The Recirculation of Exhaust Air.
NIOSH 1976 Feb:135-143
The decision to use recirculated air should be made for each individual operation. The final decision should be based on data gathered under use conditions. The Southwest Research Institute grouping of chemicals has little merit for determining if recirculation of exhaust air is a feasible engineering approach for conserving energy and the protection of employee health. Data gathered in a vinyl-chloride (75014) copolymer film extrusion plant demonstrates that acceptable workroom concentrations can be maintained with 90 percent recirculation of air. Energy savings of 30,000 dollars per year are achieved.
