Compressed Gas Cylinders

A full oxygen cylinder holds over 2,000 psi. If the valve breaks off, the cylinder can become a rocket. Fuel gas cylinders add fire and explosion risk.

• Construction
• General Industry

Storage

• Upright and secured with chains or straps so they can’t fall
• Valve protection caps on when not in use
• Oxygen stored at least 20 feet from fuel gas cylinders (like acetylene or propane), or separated by a noncombustible barrier at least 5 feet high with a half-hour fire rating
• Away from heat, sparks, electrical circuits, elevators, stairs and exits
• Labeled with contents; empty and full cylinders separated
• Well-ventilated area

Moving cylinders

• Use a cylinder cart with a chain, or a hand truck made for cylinders.
• Remove regulators and put caps on before moving (unless on a cart designed for use).
• Hoist cylinders only in a cradle or basket, never by the cap or with slings or magnets.

• Don’t roll cylinders on their sides or drag them.
• Don’t use cylinders as rollers or supports.
• Don’t use oil or grease on oxygen fittings. It can ignite.
• Don’t store cylinders in enclosed spaces or vehicle cabs.
