Gasoline breaks down plastic, causing leaks and potential explosions
Gasoline is a highly flammable and corrosive substance, and it needs to be stored in carefully designed containers to prevent spills, leaks, and accidents. Gasoline slowly vaporises and can build up pressure in a sealed container, so gas cans typically have vents to prevent this. Gas containers are also designed to prevent tipping and to withstand abuse.
Storing gasoline in a plastic container can be dangerous because gasoline can break down plastic. Gasoline reacts with the chemical composition of standard plastics, breaking down the chemical bonds that hold the plastic's polymers together, which gives the plastic its structure and strength. This can cause leaks, and the breakdown can also affect the fuel's chemical composition, causing it to become unstable and potentially unusable.
Some plastics are more susceptible to gasoline than others. Gasoline can dissolve certain plastics, while others are not affected. It is important to use containers that are specifically designed for storing gasoline, as they are made of materials that can withstand gasoline's corrosive effects without deteriorating. These containers are rigorously tested and approved for safety.
It is worth noting that gasoline vapours are also flammable, and any container holding gasoline must be properly vented to prevent vapour buildup, which can lead to a potentially dangerous situation. It is recommended to follow local fire codes and regulations for safe storage. Additionally, gasoline should be kept away from potential heat sources and ignition sources, such as lit cigarettes, pilot lights, and power tools.

Some plastics are more resistant to gasoline than others
While ordinary plastic containers are not suitable for storing gasoline, some plastics are more resistant to gasoline than others. Gasoline is a highly corrosive and flammable liquid, and when stored in standard plastic containers, it can react with the chemical composition of the plastic and break down its chemical bonds. This breakdown can also affect the fuel's chemical composition and cause it to become unstable and potentially unusable.
Some plastics, such as HDPE (High-Density Polyethylene), are denser and more resistant to gasoline. HDPE drums can hold gasoline for a longer period of time compared to regular plastic containers. These HDPE containers are also designed to be dent and corrosion-resistant, which helps them last longer. Additionally, Type I and Type II safety cans are specifically designed for storing smaller amounts of gasoline. These containers are made of specially formulated plastic and metal that can withstand the corrosive effects of gasoline without deteriorating.
It is important to note that even with these specialized containers, there are limitations to how long they can safely store gasoline. For example, HDPE drums will eventually start reacting with gasoline, causing them to break or become brittle over time. Therefore, it is recommended to replace plastic gas cans every five years or sooner if there are signs of deterioration or wear and tear.
To ensure safety, it is crucial to follow guidelines and use approved containers for storing gasoline. Metal containers, while less convenient due to their weight and mobility, offer a safer and longer-term solution for gasoline storage. However, plastic containers that are specifically designed and approved for gasoline storage, such as those made of HDPE or polypropylene, can also be a safe option for shorter periods.

Plastic gas containers must be replaced regularly
The plastic used in standard containers is not designed to withstand the corrosive effects of gasoline over extended periods. The polymers that make up the plastic will eventually react with the gasoline, causing the container to break or become brittle. This process is accelerated by extreme temperatures, particularly heat. As such, it is recommended to replace plastic gas containers every five years or earlier if there are signs of deterioration or wear and tear.
The safe storage of gasoline in plastic containers also depends on the type of plastic used. High-Density Polyethylene (HDPE) is a type of plastic that can be used to store gasoline safely for a longer duration. HDPE is denser and more resistant to the corrosive effects of gasoline. However, even HDPE containers will eventually break down due to the chemical reaction with gasoline.
To ensure safety, it is essential to follow guidelines and use approved containers. Type I and Type II safety cans are specifically designed for storing gasoline and are made of specially formulated plastic and metal. These containers are rigorously tested and certified by organizations such as OSHA, FM, and UL. They are also designed to reduce the risk of flammable liquid vapor explosions and are marked with a distinctive red colour for easy identification.
In summary, plastic gas containers must be replaced regularly to mitigate the risks associated with gasoline storage. Users should be vigilant in inspecting their containers for any signs of deterioration and adhere to recommended replacement intervals. By doing so, they can help ensure their safety and prevent potential hazards.
