temperatures above 130°F will require
water spray cooling.
•Do not expose cylinders to electricity of any kind.
Do not use a cylinder or its contents for anything other than its intended use. Do not use as a support or roller.
•Do not locate cylinders in passageways
or work area where they may be struck.
•Do not use a wrench or hammer to open a cylinder valve that cannot be opened
•D_ not modify or exchange gas cylinder fittings.
•Do not deface or alter name, number or other markings on a cylinder. Do not rely
on cylinder color to identify the contents.
•Do not connect a regulator to a cylinder containing gas other than that for which the regulator was designed.
Do not attempt to make regulator repairs. Send faulty regulators to manufacturer's designated repair center for repair.
•Do not attempt to lubricate a regulator. Always change cylinders carefully to prevent leaks and damage to their walls, valves, or safety devices.
Always secure cylinders with a steel chain so that they cannot be knocked over.
•Always protect a cylinder, especially the valve, from bumps, falls, falling objects and weather. Remember that gasses in the cylinders are under pressure and damage to a regulator can cause the regulator or portion of the regulator to be explosively ejected from the cylinder. Always make certain the cylinder cap is securely in place on the cylinder, whenever the cylinder is moved.
Always close the cylinder valve and immediately remove a faulty regulator from service, for repair, if any of the following conditions exist.
•Gas leaks externally.
Delivery pressure continues to rise with down stream valve closed.
•The gauge pointer does not move off the stop pin when pressurized or fails to
return to the stop pin after pressure is released.
