A recent survey of our chemistry building's fume hoods found at least 50% of the front edge air foils had been removed, presumably by the occupants. It appears that most of them were removed in order to attach gas cylinders to the front of the hoods. I understand how bad an idea this is from a safety and aerodynamics point of view, but I wonder if this high rate of "user modification" is trying to tell us something? Are the users likely to be better off with the air foils removed despite the consequent decrease in containment? Or is this simply ignorance on the part of the fume hood users? Any comments appreciated. - Ralph Ralph Stuart, CIH Environmental Safety Manager University of Vermont Environmental Safety Facility 667 Spear St. Burlington, VT 05405 rstuart**At_Symbol_Here**uvm.edu fax: (802)656-5407
