Technical Critique of Recirculation Criteria.
NIOSH 1976 Feb:25-39
A critique of a report on the development of criteria for the recirculation of exhaust air is given with the viewpoint that regulatory agencies should not take an unduly restrictive approach to recirculation of air. Considerations include developing criteria that are applicable to the real world, reliability of the systems, flexibility of recirculation systems, failure of recirculation systems, threshold limit value and eligibility of substances for recirculation, classification of substances, air cleaner for particulates, air cleaning equipment available and models of redundant air cleaners and of air cleaning with a bypass.
