A Regulatory Perspective on the Recirculation of Exhaust Air.
NIOSH 1976 Feb:41-47
Federal and State laws on the recirculation of industrial exhaust air are in general permissive. Michigan's Department of Public Health stresses performance in recirculation systems; airborne contaminants must be held below their acceptable threshold limit values. The department evaluates on a case-by-case basis the type of system that would be most productive and safe, considering such factors as the existence of mixed contaminants in a plant and the possibilities for equipment deterioration. Adequate protection to the worker in a plant that recirculates exhaust air may be costly, but the technology for optimum system performance is there. The central role of the State regulatory department is to protect the health and safety of the employee, while assuring that the demands on industry are realistic.
