Fume hoods are a necessary piece of engineered equipment to protect users and occupants from possible chemical exposures. There are approximately 700 fume hoods on campus and outlying areas. These hoods are inspected and certified annually by EHS personnel. Fume hood function and hygiene are among the inspection criteria. A certification sticker is present if your fume hood is commissioned and part of the annual hood certification program. If your fume hood does not have the white certification sticker applied to the sash or if it is missing, please call EHS so that it may be included in the annual inspection and certification process. All new fume hood installations must be commissioned or certified by EHS before use. This program also recommends face velocity and unit specifications based upon testing, product data and operational standards.
