Effects of face velocity, flanges, and mannikin position on the effectiveness of a benchtop enclosing hood in the absence of cross-drafts / Steven E. Guffey, Nir Barnea

Sumario: Although enclosing hoods are often deemed the most effective type for industrial processes, there is little published research concerning simple enclosing hoods similar to those used in industry. This study investigated the effects of face velocity, mannikin position, and flange angle on exposure to a mannikin standing at the face of an industrial benchtop enclosing hood. Sulfur hexafluoride was released at low velocity inside a plain enclosing hood located on a tabletop
