Ergonomic issues aside, the best thing to do in this situation is to tes t the hood as it's being used for containment.  If it can be demonstra ted that it's containing chemical vapors then you're well on your way to sa ying it's satisfactorily working.


I prefer smoke because you can get more information on hood flow pattern s and you can use it to teach operators about proper hood use, but a few dr ops of glacial acetic acid or concentratd ammonium hydroxide in a watc hglass can be used to check for containment as well.  You ca n tell right away if there are fugative emissions from the hood.


NB - HAc and Ammonia are not ANSI approved tests, your mileage may vary, see your local dealer for complete information etc.

Subject: [DCHAS-L] ADA Compliant Fume Hoods

Have any of you had experience with ADA compliant fume hoods being used by non-wheelchair bound personnel?  I have concerns that the shorter height (floor to work surface) of an ADA compliant hood wi ll be a problem when used by people who would stand in front of the hood to work.  Is there merit to my concern?

Thanks for any input that you can provide.  Pleas e feel free to reply directly to asimpson**At_Symbol_Here**
