How to Store Refrigerant Cylinders Safely

Refrigerant cylinders should be stored in a cool, dry, well-ventilated place, kept upright, and secured so they cannot fall. They should be kept away from heat, flame, and direct sun. Good storage protects people, keeps the product safe, and helps you stay within the rules.

Keep cylinders cool

Refrigerant is stored under pressure, and heat raises that pressure. Store cylinders away from heaters, direct sunlight, and hot equipment. As a general rule, cylinders should not be kept in areas hotter than about 125 degrees Fahrenheit. Check the cylinder label for the maker’s limit.

Choose a dry, ventilated space

A dry area helps prevent rust on the cylinder and valve. Good airflow is important too. If a leak ever happened, ventilation helps keep refrigerant from building up in the air.

The basics of safe storage are easy to remember: cool, dry, upright, secured, and away from heat. Following them protects your team and your product.

Store cylinders upright and secured

Cylinders should stand upright whenever possible. They should be secured with a chain, strap, or rack so they cannot tip or roll. A falling cylinder can be heavy enough to cause injury or damage the valve.

Protect the valves

Keep valve caps in place when cylinders are not in use. The valve is the most delicate part of the cylinder, and a damaged valve can be dangerous. Keep cylinders away from anything that could strike or corrode them.

Keep storage organized and secure

Keep cylinders clearly labeled so the type of refrigerant is easy to see. Separate full cylinders from empty ones. Store them where only authorized, trained people can reach them, and away from chemicals that could cause corrosion.
