Three Good Reasons to Dispose of Old Compressed Gas Cylinders

  • You will reduce unnecessary hazards in the lab. Compressed gases have limited shelf-lives (certificates of analysis expire, purity is compromised) and cylinders can leak or rupture – especially corrosive gases, which can corrode cylinder components and build up pressure and possibly burst. That is why corrosive gases should be used within one year and why larger cylinders must be inspected and pressure tested every 5 years.
  • You will create more useable space – especially in fume hoods. Toxic and corrosive gases must be stored and used in fume hoods or other exhausted enclosures.
  • You will avoid extended cylinder rental charges or replacement cost if the cylinder is lost, missing or damaged, and do someone else a favor. Campus cylinders are limited and someone else may need a cylinder.
