Fume Hoods

A chemical fume hood is a partially enclosed workspace that is exhausted to the outside. When used properly, hazardous gases and vapors generated inside the hood are captured before they enter the breathing zone. Fume hoods are tested by the safety office. If you suspect that the hood in your lab is not working, place a "broken hood" sign on the hood sash and call Frank Abell at (x7280).
