Compressed gases are stored in heavy walled metal cylinders designed and tested for use with these gases. The cylinders come in a wide range of shapes and sizes.
Cylinders should be inspected upon delivery to your facility. Inspect each cylinder for:
Damage, corrosion, pitting, dents, or gouges.
Odors, visible fumes, or hissing sounds which indicate leaks.
Presence of a visible label and other identifying markings. Never rely on the cylinder’s color to identify the gas. Suppliers may use different colors for the same gas.
Protective valve caps. Always leave the valve cap in place until the cylinder is used. Make sure to look through the ports in the cap to identify rusted, dirty, or damaged valves and fixtures. Do not accept delivery of the cylinder, if it does not pass inspection.
Regular inspections of cylinders and cylinder storage areas can ensure the safe storage and use of compressed gas cylinders. When conducting routine storage inspections:
Examine regulators, pressure relieve valves, and cylinder connections.
Ensure cylinders are free of corrosion, leaking, pitting, dents, or gouges.
Ensure that gas cylinders are stored in a cool, dry, well-ventilated area, away from incompatible and combustible materials and ignition sources. Storage areas should not exceed 125 degrees Fahrenheit (52 degrees C).
Ensure that oxidizing agents are stored 20 feet (6 meters) away from fuel gases or other combustible materials or separated by an approved firewall.
