SET-UP AND SAFE OPERATING PROCEDURES
0056-0114
Keep oil and grease away from cylinders.•
Cylinders should be screened against direct rays from the sun.•
Protect cylinder valves from bumps and falling objects.•
Inspect the cylinder valves for damaged parts. Keep the valves clean, free from oil, grease, •
and all foreign materials.
Close cylinder valves when not in use, when empty, or when moving cylinders.•
Always be sure the cylinder valve is tightly closed before removing the regulators.•
Always replace the cylinder valve cap, if applicable, when the cylinder is not in use.•
Never allow anyone to strike an arc or tap an electrode against any cylinder.•
Never try to fill a cylinder or mix gases in a cylinder. Never draw gas from cylinders except •
through properly attached pressure regulators or equipment designed for the purpose. If
damaged, send the regulator to the supplier or qualified repair technician for repairs. Do not
tamper with or alter cylinder numbers or markings.
Never use cylinders as supports or rollers.•
When transporting cylinders with a crane, use an approved cylinder cradle only. Never use a •
“magnet” crane to move cylinders
Never lift the cylinder by its protective cap.•
If you are unable to make a gas-tight seal between the cylinder valve and a regulator nipple, •
check to see if the connection nut is tight. If so, check the regulator inlet connection for
damage. If the cylinder valve is damaged, remove the cylinder from service and notify the
gas supplier.
Never insert washers of lead or other material between the regulator and cylinder valve. Never •
use oil or grease on the connections.
NEVER• use compressed gas cylinders without a pressure reducing regulator attached to the
cylinder valve.
Never drag cylinders or roll them on the bottom edge, use a suitable cylinder cart.•
Never transport gas cylinders inside a passenger vehicle. Only transport gas cylinders in •
a suitable ventilated service vehicle. See CGA PS-7, “CGA Position statement on the Safe
Transportation of Cylinders in Passenger Vehicles”.
Use only standard cylinder keys to open cylinder valves, never extend the length of these •
keys under any circumstances. If valves cannot be opened by hand, do not use a hammer or
a wrench; notify the supplier.
Leave the cylinder key in position when fuel gas cylinder valves are open.•
Some cylinder valves, most notably acetylene cylinder valves, may require adjustment of the •
valve packing. Consult your gas supplier for the proper method of adjusting the packing. DO
NOT use the cylinder if the packing is leaking.
