The Risks of Storing Gasoline in Plastic Containers

When it comes to storing gasoline, many individuals and households opt for plastic containers, believing them to be a safer alternative to metal containers. However, it's crucial to understand the potential risks associated with using plastic for gasoline storage. This article explores the factors that make plastic storage containers risky and provides guidance on how to mitigate these risks effectively.

Understanding the Safety Risks

While some plastic containers are specifically designed to hold gasoline without degradation, others can pose significant risks. The primary concerns include chemical breakdown, vapor release, and physical deformation due to prolonged exposure to gasoline.

Chemical Breakdown of Plastics

Not all plastics are created equal when it comes to gasoline resistance. Polyethylene, a common type of plastic, is often used in gasoline storage containers because it can withstand gasoline well. However, many other plastics can break down over time, leading to the release of harmful chemicals and compromise the safety of the container.

The author mentions a personal experience of using a plastic milk jug to store gasoline as a young person, which resulted in a melted container and a hazardous spill. This incident highlights the importance of using containers that are specifically designed for gasoline.

Physical Hazards and Fumes

Gasoline storage in plastic containers can also increase the risk of vapor release and physical deformation. The author notes that while some plastic containers may last for years, they can eventually become brittle and crack, especially when exposed to prolonged sunlight.

The case study provided by the author demonstrates how gasoline stored for an extended period (from 2018 to 2021) can lose its ability to ignite due to degradation of the fumes. This experience underscores the importance of regularly checking and maintaining the condition of gasoline stored in plastic containers.

Preferred Containers: Jerry Cans vs. Plastic Jugs

The author recommends using Jerry Cans for larger storage quantities of gasoline. Jerry Cans are DOT (Department of Transportation) approved, meaning they are designed to withstand the rigors of transportation and storage. These containers are often preferred over plastic gallon jugs for their structural integrity and safety.

When compared to plastic jugs, Jerry Cans do not expand or collapse due to the gasoline pressure. Additionally, Jerry Cans are specifically designed for fuel storage and come with built-in safety features such as venting systems that prevent overpressure.

Best Practices for Storing Gasoline

To minimize the risks associated with storing gasoline in plastic containers, consider the following best practices:

Avoid Direct Sunlight: Store gasoline in a cool, dark place to prevent the plastic container from overheating and breaking down. Choose Appropriate Containers: Use containers that are specifically designed for gasoline, such as DOT-approved Jerry Cans or fuel cells made of polyethylene. Routinely Check and Maintain Containers: Inspect your containers regularly for any signs of damage or degradation, especially when storing gasoline for an extended period.

By following these guidelines, you can significantly reduce the risks associated with storing gasoline in plastic containers, ensuring both safety and efficiency in your fuel storage practices.

Conclusion

The use of plastic containers for gasoline storage presents several risks, including chemical breakdown, vapor release, and physical deformation. By understanding these risks and adopting appropriate storage practices, individuals can ensure the safe and reliable storage of gasoline, thereby reducing potential hazards and ensuring the integrity of their fuel supply.
