Abstract
The authors' studies in the reinforced plastics industry have indicated that the prevention of eddy currents over the mold is of crucial importance when exposure to styrene is controlled with directed air current. This means that good exposure control can be obtained only by appropriate ventilation design of individual work sites. Exposure to styrene also can be maintained below the level of 50 ppm by the use of exhaust ducts having exhaust rates of over 0.1 m3/sec/m2.
