Recirculation of industrial exhaust air, symposium proceedings, October 6-7, 1977, Cincinnati, Ohio.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Contract 210-77-0056, 1977 Dec; :1-158
A study sponsored by NIOSH to develop guidelines for recirculation of industrial exhaust air to assure the health and safety of employees in the workplace was reviewed at a symposium held October 6-7, 1977 in Cincinnati, Ohio. Special attention was given to the needs of industry and the system designer. Topics covered included the logic and procedures to evaluate the assumption, with certain restrictions, that all chemicals are potentially suitable for a given recirculation process situation; the needs of industry and the system designer; contaminant monitoring; and recirculation practices and research in Sweden. It was concluded that recirculation is feasible to conserve energy provided certain specific precautions are taken to protect the health of the worker. It was recommended that additional technical information be obtained which would concentrate on real life experiences in attempting to validate the guidelines developed and would include results of industry studies.
