However, storing them safely outdoors requires proper care and attention. Whether you’re a weekend griller or a business that relies on propane daily, understanding the best practices for outdoor propane tank storage is critical for both safety and efficiency.

This guide from our Devine Bros pros will provide practical tips, location considerations, and maintenance ideas for storing propane tanks correctly. By the time you’re finished reading, you’ll feel confident about keeping these necessary tools safe and functional.

Why Proper Storage of Propane Tanks Matters

Propane is an incredibly versatile and efficient fuel, but it also has its risks if not handled correctly. Improper storage can lead to leaks, tank damage, or even dangerous accidents. Here are just a few reasons why following proper propane storage guidelines is vital:

Safety: A leaking propane tank can pose risks of fire or explosion.
Compliance: Local regulations often dictate specific propane storage standards.
Prolonging Tank Life: Proper storage prevents rust, damage, and other wear.
Environmental Responsibility: Protecting tanks safeguards your surrounding environment from potential leaks.

Now, let’s explore the most effective ways to store a propane tank outside.

Outdoor Propane Tank Storage Tips

1. Choose the Right Location

Where you place your propane tank is one of the most critical factors when it comes to safe storage. Keep the following in mind:

No Enclosed Spaces: Never store a propane tank in a shed, garage, or basement. Propane tanks need proper ventilation to prevent gas buildup in case of a leak.
Distance from Structures: Place the tank at least 10 feet away from your home or any structure. This safety measure reduces risks in case of a leak or fire.
Avoid High-Traffic Areas: Use an area that’s out of reach from children, pets, and heavy foot traffic to prevent accidental bumps or damage to the tank.
Regulate Exposure to Direct Sunlight: While propane tanks are built to withstand varying weather conditions, placing them in a partially shaded area can prevent extreme heat from putting extra pressure on the tank.

2. Positioning the Tank Safely

Once you’ve found an appropriate location, ensure the tank is properly positioned. Follow these important steps:

Keep It Upright: Always store a propane tank upright. The pressure relief valve operates correctly only in this position, significantly reducing the risk of gas leaks.
Secure the Tank: If you’re in a windy area or have loose gravel, consider using cinder blocks or a tank stabilizer to keep the propane tank steady.
Elevate When Necessary: To prevent the tank’s bottom from rusting due to ground moisture, place it on a non-flammable platform, like a concrete slab.

3. Protect the Tank from Weather

Outdoor storage exposes propane tanks to the elements, so it’s crucial to protect them without enclosing them. Here are a few weather-related storage tips:

Snow and Ice: If you live in a snowy region, periodically brush snow off the tank with a soft cloth to prevent buildup. Avoid using sharp tools that could damage the surface.
Rain Exposure: Rust is propane’s greatest adversary. Use a propane tank cover or canopy to shield the tank from heavy rain.
Flood Zones: If you’re in a flood-prone area, store tanks in elevated locations. This not only protects from water damage but also prevents tanks from becoming dangerous floating debris during floods.

4. Check for Leaks Regularly

Routine maintenance is key to ensuring your propane tank remains safe. Check for leaks every time you refill, transport, or reconnect the tank. Here’s how:

Make a leak detection solution by mixing water with a small amount of dish soap.
Apply the solution around the tank valve and regulator using a spray bottle or brush.
If you see bubbles forming, there’s a leak. Discontinue use and get the tank inspected immediately.

Regularly inspecting the tank through this simple method helps prevent accidents before they happen.

5. Follow Local Regulations

Local guidelines or ordinances may dictate how and where propane tanks are stored. For example, some states specify a minimum distance between propane tanks and certain outdoor structures. Familiarize yourself with these rules to avoid penalties and ensure you’re practicing the safest storage techniques.

If you’re unsure about local requirements, contact propane suppliers or local authorities to clarify and confirm best practices.

6. Thorough Maintenance for Long-Term Storage

If you’re storing a propane tank that won’t be used for an extended period, additional maintenance steps are needed:

Remove Attachable Hoses or Accessories: Disconnect all hoses and equipment to prevent wear over time.
Close the Valve Tightly: Ensure the valve is completely shut before storing the propane tank.
Inspect Tank Before Use: Before reconnecting, check for signs of rust, warping, or other damage.

What NOT to Do When Storing a Propane Tank

By understanding what not to do, you can avoid common mistakes that compromise safety:

Don’t Store Indoors: Tanks need ventilation. Never keep a propane tank inside your home or enclosed spaces.
Don’t Smoke Nearby: Propane is highly flammable. Even a single spark can pose a serious risk.
Avoid Modified Covers: Never cover a propane tank with a flammable material such as cloth or plastic sheeting.
