Storing Gasoline At Home

In a preppers world where reliance on generators and radiators is common, especially in remote areas, the ability to store gasoline at home is a necessity.

Whether it’s for powering a generator, fueling a heater, or ensuring your vehicle and mower have enough gas, having a substantial reserve of gasoline can be a lifesaver.

However, when it comes to storing significant amounts,¬†it’s crucial to understand the best practices to ensure the gasoline doesn’t degrade and remains safe for use.

How Much Gasoline Can You Store at Home?

The amount of gasoline you can safely store at home largely depends on local regulations and the storage space available.

In the United States, the National Fire Protection Association (NFPA) and local fire codes typically allow residential storage of up to 25 gallons of gasoline. This gasoline should be stored in approved containers, each not exceeding 5 gallons in capacity.

It’s crucial to check with local fire departments or governmental agencies for specific regulations in your area, as these can vary. Additionally, the storage location plays a significant role in safety.

Choosing the Right Storage Containers

The cornerstone of safe gasoline storage is selecting the appropriate containers. Standard gas storage canisters are typically 5 gallons in size and are specifically designed to safely store fuel.

For those needing to store larger quantities, a larger fuel tank may be necessary. It’s imperative that the gasoline must be stored in containers to prevent the risk of ignition.

Optimal Storage Location

The location for gas storage is as crucial as the container choice. Storing gasoline in a garage or shed, ideally at least 50 feet away from any ignition sources such as pilot lights, space heaters, or furnaces, is recommended. Building a barrier to stop bullets around it could be a lifesaver! Gasoline vapor is heavier than air and can accumulate at ground level, so ensuring proper ventilation in the storage area is essential to prevent dangerous fume buildup.

Understanding Fuel Stabilizers

Over time, gasoline degrades due to oxidation and evaporation of volatile compounds, which can reduce its efficacy and harm engine components.

Fuel stabilizers play a crucial role in preserving quality allowing you to keep gasoline for longer. These additives slow down oxidation and maintain fuel volatility, extending gasoline’s shelf life significantly, often up to 12 to 24 months.

Stabilizers are particularly beneficial for gasoline stored in fluctuating temperatures or for long periods, as in emergency generators or seasonal equipment. It’s important to add stabilizers to fresh gasoline, as they cannot reverse the degradation in old fuel. The process involves pouring the stabilizer into the storage canister before adding gasoline, ensuring thorough mixing.

Safety Protocols

Safety should always be the top priority when storing large amounts of fuel. Store gasoline away from flammable materials, heaters, and direct sunlight. Gasoline vapors are highly flammable and can easily ignite if exposed to ignition sources. A well-ventilated storage area is crucial to prevent vaporization.

Transportation and Handling of Gasoline

Transporting gasoline from gas stations to your storage location requires caution. Use quality containers and secure them firmly in your vehicle to prevent spills. When transferring gasoline to storage containers, use a funnel to avoid spillage and do it in a well-ventilated area to avoid inhaling fumes.

Long-Term Storage Considerations

For long-term storage, regularly check the condition of the gasoline. If you notice a significant change in color or smell, it may be time to use the gasoline or dispose of it properly. Remember, gasoline is a petroleum product and should be treated with respect and caution.

Emergency Preparedness

In case of a spill or accidental exposure, have an emergency plan in place. Keep materials like sand or commercial absorbents handy to deal with spills, and ensure you have appropriate fire extinguishers nearby.

Educating Household Members

It’s important that all household members understand the risks associated with gasoline storage. Educate them on the proper handling procedures, the location of safety equipment, and the emergency plan in case of an accident.


Storing large amounts of gasoline at home, whether for a generator, heater, or mower, requires meticulous planning and strict adherence to safety protocols. By selecting the right storage containers, using fuel stabilizers, and following comprehensive safety guidelines, you can maintain a significant gasoline reserve without compromising its quality or your safety.

Balancing convenience with safety and legal compliance is key to successful home gasoline storage. Remember, proper storage and handling not only ensure the longevity of the gasoline but also safeguard the well-being of your household and environment.
