• Always keep the protective cap on the cylinder when not in use.
• Secure the cylinder in a proper storage area, or fasten the cylinder to a cart.
• Do not expose to excessive heat or direct sunlight.
• Do not drop, dent, or damage the cylinder.
• Use a pressure regulator and a safety pressure relief valve as part of the pressure testing equipment. The safety
pressure relief valve should be the non-adjustable, non-tampering type. The valve should bypass any time the
pressure exceeds its setting.
• Open the supply valve slowly. Use regulators and safety valves that are in good condition
