Garage Fire Hazard Checklist

Garages are the number one fire hazard area in most homes. Fuel, chemicals, cars, electrical tools, overloaded outlets, and forgotten appliances all live in the same cramped space. This checklist focuses on the hazards that actually start garage fires—and how to fix them before they do.

1. Flammable Liquids and Chemicals

[ ] Store gasoline, oil, paint thinners, and solvents in approved metal or plastic containers.
[ ] Keep all flammables away from heaters, pilot lights, and open flames.
[ ] Seal lids tightly to prevent vapor buildup.
[ ] Dispose of old paint, rags, and chemicals—don’t let them pile up.

2. Appliances and Heat Sources

[ ] Keep water heaters, furnaces, and dryers clear of clutter.
[ ] Ensure gas appliances have proper ventilation.
[ ] Clean dryer vents regularly to prevent lint ignition.
[ ] Avoid using space heaters in garages unless they are rated safe for the environment.

3. Electrical Safety

[ ] Don’t overload power strips or extension cords.
[ ] Inspect outlets and wiring for scorch marks or frayed cords.
[ ] Replace damaged power tools immediately.
[ ] Avoid running extension cords under rugs, mats, or heavy objects.

4. Tools and Equipment

[ ] Unplug power tools after use.
[ ] Store oily or solvent-soaked rags in metal containers with tight lids—these can self-ignite.
[ ] Keep cordless tool batteries away from direct heat sources.
[ ] Charge lithium tool batteries on non-flammable surfaces.

5. Vehicles and Fuel Systems

[ ] Check vehicles for fuel leaks, oil drips, or electrical issues.
[ ] Don’t leave vehicles running inside the garage—CO buildup is deadly.
[ ] Keep spare fuel containers sealed and upright.
[ ] Avoid storing large amounts of fuel unless it’s necessary and stored properly.

6. Storage and Organization

[ ] Keep combustibles (cardboard, paper, clothing) away from appliances and heaters.
[ ] Organize shelves so heavy items don’t fall and block exits.
[ ] Maintain clear walking paths through the garage.
[ ] Avoid storing items directly on the floor where they can absorb moisture or ignition sources.

7. Fire Protection and Detection

[ ] Install a fire-rated door between the garage and the house.
[ ] Ensure the door self-closes and seals properly.
[ ] Keep a multipurpose fire extinguisher mounted and visible.
[ ] Install heat detectors (not smoke alarms) rated for garage environments.

8. Ventilation and Airflow

[ ] Keep the garage well-ventilated when using chemicals or power tools.
[ ] Avoid operating fuel-powered tools inside a closed garage.
[ ] Use fans to clear fumes or dust when working on projects.
[ ] Ensure exhaust from cars or generators doesn’t flow back into the home.

9. Seasonal and Annual Checks

[ ] Check for rodent nests that can chew wiring or insulation.
[ ] Inspect weatherstripping on the garage door.
[ ] Tighten loose shelves or hooks that could collapse onto appliances.
[ ] Include garage inspections in your Home Safety Annual Review.

Garages are convenient, but they mix heat, fuel, electricity, and clutter in one place—basically everything a fire needs. Run this checklist twice a year or anytime your garage starts turning into a storage war zone.
