Is it safe to store gasoline in an attached garage on wooden shelves during hot summer months around kids and pets?

Short answer

⚠️Depends / use caution

It depends; storing gasoline in an attached residential garage with wooden shelves can be risky, especially in high summer temperatures and when children or pets are present.

Why people ask this

Families with small children and pets often wonder if it’s safe to store gasoline in their attached garage, especially during summer when temperatures can reach 90°F. Concerns focus on vapor buildup, fire or explosion risk, and accidental exposure if gas cans are within reach.

When it might be safe

There are no commonly accepted situations where this is considered safe.

When it is not safe

Keeping gas cans on open, easily accessible wooden shelves where kids or pets could reach them
Storing gasoline in an attached garage with poor ventilation, especially if the window stays closed
Allowing containers to be exposed to direct sunlight or placed near heat sources
Using non-approved or damaged gas cans that may leak
Continuing to store gasoline indoors if any strong gasoline odor is noticeable or if anyone in the home feels lightheaded or dizzy

Possible risks

Accumulation of gasoline vapors, which are highly flammable and explosive, especially in enclosed hot spaces
Children or pets accidentally knocking over or opening containers, leading to poisoning or fire risk
Gasoline cans degrading over time, increasing the likelihood of leaks
Wooden shelves soaking up small spills, adding to fire risk
Possible health symptoms from vapor inhalation, including headaches, nausea, or respiratory issues

Safer alternatives

Store gasoline in a detached, well-ventilated shed or outbuilding if possible
Use only approved, tightly sealed gasoline containers designed for home storage
Keep gasoline off shelves and locked in a child- and pet-proof cabinet away from direct heat
Limit the amount of gasoline stored at home to the smallest amount necessary
Consider using electric lawn equipment to reduce the need for gasoline storage

Bottom line

Storing gasoline in an attached garage with limited ventilation—especially on accessible shelves during hot months—is not the safest option for families with kids or pets. Use approved containers, keep gasoline locked away and out of reach, and consider storing it outside the home if possible.
