Title Validation of a method to determine a protection factor for laboratory hoods
Bibliographic information Aug. 1982, Vol.43, No.8, p.596-601. Illus. 2 ref.
Abstract The method described determines a hood's relative efficiency for containing a vapour released at a known rate inside the hood. Measurement of vapour contamination in the breathing zone of a mannequin standing at the face of the hood allows determination of the effects on hood performance of air supply, turbulent room air, hood location, hood sash configuration or worker position. The test method and protection factor calculation is valid for different hoods and is a valuable tool for comparison of laboratory hood systems.
