Abstract
Guidelines for an approach to recirculation of industrial exhaust air are given in a paper presented at a symposium held October 6-7, 1977 in Cincinnati, Ohio. The level of toxic materials in the workplace often can be reduced while conserving energy. With the reduced availability of energy sources at any price, significant savings may accrue from the use of recirculating exhaust systems where large volumes of makeup air must be conditioned to maintain worker comfort and process control. Industrial exhausts often contain toxic contaminants of unknown type and at unknown concentration levels. When these exhausts are emitted into the outside atmosphere, the health impacts on employees within the plants are generally small. Recirculation implies cleaning such exhausts and delivering them back into the plant, a procedure which may lead to adverse health impacts when: 1) the planned level of cleaning is inadequate; 2) contaminants in the exhaust are not cleaned because their existence is not known; 3) the air cleaner fails; and 4) the exhaust contains contaminants which should be eliminated from the breathing environment as completely as possible. An outline for avoiding such situations is presented.
