Compressed Gas Cylinder Safety

Introduction
Compressed gas cylinders can be extremely hazardous when misused or abused. Compressed gas cylinders can present a variety of hazards due to their pressure and/or content.
Depending on the particular gas, there is a potential for simultaneous exposure to both mechanical and chemical hazards. Gases used maybe:
Flammable or combustible
Corrosive
Explosive
Poisonous
Inert
Acidic
Reactive
or a combination of hazards.
Handling and Use
1. Before cylinders are first used the following precautions should be taken:
Make sure the cylinder is equipped with the correct regulator.
Inspect the regulator and cylinder valves for grease, oil, dirt, and solvent. Never use grease or oil to lubricate regulators or cylinder valves because they can cause an explosion.
The cylinder should be placed so that the valve handle at the top is easily accessible.
When using toxic or irritating gas, the valve should only be opened while the cylinder is in a working fume hood.
Only use wrenches or tools that are provided by the cylinder supplier to open or close a valve.
Fire extinguishing equipment should be readily available when combustible materials can be exposed to welding or cutting operations using compressed cylinder gases.
2. Cylinder Storage
Gas cylinders must be secured at all times to prevent tipping.
Use appropriate material, such as chain, plastic coated wire cable, commercial straps, etc., to secure cylinders.
Gas cylinders can not be stored in public hallways or other unprotected areas.
Cylinders must be segregated in hazard classes while in storage. Oxidizers (oxygen) must be separated from flammable gases, and empty cylinders must be isolated from filled cylinders.
The proper storage for oxygen cylinders requires that a minimum of 20 feet is maintained between flammable gas cylinders and oxygen cylinders or the storage area be separated, at a minimum, by a firewall five (5) feet high with a fire rating of 30 minutes.
Store out of direct sunlight and away from sources of heat and ignition; temperatures must not exceed 125 F.
Acetylene cylinders must never be stored on their sides.
Always place valve protectors on gas cylinders when the cylinders are not connected for use.
Cylinders must be protected from damage. Do not store cylinders near elevators or gangways, or in locations where heavy-moving objects may strike or fall on them.
Cylinders should be protected against tampering by unauthorized individuals.
Storage areas must be well-ventilated, cool, dry, and free from corrosive materials.
3. Moving Cylinders
Never drag, slide or roll a cylinder; use a cylinder cart or basket.
Always have the protective cap covering the valve when transporting the cylinder.
Never transport the cylinder with the regulator in place.
Make sure the cylinder is secured to the cart before moving it.
Do not drop cylinders or strike them against each other or against other surfaces violently.
Do not use the valve cover to lift cylinders; they could be damaged and become unattached. If the cylinder is dropped on a hard surface it can cause an explosion.
4. Use and Operation
Only properly trained personal should handle compressed gas cylinders.
Back off the pressure adjusting screw of the regulator to release spring force before opening the cylinder valve.
Open the valve slowly and only with the proper regulator in place. Stand with the cylinder between yourself and the regulator (cylinder valve outlet facing away) when opening the cylinder valve.
Acetylene or other flammable gas cylinder valves should not be opened more than 1⁄2 turns of the spindle, and preferably no more than 3⁄4 of a turn. This reduces the risk of explosion and allows for the cylinder valve to be closed quickly cutting off the gas flow.
Never heat a cylinder to raise the pressure of the gas (this can defeat the safety mechanisms built in by the supplier).
Keep the cylinder clear of all-electrical circuits, flame, and sparks.
Do not refill a cylinder; mixing of residual gases in a confined area may cause a dangerous reaction.
5. Cylinder Leaks
If the cylinder contains a flammable, inert, or oxidizing gas, remove it to an isolated area, away from possible ignition sources. Allow it to remain isolated until the gas has discharged, making certain that appropriate warnings have been posted.
If the gas is a corrosive, remove cylinder to an isolated, well-ventilated area. The stream of leaking gas should be directed into an appropriate neutralizing material.
For toxic material, the cylinder should be removed to an isolated, well-ventilated area, but only if this is possible while maintaining personal safety.
