OSHA regulates Teaching and Research laboratories primarily under the Laboratory Standard (1910.1450). EH&S has developed a University Chemical Hygiene Plan that facilitates all laboratory users to be in compliance with the applicable regulations.

How to properly use a chemical hood (aka 'hood')

  • Before use check to see if the hood is pulling air properly
  • Place chemical containers at least a foot inside the hood
  • Use as few containers and pieces of equipment as possible
  • In situations where the floor of the hood will be more than 50% covered, work with EH&S to elevate the working surface. This will improve the capture of fugitive vapors and dust.
  • Do not use the hood as a long-term storage location
  • Keep the hood sash (the sliding glass window) as low as feasible while working, and close it entirely when not in use.

How to properly use a biological safety cabinet (BSC)

  • Before use check the gauge for adequate suction pressure
  • Never use flammable liquids or gases unless using as fuel for the flame sterilizer
  • Work at least a foot inside of the BSC opening
  • For BSCs with moving sashes, lower the sash as low as feasible
  • Decontaminate the BSC working surface when done working
