Gas Cylinders
Compressed gas cylinders are to be shut-off at the bottle when not in use or unattended for short periods of
time. At the end of the shift the bottles are to be shut off and gauges and hoses detached, and properly stored
and protective caps installed.
Compressed gas cylinders shall have gauges removed and be capped prior to transportation. Cylinders shall
only be transported or stored in the up position.
Use approved storage racks or dollies to store compressed gas cylinders. Chain or #9 wire may also be used.
Never use rope for this purpose.
On welding rigs compressed gas cylinders shall be securely stored in vertical racks.
Oxygen and acetylene cylinders must be stored at a distance of 20 feet apart or be separated by a fire wall that
is 5 feet or higher and has a fire rating of 60 minutes or more. These cylinders must be kept at least 20 feet away
from combustibles or separated by a fire wall.
Do not use a choker or chokers to haul cylinders.
Keep cylinders away from work so sparks, slag, or flame cannot reach them. If cylinders cannot be isolated, fireresistant shields must be provided for them.
