Is Your Garage a Fire Risk? Michigan Home Safety Tips

Organized Michigan garage with labeled shelves, a workbench, and a red fire extinguisher mounted on the wall, illustrating safe storage and fire prevention.Your garage pulls double duty: parking, storage, projects, and occasionally a quick entry into your home. That mix can raise your garage fire risk, but a few simple steps will dramatically improve home fire prevention in Michigan. Use the guide and checklist below to declutter, fix wiring hazards, and handle lithium batteries safely.

Quick Win: Spend 15 minutes this week to clear flammables from the floor, mount a fire extinguisher by the door, and set a safe charging spot for tools and e-bikes.

Why Garages Are Especially Vulnerable

Garages combine vehicles, power tools, paints, fuels, cleaning chemicals, and cardboard storage, often near ignition sources. Add old wiring, power strips, and space heaters, and you’ve got conditions that can let a small issue become a big problem fast.

Smart Storage: Reduce Fuel for Fire

  • Declutter first: Recycle or relocate excess cardboard, newspapers, and old fabrics.
  • Contain flammables: Store gasoline, solvents, and finishes in approved containers inside a fire-rated cabinet (or a detached shed when practical).
  • Raise it up: Keep items off the floor and away from water heaters, furnaces, and space heaters.
  • Clear exits: Maintain a 36″ path to doors and the electrical panel.

Wiring & Electrical Hazards

Electrical issues are a leading cause of garage fires. Treat your garage like a workshop and wire it accordingly.

  • No “permanent” extension cords: Add outlets instead of daisy-chaining power strips.
  • One big appliance per outlet: Freezers, air compressors, and heaters should not share a strip.
  • Inspect cords: Replace any that are loose, brittle, warm to the touch, or visibly damaged.
  • Upgrade old wiring: If lights flicker or breakers trip, schedule a licensed electrician.
  • Use a heat alarm: In garages, a heat detector can be more reliable than a smoke alarm due to exhaust and dust.

Lithium-Ion Batteries: Charge & Store Safely

Tools, e-bikes, scooters, and yard equipment often use lithium-ion batteries. They’re efficient, but when damaged, overheated, or charged improperly, they can ignite rapidly.

  • Designate a charging zone: a clear, nonflammable surface; never on cardboard or near solvents.
  • Monitor charging: Don’t charge overnight or when no one is home. Unplug when full.
  • Check condition: Swollen, punctured, or water-damaged packs should be recycled—do not use.
  • Cool, dry storage: Keep spares away from direct sun, heaters, and car exhaust.
  • Use OEM chargers: Stick with manufacturer-approved chargers and cables.

Minimum Safety Gear for a Michigan Garage

  • Wall-mounted ABC fire extinguisher: Install by the interior door for a quick, safe exit path. See the recommended extinguisher.
  • Fire-rated storage cabinet: Lock up fuels, paints, and solvents. See cabinet options.
  • Self-closing, fire-rated door between house and garage, with intact weather-stripping.
  • Spill control: Use trays or absorbent pads under vehicles that leak fluids.
  • Lighting: Bright, consistent lighting reduces mistakes with tools and fuels.

Garage Fire-Prevention Checklist (Printable)

  • ☐ Clear 36″ paths to all doors and the electrical panel.
  • ☐ Remove excess cardboard, paper, and fabrics from floor and corners.
  • ☐ Store gasoline, paints, and solvents in approved containers inside a fire-rated cabinet.
  • ☐ Eliminate permanent use of extension cords/power strips; add outlets if needed.
  • ☐ Inspect/replace damaged cords; label breakers; test GFCI outlets.
  • ☐ Set a monitored lithium-ion charging zone on a nonflammable surface (no overnight charging).
  • ☐ Mount an ABC extinguisher near the interior door and note the inspection date.
  • ☐ Verify self-closing, fire-rated door to the house; fix gaps/seals.
  • ☐ Place spill trays/absorbent pads under vehicles or small engines that drip.
  • ☐ Schedule an annual garage safety walk-through; add the date to your calendar.
