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
