiggs, it is my medical judgment that special "asbestos examinations1' are not medically indicated for workers involved in this procedure. As a matter of good occupational medical practice, these workers should continue to be offered periodic comprehensive medical examination at intervals of approximately 3 years, as in the past.
