This research addresses the relationship between laboratory fume hood performance and various aspects of its design and use, with an emphasis on the effects of worker movements and work practices. The objectives of this study were (1) to investigate the effects of various factors, particularly worker movements, work practices, and environmental conditions, on laboratory fume hood performance, and (2) to develop a new quantitative test method for laboratory fume hood testing.Subjects--Topical Terms:

This research addresses the relationship between laboratory fume hood performance and various aspects of its design and use, with an emphasis on the effects of worker movements and work practices. The objectives of this study were (1) to investigate the effects of various factors, particularly worker movements, work practices, and environmental conditions, on laboratory fume hood performance, and (2) to develop a new quantitative test method for laboratory fume hood testing.

This dissertation consists of three parts: a review of published quantitative experimental studies on factors affecting laboratory fume hood performance (Chapter 2 and Chapter 3); effects of upper body movements, work practices, and environmental conditions on laboratory fume hood performance (Chapter 4); and a new quantitative method for testing laboratory fume hoods (Chapter 5). Chapter 6 summarizes the findings of each part of the dissertation.

The review study found that hood failure was greatly affected by the presence of a mannequin/worker, distance between source and breathing zone, sash height/sash opening, and hood testing method. Results suggest that the use of face velocity may not be an effective evaluation tool for hood performance in the absence of other information.

The upper body movement and work practice factors tested in this study affected the measured concentrations in front of the worker. Sash opening was found to be the most important factor among the tested factors. Cross flow reduced the concentrations in front of the worker although it may result in bystander exposures within the lab. Upper body movement greatly affected hood performance reflecting the complex nature of airflow patterns and air contaminant transport inside the hood. Thermal load and hood clutter were relatively insignificant factors.

A new quantitative method using dry ice, warm water, and a carbon dioxide direct reading detector was developed for testing in-use laboratory fume hoods. This method is much easier to use, cheaper, and less time consuming than the ASHRAE 110 tracer gas test method and it may be used as an effective evaluation tool for hood performance. The hood test results using the dry ice method were comparable to the results using the ASHRAE 110 method under the specified conditions and test setup.
