It has been determined based upon an environmental-medical evaluation in the Grinding Room, Railway Division, of Plant 17, The Timken Company, (SIC-3743) Columbus, Ohio that skin irritation may result from direct contact with liquid Cimcool S23A coolant and respiratory irritation may develop from worker exposure to mists of Cimcool S23A coolant. This determination is based upon an evaluation of workers in the Grinding Room which included: breathing zone measurements of coolant mist exposure, pulmonary function tests, physical examinations, and medical questionnaires. While significant acute obstructive airways disease was not demonstrated during the evaluation, a relatively large proportion of workers developed upper respiratory irritation during the shift. A smaller number of workers developed eye irritation. Cutaneous examination of workers revealed an incidence of dermatitis greater than would normally be expected in a worker population of the size studied. Recommendations to improve the conditions contributing to skin and respiratory irritation have been made in this report.
