How to Safely Store Gasoline? A Comprehensive Guide

Safely storing gasoline requires strict adherence to regulations and best practices to mitigate the risk of fire, explosion, and environmental contamination. Understanding proper container selection, storage location, and disposal methods is crucial for both personal and community safety.

Understanding the Hazards of Gasoline Storage

Gasoline, while essential for many aspects of modern life, is a highly flammable and volatile liquid. Its vapor, not the liquid itself, is what ignites, and these vapors can travel considerable distances to an ignition source. Improper storage significantly increases the risk of:

Fire and Explosion: Escaping gasoline vapors can be easily ignited by sparks, open flames, or even static electricity.
Health Hazards: Inhaling gasoline vapors can cause dizziness, nausea, headaches, and long-term health problems. Skin contact can cause irritation.
Environmental Contamination: Leaking gasoline can contaminate soil and groundwater, leading to significant environmental damage and costly cleanup efforts.

Choosing the Right Container

Selecting the appropriate container is the first, and arguably most crucial, step in safe gasoline storage.

Approved Gasoline Containers

Only use approved gasoline containers that meet or exceed safety standards set by organizations like the Underwriters Laboratories (UL) or the American Society for Testing and Materials (ASTM). These containers are typically made of:

High-density polyethylene (HDPE): This plastic is durable, resistant to gasoline, and designed to vent pressure. Look for containers clearly labeled for gasoline use.
Metal: Metal gasoline cans are also acceptable, particularly those made of UL-listed steel. They should be in good condition, free from rust, dents, and leaks.

Never use containers that were not specifically designed for gasoline storage, such as milk jugs, glass bottles, or unapproved plastic containers. These are not equipped to handle the pressure buildup and can degrade, leading to leaks and potential hazards. Pay close attention to the color coding of the cans. Red cans are generally the standard for gasoline, however, specific jurisdictions can have different regulations so do check with your local fire department.

Container Size and Labeling

Choose a container size that suits your needs. Smaller containers are easier to handle and reduce the potential for large spills.

Always label the container clearly with the word “GASOLINE” in large, legible letters. This helps prevent accidental misuse or confusion. Include the date the gasoline was purchased.

Safe Storage Location

The location where you store gasoline is just as important as the container itself.

Outdoor Storage

Store gasoline containers outdoors in a well-ventilated area, away from direct sunlight and sources of heat or ignition.
Keep containers at least 50 feet away from any buildings or structures.
Store on a level surface to prevent tipping.
Consider using a dedicated storage shed constructed of non-combustible materials like metal, that is specifically designed for flammable liquids, to provide an additional layer of protection. The shed should also have ample ventilation.

Indoor Storage (Limited Quantities)

Indoor gasoline storage should be avoided whenever possible. However, if necessary, limit the quantity to a maximum of 25 gallons (check local regulations, which may be stricter).
Store gasoline in a detached garage or shed, not in the living area of your home.
The storage area must be well-ventilated and away from furnaces, water heaters, electrical panels, and other potential ignition sources.
Store containers on the ground, away from stairs or exits.

Best Practices for Handling Gasoline

Handling gasoline requires caution to minimize spills, vapor release, and the risk of static electricity buildup.

Filling Containers

Fill gasoline containers outdoors in a well-ventilated area.
Place the container on the ground to prevent static electricity buildup.
Avoid overfilling the container; leave some space for expansion due to temperature changes.
Use a funnel to minimize spills.

Transporting Gasoline

Ensure the container is tightly sealed before transporting it.
Place the container in a stable position in the vehicle, preventing it from tipping or sliding.
Do not transport gasoline in the passenger compartment of a vehicle.
Avoid leaving gasoline containers in a hot car for extended periods.

Disposing of Old Gasoline

Old gasoline can degrade and become less effective. It can also damage engine components.
Never pour gasoline down the drain or into the environment.
Take old gasoline to a household hazardous waste collection center or a designated recycling facility.
Some auto repair shops may also accept used gasoline.

Frequently Asked Questions (FAQs) About Gasoline Storage

FAQ 1: How long can I safely store gasoline?

Gasoline typically has a shelf life of 3 to 6 months when stored properly. After this time, it can start to degrade, losing its octane rating and forming gums and varnishes that can damage engine components. Adding a fuel stabilizer can extend its shelf life to up to 12 months or even longer.

FAQ 2: What is a fuel stabilizer, and how does it work?

A fuel stabilizer is a chemical additive that helps prevent gasoline from degrading over time. It works by inhibiting oxidation and the formation of gums and varnishes. Add fuel stabilizer to gasoline when you purchase it, following the instructions on the product label.

FAQ 3: Can I store gasoline in my basement?

Absolutely not. Basements are poorly ventilated, and gasoline vapors can accumulate, creating a serious fire and explosion hazard. Furthermore, basements often have sources of ignition such as furnaces or water heaters.

FAQ 4: What should I do if I spill gasoline?

Immediately stop the spill if it is safe to do so. Use absorbent materials like sand, cat litter, or paper towels to soak up the gasoline. Dispose of the contaminated materials properly at a hazardous waste collection center. Ventilate the area thoroughly. Do not use water to clean up a gasoline spill, as it will spread the gasoline.

FAQ 5: Is it safe to store gasoline near propane tanks?

No. Gasoline and propane are both flammable and should be stored separately, away from each other. Maintain a minimum distance of at least 50 feet between gasoline and propane storage areas.

FAQ 6: Can I store gasoline in a plastic container that held other chemicals?

No. Even if the container is thoroughly cleaned, residual chemicals can react with the gasoline, creating hazardous conditions. Always use a container specifically designed for gasoline.

FAQ 7: What are the signs that gasoline has gone bad?

Signs of bad gasoline include a darker color, a sour or varnish-like odor, and a thick, gummy texture. If you suspect gasoline has gone bad, do not use it in your vehicle or equipment.

FAQ 8: Do I need a special permit to store gasoline?

In many jurisdictions, yes, especially for larger quantities. Check with your local fire department or environmental agency to determine the regulations in your area. Restrictions may vary depending on the amount of gasoline being stored.

FAQ 9: How often should I inspect my gasoline containers?

Inspect gasoline containers regularly, at least once a month, for signs of damage, leaks, or rust. Replace any damaged containers immediately.

FAQ 10: What type of fire extinguisher should I have on hand when handling gasoline?

You should have a Class B fire extinguisher readily available. Class B extinguishers are designed for flammable liquid fires.

FAQ 11: Is it safe to store gasoline in a shed attached to my house?

It’s generally not recommended. While better than storing inside the house, an attached shed still poses a risk. Ensure the shed is well-ventilated, and separated from the house with a fire-resistant barrier (like a firewall). Check local building codes for specific requirements.

FAQ 12: What are the long-term effects of gasoline exposure?

Chronic exposure to gasoline vapors can lead to neurological problems, respiratory issues, and skin irritation. Long-term exposure has also been linked to certain types of cancer. Always handle gasoline in a well-ventilated area and wear appropriate protective gear, such as gloves and a respirator.

Conclusion

Safe gasoline storage is paramount for protecting your health, property, and the environment. By following these guidelines and adhering to local regulations, you can minimize the risks associated with gasoline and ensure its safe and responsible use. Remember, prioritizing safety is always the best policy when dealing with flammable liquids.
