Proper Storage Of A Propane Cylinder: 6 Tips

Written on: June 21, 2021

If you have a propane grill or propane patio heater, chances are you power it from a 20-pound propane cylinder. Since propane is a flammable gas, it needs to be stored safely outdoors; by using the proper storage techniques, you can keep your cylinder working well for years to come.

Here are six things to keep in mind if you want to store your propane cylinder safely.

1. Don’t leave your tank in an enclosed space. If a propane gas leaks indoors, it could make the area dangerous to be near, let alone in. The spark of a light switch could be enough to cause a terrible accident. Always store propane tanks outside. Mark the area where your tanks are with flags during snow season so you can easily find them in the event of accumulation. Consider storing them with a waterproof cover, or inside a tank box certified for that purpose, to minimize rust and tank damage.
2. Store the tank upright on a flat surface. Always store a tank upright, since the over-pressure vent must be in contact with the propane vapor, not the liquid, to work effectively. Make sure that the area is flat so the tank doesn’t tip over or roll away.
3. Avoid temperature extremes. Keep your tank above −40 °F (−40 °C) in cold months. As the temperature drops, the pressure in your tank will decrease. During cold months, make sure the propane tank is in a sunlit area so that it can absorb radiant heat every day. During summer, avoid exposing your tank to temperatures above 120 °F (49 °C). As the temperature rises, the pressure inside your tank rises, too. Never leave your tank in the sunlight during the hottest months! Look for a shady spot instead.
4. Keep your tank away from flammable materials. This includes open flames or any appliance that generates heat, including space heaters. Keep it away from your grill, too – if a fire breaks out, you’ll have two problems on your hands.
5. Keep your tank away from the vents and windows. Propane gas is heavier than air, so it will sink closer to the ground and may go into vents or basement windows. In the event of a leak, you don’t want to place tanks in an area where propane gas can enter you home. Never store your propane tank near air conditioners or heat vents, which could draw the gas into your home. If propane leaks into your home, evacuate the area immediately and call your local officials.
6. Attach your tank to your grill for an easy storage option. Turn the valve off (on top of your tank), and turn all grill valves to the “off” positions. Use a grill cover to protect it from the elements and direct sunlight. This makes it easier for you to use the grill at any time of the year.
