Gasoline is a powerful and highly flammable fuel that millions of people use every day. It powers our cars, motorcycles, lawnmowers, and even some generators. While it is very useful, gasoline can also be dangerous if not stored properly. Knowing what you can use to store gasoline is important for safety, convenience, and compliance with the law.
In this article, we’ll explain what kind of containers you can use to store gasoline safely. We’ll also talk about where you should keep gasoline, how long it lasts, and what you can do to make it last longer. This guide is written in simple language so anyone can understand, even if you’re not a fuel expert.
Why Storing Gasoline Safely Is Important
Gasoline is not just another liquid. It’s highly flammable, which means it can catch fire easily. If you store it in the wrong kind of container, it can leak, evaporate, or even explode under the right conditions. This puts your home, vehicle, and life at risk.
Besides safety, there are legal rules about how and where gasoline should be stored. Failing to follow these rules can lead to fines or other penalties. That’s why it’s important to use approved containers and store them in safe locations.
What Type of Containers Can Be Used to Store Gasoline?
1. Approved Gas Cans
The most common and safest way to store gasoline is in containers that are specifically made for it. These are often called “gas cans” or “fuel cans.” But not just any plastic or metal can will do.
Look for gas cans that are:
- Approved by OSHA, DOT, or EPA – These agencies make sure the container meets safety standards.
- Clearly labeled for gasoline – The container should say “Gasoline” or have a fuel symbol.
- Made of the right materials – Strong plastic (HDPE) or metal that can resist fuel vapors and pressure.
You’ll often find these cans in red, which is the color code for gasoline.
Common sizes: 1 gallon, 2.5 gallons, and 5 gallons.
Pros:
- Easy to use and transport.
- Safe and legal.
- Made to prevent spills and evaporation.
Cons:
- Limited size.
- May swell in heat if not vented properly.
2. Metal Gasoline Containers
Metal gas cans are durable and long-lasting. They are often made of galvanized steel and have a tight-sealing cap to prevent leaks.
Brands like: Jerry Can, Eagle, Justrite.
Features:
- Stronger than plastic.
- Often come with flame arresters.
- Last for years with proper care.
Ideal for:
- Longer storage.
- Industrial use.
- Harsh environments.
Caution: Make sure they are rust-resistant and not dented. Dents can weaken the metal and cause leaks or pressure problems.
3. Gasoline Storage Drums
If you need to store larger amounts of fuel, like for a farm or generator, you can use a gasoline storage drum.
Size: Usually 30 or 55 gallons.
Made of: Steel or high-density polyethylene (HDPE).
Must include:
- A sealed lid.
- Vent cap or pressure relief valve.
- Labeling that says “Flammable.”
Used for:
- Long-term emergency fuel supply.
- Fueling vehicles or equipment on-site.
- Backup power systems.
Warning: Storing this much gasoline at home is not recommended unless you follow strict safety rules. Many local laws also limit how much fuel you can store.
4. Portable Fuel Tanks
Boaters, RV users, and off-road vehicle owners often use portable fuel tanks. These are made to store and transport gasoline in larger amounts.
Size range: 6 to 15 gallons or more.
Features:
- Built-in fuel gauge.
- Spout or pump hose.
- Designed for movement and refueling.
Note: These tanks should still be stored outside or in well-ventilated places when not in use.
5. Underground or Above-Ground Fuel Tanks
For businesses, farms, or large properties, professional fuel tanks are the best option. These are usually installed by certified technicians and follow state regulations.
Types:
- Underground Storage Tanks (USTs): Installed below ground level.
- Above-Ground Storage Tanks (ASTs): Rest on a concrete slab or metal stand.
Capacity: 100 gallons and up.
Requirements:
- Leak detection systems.
- Spill containment.
- Regular inspections.
These are not for the average homeowner, but they are ideal for people who need large amounts of gasoline regularly.
What You Should Never Use to Store Gasoline
It’s tempting to use any available container, but many are dangerous. Here’s what to avoid:
Milk Jugs or Water Bottles
These are made of thin plastic that can break down when in contact with gasoline. They also can’t handle pressure changes.
Glass Containers
Gasoline can break down glass over time and pressure buildup can cause it to shatter.
Food Containers
These can confuse someone into thinking the contents are safe to drink. That can lead to accidental poisoning, especially in homes with children.
Unlabeled Containers
Using a random container with no labels is dangerous. Emergency responders won’t know what’s inside, and you may forget too.
How to Store Gasoline Properly
Now that you know what to use, let’s talk about how and where to store gasoline safely.
1. Keep It in a Cool, Dry Place
Heat causes gasoline to expand and release vapors. These vapors can build up pressure inside the container and may lead to leaks or explosions.
Ideal places to store gasoline:
- Outdoor sheds
- Detached garages
- Fuel cabinets
Never store gasoline inside your house, basement, or near appliances like water heaters or furnaces.
2. Keep It Away from Flame or Sparks
Gasoline vapors are more flammable than the liquid itself. Keep containers far from:
- Fire pits
- Smoking areas
- Power tools
- Electrical outlets
Even a small spark can ignite gasoline vapors.
3. Use Ventilated Areas
If vapors build up in a closed space, they can become very dangerous. That’s why proper ventilation is key. Always store gasoline in a place where air can flow freely.
4. Store Upright and Securely
Place containers upright on a flat surface. Secure them so they can’t fall over. If you’re storing in a vehicle or trailer, use straps or brackets to keep them in place.
How Long Can You Store Gasoline?
Gasoline doesn’t last forever. Over time, it breaks down and becomes less effective.
Shelf life:
- 3 to 6 months without additives.
- Up to 12 months with fuel stabilizer.
After that, gasoline may become thick, lose power, and damage engines.
Tips to make it last longer:
- Use a fuel stabilizer like STA-BIL.
- Store in a tightly sealed, approved container.
- Keep it out of sunlight and heat.
Signs That Gasoline Has Gone Bad
- It smells sour or strange.
- It’s darker than usual.
- Your engine won’t start or runs poorly after using it.
If you suspect your gasoline is bad, don’t dump it on the ground or in a drain. Take it to a hazardous waste facility or a recycling center.
Legal Limits and Local Rules
Many places have laws about how much gasoline you can store at home.
Typical limits:
- 5 to 25 gallons at residential properties.
- Must be in approved containers.
- No gasoline inside living areas.
Check with your local fire department or city code office to know the rules in your area.
Extra Tips for Safe Gasoline Storage
- Label your containers clearly.
- Keep a fire extinguisher nearby.
- Don’t top off containers—leave some space for vapor expansion.
- Check for leaks often.
- Replace old or damaged containers.
Conclusion
Gasoline is a valuable resource, but it must be stored safely. The best way to store gasoline is in containers that are approved by safety agencies, made of strong materials, and designed for fuel. Whether you need a small red gas can or a large storage drum, there’s an option for every need.
Remember, safety always comes first. Store gasoline in cool, ventilated places away from flames, and never in your home. Use stabilizers if you plan to store fuel for a long time, and always follow local laws.
With the right knowledge and equipment, you can store gasoline safely and be prepared for whatever comes your way.
