Abstract:
Face velocity is the standard variable used to test the performance of laboratory fume hoods. A quantitative testing method developed by Caplan & Knutson involves the measurement of tracer gas leakage out of a hood. Use of that method identified parameters other than face velocity that seemed to affect hood performance. In this study, a new testing method (Scott Method) was developed to incorporate hood parameters identified by Caplan & Knutson with face velocity measurements to generate a more comprehensive hood performance test method. The Scott Method consists of a semi-quantitative rating scheme that assesses the effects of traffic, diffuser velocity, equipment in the hood, and variation in face velocity on hood performance. The performance of 10 laboratory fume hoods was measured by the three methods; the Caplan & Knutson method was used as the measurement standard. The study hypothesis was that the Scott Method would yield a better prediction of hood performance than face velocity alone. This study suggests that prediction of hood performance by the Scott Method was not significantly improved relative to the use of face velocity alone.
