The short answer
Keep gasoline only in an approved, tightly closed fuel container in a cool, ventilated detached structure away from flames, pilot lights, outlets, direct sun and floor drains. Set cans upright in a spill tray and buy only what you will use promptly. Never store gasoline in a house or basement; local fire code controls allowed quantities and locations.

A durable listed container with a flame arrestor and controlled-pour design.
Safe Storage Checklist
- Use a listed gasoline container, never a water jug or unapproved plastic can.
- Close the cap and vent exactly as the container maker directs.
- Keep cans upright in a stable spill tray where vehicles and tools cannot strike them.
- Separate fuel from chargers, switches, heaters, flames and anything that sparks.
- Keep the area locked from children and clearly labeled for adults.
| Location | Verdict | Main concern |
|---|---|---|
| Detached ventilated shed | Usually preferred | Heat and local quantity limits |
| Attached garage | Check local code | Ignition sources and shared air |
| Basement or living area | Never | Vapor and fire exposure |
| Direct sunlight outdoors | Never | Heat, pressure and container damage |
How Long Should You Keep Gas?
Gasoline changes during storage, especially ethanol blends. Date every can, rotate the oldest fuel first and follow the equipment and stabilizer instructions. Stabilizer slows degradation; it does not make fuel permanent or change fire-safety rules.
Frequently Asked Questions
- Should a gas can vent while stored?
- Use the container only as designed. Modern approved cans are generally kept closed; never improvise a vent that releases vapor.
- Can I store gasoline beside a lawn mower?
- Avoid crowding. Leave a stable, protected separation and keep both away from ignition sources.
- Is a metal safety cabinet required?
- Requirements vary by quantity and jurisdiction. A listed flammable-liquid cabinet adds protection but does not override local limits.
