Gas, Compressed & Toxic

All compressed gases (which include toxic gases) present physical hazards due to their high pressure.To learn about  management of compressed gases, see the EH&S publication, Compressed Gas Cylinders: Proper Management and Use. Units wishing to order and maintain gases, must contact EH&S for a hazard evaluation and written purchase approval, before ordering any gases.

Toxic gases are gases that::

  • Cause significant acute health effects at low concentrations
  • Have a National Fire Protection Association (NFPA) health rating of 3 or 4
  • Have low occupational exposure limits, or are pyrophoric. Contact the Office of Environment, Health and Safety (EH&S) to advise them of your plans to acquire the gas. Refer to the EH&S Campus Toxic Program Fact Sheet, which provides the basics about what you need to know.

Such gases may be available as:

  1. Returnable cylinders.  Ask suppliers for a list of available gases.
  2. Non-refillable, non-returnable gas cylinders.  EH&S discourages buying non-returnable cylinders, when other options are available, because EH&S must dispose of any full, partially full, and empty cylinders,
  3. Lecture bottles, which are typically disposed of as hazardous waste; please visit the EH&S website for more information.
