Fume Hoods

Standard Fume Hoods:

For fume hoods to work properly you must maintain proper air flow. To properly protect yourself:

  • Always keep the fume hood sash at the lowest possible height while still being able to work comfortably or below the indicated max sash height
  • When not in use keep the fume hood sash closed
  • Do not store chemicals or equipment in the fume hood. Only use the lower cabinets for storage
  • Keep all work at least 6 inches away from the front and back of the hood and if possible raised up
  • If the low-flow alarm goes off stop work immediately and notify the lab PI or call Facilities and Operations (492-4833)

When you do not follow the procedures above, you reduce the airflow to the entire line of fume hoods. Even though the hood in your lab may not be heavily used, the other hoods may be used daily. Your simple act of leaving the sash wide open may be putting other EAS workers in danger because the fume hood in their lab is not drawing as efficiently as it could.

HSE tests all the fume hoods on an annual basis. There are regular maintenance or emergency shutdowns of the fume hoods so that the air handler unit can be repaired or maintained. These notices are sent out by email to the entire department.


The lab should stop chemical activities until the maintenance is complete.
