What is the ocean standard for gas cylinder storage outdoors?

While I don't have a specific "ocean standard" for outdoor gas cylinder storage, here's what the provided documents say about storing gas cylinders outdoors:

• General Requirements: Store cylinders in specifically assigned, well-ventilated locations, away from heat sources and damp environments 4, 19. The temperature should not exceed 125°F (52°C) [1]. Post signs prohibiting smoking and open flames within 20 feet [1].
• Protection: Protect cylinders from sparks, hot slag, or flames, and ensure they don't contact electrical welding equipment or circuits [1]. Protect them from corrosion, being knocked over, and damage from passing or falling objects 4, 10. Prevent tampering by unauthorized persons [1].
• Separation: Separate oxygen cylinders from fuel-gas cylinders or combustible materials (especially oil or grease) by a minimum distance of 20 feet or a noncombustible barrier at least 5 feet high with a fire-resistance rating of at least one-half hour 7, 14.
• Storage Practices: Store cylinders with valve caps in place and valve end up, secured from movement [2]. Close all individual oxygen and flammable gas cylinder valves on portable cylinder banks when in storage 11, 14.
• Handling: Provide adequate access for cylinder handling 11, 16. Remove regulators and ensure valve protection is in place before moving unsecured cylinders 11, 16. Use a special truck, cylinder hand truck, a cart, or cylinder pallet to move cylinders 11, 16.

It's also important to consult the Compressed Gas Association (CGA) Pamphlet P-1, "Safe Handling of Compressed Gases in Containers" for detailed guidance 3, 6, 16.
