Where Fuel Should Never Go, at a Glance

A good container isn't enough if it's sitting in the wrong spot. This guide covers the clear list of places fuel should never go, why vapor travels farther than you'd think, and the safe detached-shed or garage-corner alternatives in plain English. There's a printable 29-page version up top.

Common Questions

1 Where should I never store gasoline or propane?

Never inside the house, a basement, or any living space, and never near a water heater, furnace, stove, or any pilot light. Propane also never belongs in an attached garage.

2 Why does location matter so much for fuel?

Gasoline vapor and propane are both heavier than air and can travel along the floor to a spark or flame well across the room, even if the container itself is capped.

3 Can I store fuel near my generator while it's running?

No. A running or still-hot generator is its own heat and ignition source. Store fuel in its own spot, separate from the generator, and refuel only once it is off and cool.

4 Is it safe to leave a gas can in a hot car?

Not for long. Heat inside a closed vehicle builds pressure in the container and speeds up fuel breakdown. A quick errand is fine; long-term storage is not.

5 What's a genuinely safe spot for stored fuel?

A detached, ventilated shed, or the far corner of a garage well clear of ignition sources, out of the sun, off the traffic path, and away from kids and pets.

6 Does this apply to diesel too?

Yes — the same never-store list applies to diesel as much as gasoline. Our diesel storage and winter gelling guide covers diesel's own additional cold-weather habits.
