We use compressed gases for a variety of tasks at our facility. Yesterday we looked at storage of the cylinders . . . today we'll look at some tips for compressed gas handling and use.

Handling and Transporting

• Transport cylinders securely on a cart designed for cylinder use;
• Secure all cylinders during transport;
• Turn all cylinder valves off;
• Attach protective caps securely;
• Prohibit cylinders' use as rollers or supports for other equipment;
• Roll cylinders on their bottom edge when moving them short distances.

Using Compressed Gas

• Inspect all cylinders, valves, regulators, hoses, torches and other equipment prior to use;
• Position the cylinder valve end up when in use;
• Place cylinders away from burning and cutting operations;
• Vent the cylinder by slightly opening (cracking) valve prior to attaching a regulator or any hoses or piping. Avoid being in front of the valve opening when this is done;
• Use the proper regulator for the cylinder to reduce pressure;
• Ensure that all connectors are free of oil and grease;
• Ensure that fuel gas and oxygen hoses are easily distinguishable. All other lines are to be identifiable;
• Disconnect hose couplings with a rotary motion and a pull;
• Open all valves slowly;
• Use a friction lighter to ignite any flame;
• Upon completion, close all valves;
• Close cylinder valves tightly;
• Close needle valves ‘finger tight’ to avoid damage to valve and/or valve stem;
• Vent all hoses;
• Use a diffuser regulated to less than 30 psi to blow away dust, dirt and debris.
