Title A performance test for laboratory fume hoods
Bibliographic information Oct. 1982, Vol.43, No.10, p.722-737. Illus. 7 ref.
Abstract A performance test was developed, using the measured concentration in the breathing zone of a worker (mannikin) at the face of the fume hood when known amounts of tracer, mixed with air, were released in the hood. The test method yields a performance rating which includes all parameters, e.g., the influence of room air currents and the presence of a worker, not just face velocity. A performance rating incorporating the tracer gas release rate in litres/min, the as-used-in-the-laboratory conditions, and the control level, in ppm, in the breathing zone of the worker, was determined. Tests conducted in the absence of a mannikin yielded much lower control levels than with the mannikin present.
