Fume Hood Safety Tips

  • Verify the exhaust system is operating before each use.
  • Close the sash as much as possible when working at the fume hood – use the sash as a face shield.
  • Close the sash completely when not working at the fume hood.
  • Avoid placing your head inside the fume hood.
  • Avoid rapid movements in front of and inside the fume hood.  This can cause air currents drawing contaminates out of the fume hood.
  • Avoid raising the sash(s) too quickly.  Raise the sash at a moderate rate and allow the air velocity to increase or the variable air volume system to react to the door movement.
  • Never work with sashes set higher than the established working height.  Contact safety or air balancing staff if the safe working height is unknown.
  • Never work with both sashes open on a walk-in hood.  The lower sash is for setup access only.
  • Turn on lights.  Good illumination will reduce eyestrain.
  • Set up apparatus as close to the back as possible.  In no case should apparatus be closer than 6 inches (15 cm) from the door.
  • Do not block airflow.  Raise large object 2 inches (5 cm) off the counter by placing them on blocks.  This allows airflow underneath and prevents stagnant areas.
  • Never store large quantities of chemicals in the fume hood.  Chemical containers block airflow and create unnecessary hazards.  Use cabinets designed to store chemicals instead.
  • Do not over ride an alarm by manipulating the mute button.
  • Clean up chemical spills as soon as possible.  Avoid damage to countertops and buildup of large quantities of vapors.
  • Ground all electrical equipment.
  • Avoid excessive heat within the fume hood.  Special hood configurations are available for high heat situations.
  • Baffles should be adjusted by qualified airflow experts or safety officers only.
  • Perchloric acid hoods should have the wash down system operated at least once per day until a thorough cleaning is accomplished.  5-15 minutes will probably be sufficient depending upon flow rates achieved by the in-duct portion of the system.
  • Never allow the area immediately in front of a fume hood in use to become a traffic area.  Others walking by the hood face will adversely affect containment.
  • Variable Air Volume (VAV) system:  Such a system will reduce the amount of temperate air lost to the outside by varying the exhaust volume from the fume hood automatically based on the position of the sash.
  • Air flow monitoring devices (alarms): These are available to alert the user that there is insufficient airflow for proper containment.
  • A fume hood that is clean and orderly is safer and easier to “shut down” in an emergency, in addition to being more attractive in appearance.
