Ventilation Shutdowns: Fume Hood and Biosafety Cabinet Use

Fume hoods and biosafety cabinets (BSCs) should not be used when the ventilation system serving the room, either supply air side or exhaust air side, is shut down. The personal protection provided may be compromised with inadequate ventilation. In addition, the product protection provided by a BSC may be compromised as well.

If you need to know more about on-site tests that you can do to check your BSC, contact Environmental Health and Safety at (206)543-0469.
