Fume Hoods and Laboratory Ventilation

The fume hood is often the primary control device for protecting laboratory workers when working with flammable and/or toxic chemicals. OSHA’s Laboratory standard (29 CFR 1910.1450) requires that fume hoods be maintained and function properly when used.

Environmental Health and Safety (EHS) conducts routine performance testing on fume hoods annually to verify they are operating properly and have the appropriate face velocity to capture airborne hazards. An inspection label with the performance test date and results is posted on the front of the fume hood next to the sash. Performance tests expire the following year at the end of the inspection month indicated on the label. If you find that a fume hood performance test has expired, contact EHS at safety@ksu.edu or 785-532-5856.

If you find that your fume hood is not functioning properly or if an alarm will not reset, submit a service request through Facilities Customer Services (785-532-6389 or /facilities/request/) to have the hood repaired.

If your fume hood airflow alarm activates, close the sash and wait a moment and then reopen the sash to your working height. If the alarm continues, stop using the hood, close the sash and promptly contact Facilities Customer Services at 785-532-6389 to have the hood repaired.
