Compressed Gas Safety

One of the most common safety hazards in all labs are compressed gas cylinders. Handling and storage of these cylinders is also one of the most common EPA and OSHA violations. The following simple guidelines will help ensure a safe lab.

Flammable, Asphyxiant, Toxic, Corrosive, Oxidizer, Pyrophoric and Cryogenic gases require additional safety measures. Contact Environmental Health and Safety for training and information.

Cylinder Use

  • Use a 2 stage regulator made for that gas.
  • Do not alter, adapt or use Teflon tape on regulators (Teflon tape can only be used on threaded connections).
  • Leak test fittings, piping and connections before work begins.
  • Leave 25 psi in cylinder. Do not empty cylinder completely to prevent backflow of contaminants or air.
  • Mark cylinders "MT" or "EMPTY"; store separately from full cylinders.

Read the EH&S Policy 1-5 "Compressed Gas and Cryogenic Fluid Handling, Storage and Disposal" for additional information.
