What You’ll Learn
How do I keep my propane tank safe when the summer heat gets extreme?
You should store your propane tank in a cool, shaded, and well-ventilated area—never in direct sunlight or near heat sources like grills or fire pits.
Always keep the tank in an upright position so the pressure relief valve can function properly, and regularly inspect the exterior for rust, dents, or a “rotten egg” smell that indicates a leak.

Summers can get mighty warm.
Sometimes it feels like you’re melting like a popsicle as soon as you step out of your door.
Imagine how your metal propane tank feels.
Summers can bring extreme heat, and while you’re trying to stay cool, it’s important to remember that your propane tank is feeling the heat too.
High temperatures can pose safety risks if propane tanks aren’t stored correctly.
Propane is a safe, eco-friendly energy source (43% more eco-friendly than using electricity from the grid), but like any fuel, it needs to be handled with care—especially when temperatures rise.
This guide will help you understand how to store your propane tank safely during the hot summer months, ensuring both your home and family remain protected.
What Is Propane?
Propane is a gas that’s often used in homes and businesses for heating and cooking. It’s also an ideal way to fuel vehicles and other equipment.
Propane is a byproduct of natural gas and petroleum stored as a liquid in pressurized tanks. As a fuel source, propane is a popular choice because it burns clean and efficiently.
When burned, it produces fewer emissions than other fossil fuels. This makes it more environmentally friendly for homeowners.
Propane is also relatively inexpensive, which makes it an attractive choice for many consumers.
However, propane is also highly combustible, which means it can be dangerous if not stored or used properly—particularly in hot weather.
That’s why understanding proper propane tank storage is critical, especially during the summer when temperatures can climb.
How High Temperatures Affect Propane Tanks
Though propane is versatile with its many uses, there are still some dangers to consider.
Propane tanks are designed to withstand a significant amount of pressure.
However, extreme heat can cause the propane inside the tank to expand, increasing the internal pressure.
If the pressure becomes too high, the tank’s pressure relief valve will open to release gas, which can lead to dangerous situations, including potential fires or explosions if there’s an ignition source nearby.
That’s why proper storage is essential.
Here are key tips to ensure your propane tank stays safe, even in high temperatures:
Propane Tank Safety Tips for High Temperatures
1. Store Propane Tanks in a Cool, Shaded Area
Keep propane tanks out of direct sunlight whenever possible. Prolonged exposure to the sun increases the internal pressure inside the tank.
If possible, store your tank in a shaded, well-ventilated area to keep it cool.
2. Keep Tanks Away from Heat Sources
Avoid placing propane tanks near grills, fire pits, or any other heat-generating appliances.
Even a small increase in external heat can cause the pressure inside the tank to rise, potentially triggering the pressure relief valve.
3. Store Tanks Upright
Always store your propane tank in an upright position to ensure the pressure relief valve functions correctly.
Storing tanks on their sides can prevent the valve from working properly and increase the risk of a dangerous situation.
4. Ensure Proper Ventilation
Storing your propane tank in a well-ventilated area is crucial, especially in high temperatures.
This helps to prevent pressure buildup inside the tank, keeping it stable and reducing the risk of leaks.
5. Regularly Inspect Your Tank
Routine inspection of your propane tank can help identify potential problems before they become dangerous.
Check for signs of wear, such as rust, dents, or leaks. If your tank shows any of these signs, it’s important to contact a professional for inspection or replacement.
Signs of Propane Tank Trouble
Identifying a malfunctioning propane tank is crucial for ensuring the safety of those around it.
Look for:
- Physical Damage: Dents, cracks, or rust can weaken the tank and lead to gas leaks. If you notice any damage, stop using the tank immediately and call a professional.
- Unusual Smells: While propane is naturally odorless, an odorant is added to help detect leaks. If you smell a strong odor around your tank, it could indicate a leak.
- Strange Noises: Hissing or whistling sounds from the tank or its connections can signal a pressure issue or gas leak. If you hear these sounds, shut off the tank and contact a professional immediately.
If you suspect that your propane tank is in trouble, it’s important to act immediately. This may include shutting off the valve to the tank. It could also mean evacuating the area or calling a professional for assistance.
Do your best to stay vigilant and watch for warning signs. In this way, you can help ensure the safety of yourself and those around you.
Emergency Preparedness for High Temperatures
Improper use of propane tanks in high temperatures can lead to serious hazards. These can include fire, explosion, and carbon monoxide poisoning.
Don’t underestimate the value of following the proper safety measures for both yourself and your family:
- Evacuate the Area: If you suspect a leak or hear strange noises coming from the tank, evacuate the area immediately.
- Shut Off the Tank: If it’s safe to do so, turn off the gas supply at the tank’s valve.
- Call for Help: Contact emergency services or a propane professional to report the issue and get assistance.
Proper Maintenance of Propane Tanks
Regular maintenance of propane tanks is crucial for many reasons. For one, doing so can help identify any potential issues or hazards before they become a problem. Proper maintenance can extend the life of the tank.
Be sure to follow the manufacturer’s guidelines for maintenance, though.
In addition, have the tank inspected and serviced by a qualified professional on a regular basis.
One important step in maintaining propane tanks is to keep them clean and free of debris. This can help prevent rust and other types of corrosion that can weaken the tank’s structure. Tanks should also be inspected for dents or cracks, which can compromise their safety.
Checking the tank’s valves, connections, and hoses for leaks or wear is also a good idea to do on a regular basis. Replace any damaged or worn components immediately.
Stay Safe This Summer with Proper Propane Tank Storage
Propane is an efficient and environmentally friendly fuel, but it requires proper care—especially during summer’s high temperatures. By following these safety tips and regularly inspecting your tank, you can ensure that your home remains powered safely and efficiently.

FAQs
Is it dangerous if my propane tank is sitting in the direct sun?
Yes, prolonged exposure to direct sunlight can cause the liquid propane inside to expand, increasing internal pressure.
If it gets too hot, the safety relief valve may open to vent gas, which creates a fire hazard if an ignition source is nearby.
Can I store my propane tank in the garage or a shed to keep it cool?
No, you should never store propane tanks indoors or in enclosed spaces like garages or sheds.
Proper ventilation is critical; if a small leak occurs in an enclosed area, the gas can pool and create an explosion risk. Keep them outdoors in a shaded, airy spot instead.
What should I do if I hear a hissing sound coming from my tank on a hot day?
A hissing sound usually means the pressure relief valve has opened to release excess pressure or there is a leak.
You should immediately shut off the tank valve if it is safe to do so, evacuate the area, and call a propane professional or emergency services to inspect the tank.
