Containers should be stored in a detached garage or shed, away from direct sunlight
Gasoline is a highly flammable and corrosive liquid with a flashpoint of -45ºF (-43ºC). It is capable of breaking down the chemical bonds in standard plastic containers, weakening the material and affecting the fuel's composition. This breakdown can cause the fuel to become unstable and unusable. Gasoline vapours are also highly flammable and can build up inside a container, creating a potentially dangerous situation. Therefore, it is crucial to follow safety guidelines when storing gasoline.
To ensure the safe storage of gasoline, it is recommended to keep the containers in a detached garage or shed. This separation from the main building provides an extra layer of safety in case of any accidental ignition. The storage area should be well-ventilated to prevent vapour buildup and kept at room temperature, away from direct sunlight, and any heat sources. Sunlight and heat can accelerate the evaporation process, leading to hazardous vapour leaks and an increased risk of ignition.
When storing gasoline in a detached garage or shed, it is essential to keep the containers out of the reach of children and pets. They should be placed in a secure location, such as leak-proof or flammable safety cabinets. Additionally, ensure that the storage area is free from any sources of ignition, including water heaters, furnaces, pilot lights, and power tools. By maintaining a safe distance from potential ignition sources, the risk of accidental fires is significantly reduced.
It is important to note that gasoline containers should always be stored upright and stabilized to prevent tipping. Proper ventilation of the storage area is crucial to mitigate the buildup of flammable vapours. Regularly inspect the containers for any signs of deterioration or wear and consider replacing them every five years to maintain optimal safety. Remember, when it comes to storing gasoline, prioritizing safety measures is of utmost importance.

Gasoline is a highly flammable and corrosive liquid with a flashpoint of -45ºF (-43ºC). It is not recommended to store gasoline in standard plastic containers, as it can react with the chemical composition of the plastic and break down its chemical bonds, weakening the material's strength and structure. This can also affect the fuel's chemical composition, causing it to become unstable and unusable. Gasoline vapours can build up in unvented containers, creating a potentially dangerous situation. Therefore, it is essential to use containers specifically manufactured for gasoline storage, such as Type I and Type II Safety Cans, which are made of specially formulated plastic or metal to withstand gasoline's corrosive effects.
When storing gasoline, it is recommended to keep the containers upright and away from direct sunlight and sources of ignition. The environment should be kept at room temperature, and the containers should be tightly sealed to prevent hazardous spills and vapour leaks. Heat, oxygen, and humidity impact the condition of stored fuel, with pure gas beginning to degrade and lose combustibility in three to six months due to oxidation and evaporation. Ethanol-gasoline blends have an even shorter shelf life of two to three months.
To maintain gasoline quality, it is best to use it within a month of purchase. Fuel stabilizers can be added to extend the shelf life, with gasoline lasting between one and three years under optimal conditions. However, it is recommended to replace gasoline every two years, even with stabilizers, as octane loss may occur after six months. Mixing old gasoline with fresh gasoline can also help, but it is not advisable to use gasoline over a year old, as it may damage internal engine components and cause blockages.
When storing gasoline in a vehicle, it should be stabilized and secured in the trunk, away from direct sunlight. For larger amounts of gasoline, it is recommended to store it in a separate building, such as a detached garage or shed, in leak-proof or flammable safety cabinets, out of the reach of children and pets.
