Debbie, Do you have the regulatory reference for this requirement? Thanks! Rachel E.

We've been installing monitors on our fume hoods, here, for about 10 years so compliance hasn't been too onerous. But it is taking time to get old hoods retrofitted. About 250 to retrofit out of about 1600 hoods. I agree with the requirement myself. Though I have seen a pipette tip jammed into the "mute" button on the alarm to shut it up when the hood is operated incorrectly .

One idea we're talking about is to request that the electronic flow alarm systems NOT be installed on new hoods. Our experience is that these are not well understood by laboratory worker and the alarms are often silenced into uselessness in many laboratories. We would substitute a campus wide standard "tell tale" (i.e. a fancy Kimwipe) to be taped to the bottom of the sash so that people could assess flow in a quick, uninterruptible way. I wonder if other campuses have developed this idea and what your experience has been along these lines? Thanks for any information. - Ralph Ralph Stuart, CIH Environmental Safety Manager University of Vermont Environmental Safety Facility 667 Spear St. Burlington, VT 05405 rstuart**At_Symbol_Here** fax: (802)656-8682
