Follow these guidelines for the safe and proper handling, storage and use of compressed gas cylinders:
Gas cylinders may contain up to 3,000 psi pressure. Serious accidents have occurred when the valve stems of these cylinders were broken off.
Cylinders should be regularly checked for corrosion, cracks, general distortion, or any other defect that may indicate a weakness or render them unfit for service. The bottom of the cylinder should also be inspected.
All cylinders should be legibly marked to clearly identify the type of gas.
All valves should be closed off before a cylinder is moved, when the cylinder is empty and at the completion of each job.
Valve caps must be in place on all cylinders with a water weight capacity over 30 pounds when not in use.
Storage of empty or full compressed gas cylinders shall involve the securing of every cylinder by an approved chain or webbing to prevent a tipping, falling or rolling hazard. Empty and full cylinders should be stored in separate areas or be separated by a fire wall.
Cylinder tags that designate status (full, in service, empty) shall be used.
Those cylinders in use shall be properly secured in an upright position and shall be transported only on cylinder carts. A cylinder valve should be opened slowly to avoid valve damage.
Compressed gas cylinders should be stored in areas protected from external heat sources such as flame impingement, intense radiant heat, electrical arc or high temperature lines.
Cylinders should be located or stored in areas where they will not be damaged by passing or falling objects or subject to tampering by unauthorized persons.
