To store gas in a plastic gas can safely and effectively, it is crucial to use the correct container and adhere to specific filling guidelines. Gasoline must be stored in containers no larger than five gallons, and these containers should be filled no more than 95% full, with the cap kept tightly sealed to allow for thermal expansion.
Proper gasoline storage is vital for safety, preventing spills, and maintaining fuel quality. Following established guidelines ensures that potential hazards are minimized, especially when dealing with flammable liquids like gasoline.
Selecting the Right Container
The first step in safe gasoline storage is choosing an appropriate container. Not all plastic containers are suitable for fuel.
- Material: Gasoline should only be stored in containers specifically designed for fuel, which are typically made of plastic or metal. These are engineered to withstand the chemical properties of gasoline and prevent leaks.
- Size Limit: For safety and manageability, containers should be no larger than five gallons. Larger volumes increase the risk in case of a fire or spill and can be too heavy to handle safely.
- Certification: Always look for containers that meet safety standards, indicated by certifications like UL, FM, or ASTM. This ensures the can is built to safely contain fuel.
The Critical Filling Process
Once you have the correct container, the filling process requires strict adherence to specific rules to prevent dangerous situations.
Gasoline, like many liquids, expands and contracts with temperature changes. If a container is completely full, rising temperatures can cause the gasoline to expand, leading to increased pressure, potential bulging of the can, and even ruptures or spills.
| Aspect | Guideline | Reason |
|---|---|---|
| Fill Level | Fill the container no more than 95% full | Allows for thermal expansion of gasoline. |
| Cap Security | Keep the cap tight on the container | Prevents vapor escape and spills. |
It is paramount to keep the cap tight on the container after filling. A loose cap can allow hazardous gasoline vapors to escape, creating a flammable atmosphere, and can lead to spills if the can is tipped.
Post-Filling Storage Best Practices
After properly filling and sealing your plastic gas can, the location and ongoing maintenance are equally important for safe storage.
- Cool, Well-Ventilated Area: Store gasoline away from direct sunlight, heat sources (like furnaces, water heaters, or direct sun exposure), and ignition sources (e.g., pilot lights, electrical motors, or sparks). A detached shed or garage with good airflow is ideal.
- Stable Surface: Place the can on a stable, flat surface to prevent it from tipping over.
- Out of Reach: Always store gasoline cans out of the reach of children and pets.
- Regular Inspection: Periodically check the can for any signs of damage, cracks, or leaks, especially around the cap and spout. Replace damaged cans immediately.
- Labeling: Ensure the can is clearly labeled "Gasoline" to prevent accidental misuse.
By following these guidelines, you can safely store gasoline in plastic gas cans, minimizing risks and ensuring the fuel is ready when needed.
