    1. Fume Hoods
      1. Only material and equipment directly related to the experiment in progress is to be kept in the fume hood.
      2. Each fume hood is marked with a working sash height mark. Work requiring fume hood protection shall not be conducted with the sash opened beyond that mark.
      3. Hoods with sashes opened to the working height must have a ventilation flow rate > 60 linear feet per minute.
      4. Fume hoods should be checked by the user each day prior to use. The controller should have a green signal, and there should be evidence of air flow.
      5. Fume hoods should be inspected and tested quarterly by the Chemical Hygiene Officer during the months when the hoods are in use.
      6. Work/experiments in a hood will be discontinued whenever maintenance or repair of the system is being performed.
      7. Fume hoods will be inspected and tested after repairs are made to the supply/exhaust system.
