How must compressed gas cylinders be stored?

OSHA addresses compressed gases in general at 1910.101; however, the standard does not provide detail with regard to storage of cylinders. Instead, 1910.101(b), refers employers to CGA Pamphlet P-1-1965 for in-plant handling of all compressed gases in cylinders.

With regard to cylinders, CGA P-1 says (among other things) that:

• Storage areas must be designed to accommodate the various gases with adequate spacing or segregation by partitioning so that containers can be grouped by hazard.
• Storage areas must be dry, well-drained, ventilated, and fire-resistant.
• Consideration should be given to separate storage of full and empty containers.
• Temperatures in the storage area must not exceed 125°F.
• There must be adequate separation from combustibles as specified by federal, state, and local regulations.
• There must always be a valve protection cap (if provided) in place.
• Containers may not be exposed to corrosive chemicals or fumes or stored near readily ignitable substances.
• Containers must be protected from cuts, punctures, or other abrasions of the metal.
• Containers must be secured with brackets, chains, or straps to prevent falling or damage.
• Containers must not be stored near walkways, elevators, stairs, unprotected platform edges, or where heavy objects may strike or fall on them.
• The method of storage must not expose the cylinders to tampering by unauthorized persons.
