Compressed Gas Cylinder Safety

Compressed gas cylinders pose mechanical, physical, inhalation, and/or other health hazards if used carelessly.  Here are some tips for working with compressed gas cylinders.

  • Secure them to wall or vertical support by means of restraining straps or chains
  • When moving cylinders, use a cylinder cart with a chain restraint in place
  • Valve protection caps should be installed on cylinders at all times when not in use
  • Cylinders should never be dropped, rolled, or carried in a horizontal position
  • Cylinders should never be used as rollers for moving equipment
  • If a cylinder or cylinder valve is leaking, call EHS
  • NEVER stick anything into the cylinder cap holes in an attempt to loosen the cap
  • Use an adjustable strap wrench to remove stuck caps
  • If the cap is still difficult to remove, attach a tag or label to the cylinder identifying the problem and return the cylinder to the supplier
  • Wrenches should not be used on valves equipped with a handwheel. If the valve is difficult to operate or faulty, contact your supplier

In addition, liquid nitrogen cylinders that release their contents can purge an area of oxygen. Never enter a room if a liquid nitrogen cylinder releases its contents and do not ride on an elevator that is transporting a liquid nitrogen cylinder
