COMPRESSED GAS SAFETY

Compressed gases pose significant safety risks, so it’s essential to handle and store them properly to prevent serious incidents. See below for key safety requirements and best practices for working with compressed gas cylinders. Following these guidelines is critical for protecting yourself and others in the lab or workplace.

• Summary of requirements
  • Cylinders must be handled at high-energy sources. Always transport cylinders with the safety cap installed and use a cylinder cart. Do not roll them by hand along the floor or transport them on forklifts.
  • Always store cylinders upright and secure them using an approved lock-down device.
  • Always use the correct pressure regulator for the specific gas.
  • Do not store cylinders or lecture bottles with the regulator in place. If the regulator fails, the entire contents of the cylinder may be discharged.
  • CGA fittings differ for inert gases (e.g., He, Ar, N2), flammable gases (e.g., H2) and oxidizers (e.g., O2, N20).
  • Compressed gas cylinders, which contain acutely toxic gases, must be stored in a designated area.
  • All compressed gas cylinders must be clearly marked with the correct chemical name.
  • All cylinders should be labeled to indicate if the container is full or empty.
• Training
  • Individuals using compressed gases must be trained in the safe use of the material and pressurized systems. Primary responsibility for specific operations training is with the employee's supervisor. Environmental Health & Safety may be consulted as necessary.
  • Hazard Communication or Chemical Hygiene training must be provided by Environmental Health & Safety. View our training page.
