Compressed Gases

How do I order Gas Cylinders?

Just like any other purchase, you order gases through the Stockroom by requisition. They can give you current pricing and sizes, and find custom gases for your research and instructional needs.

  • Empty gas cylinders can be brought down to either Ford or Sabin-Reed loading docks.
  • They must be transported by cart, which are available to borrow in both locations.
  • Please make sure that cylinders have caps on at all times when not in use.

How do I handle & Store Gas Cylinders?
The company AirProducts publishes a nice guide to handling and storage (AirProducts Gas Page)

From the Chemical Hygiene Plan (CHP 3.7)

Special systems are needed for handling materials under pressure. Cylinders pose mechanical, physical, and/or health hazards, depending on the compressed gas in the cylinder.

  • Cylinders with regulators must be individually secured. Only cylinders with valve protection caps securely in place may be safely gang-chained (chained in groups).
  • When storing or moving a cylinder, have the valve protection cap securely in place to protect the valve stem.
  • Cylinders must be secured in an upright position at all times. Use suitable racks, straps, chains, or stands to support cylinders against an immovable object, such as a bench or a wall, during use and storage.
  • Use an appropriate cart to move cylinders. DO NOT MOVE CYLINDERS BY ROLLING THEM!
  • Never bleed a cylinder completely empty. Leave a slight pressure to keep contaminants out.
  • Oil or grease on the high-pressure side of an oxygen cylinder can cause an explosion. Do not lubricate an oxygen regulator and only use an oxygen-approved regulator.
  • Always wear goggles or safety glasses with side shields when handling compressed gases.
  • Check cylinders, connections, and hoses regularly for leaks.
  • Always use a regulator sold for use with the specific gas; adapters may only be added on the downstream (low pressure) side of the regulator. All fittings, hoses, and other materials in contact with the gas should be compatible.
  • When working with a toxic, flammable (not including ‘house’ natural gas already plumbed into the labs), corrosive, or reactive gas is planned, prior approval by the ICHC is required. These gases may need to be used and stored with local exhaust ventilation such as a gas cabinet designed for that purpose and require purge systems, regulators, or other equipment installed according to the manufacturer’s specifications.
