Fume hoods are used to ensure a safe work environment. Fully understanding the importance of this piece of equipment can help laboratory employees stay safe and function properly. Fume hood safety should be taken very seriously. 


  • Regularly review the manufacturer’s recommended safe practices for your fume hood
  • Make sure the selected enclosure is appropriate for the work you intend to do
  • Minimize drafts and movement in front of the hood and locate the hood away from heavy foot traffic, doorways, and HVAC ventilation grates
  • Work a minimum of 6” inside the hood
  • Wipe up spills immediately
  • Elevate equipment above the worksurface to not inhibit air flow
  • Adjust the sash to the smallest opening possible within use. The sash glass is a physical barrier to protect the user’s breathing area
  • Close the sash when the hood is unattended
  • Always follow the manufacturer’s guidelines regarding routine maintenance and calibration


  • Place your head or body inside the hood, the fume hoods interior should always be considered a contaminated space
  • Keep your work within the first 6” of the sash or perform work outside of the sash
  • Obstruct air foil or baffle as this could cause loss of containment
  • Block air flow with equipment
  • Use for storage, keep unneeded items to a minimum
  • Keep sash wide open during use
  • Remove any of the hood’s components
  • Place flammable solvents near heat sources, flames, or sparks
  • Use with biohazards or perchloric acid which require specialty equipment specifically designed for their use

With proper use, cleaning, and routine maintenance the chemical fume hood will prove to be a valuable safety feature in your laboratory. Consult your lab Safety Officer for a reference on what type of safety equipment is required or if you have any questions or concerns.
