What Causes Most House Fires in the United States?

Leaving food cooking on the stove is a top fire starter. Grease or oil can easily overheat and ignite. Distractions while cooking, like answering the phone, are a major risk factor. Always stay in the kitchen when you are frying, grilling, or broiling food. Keep anything that can catch fire, such as oven mitts and towels, away from the stovetop.

A common scenario involves forgetting a pan on a hot burner. The food dries out, chars, and eventually catches flame. Setting a timer can serve as a helpful reminder. If a small grease fire starts, carefully slide a lid over the pan and turn off the burner. Never use water on a grease fire, as it can cause a dangerous flare-up.

Electrical problems are a silent but significant fire threat. Old wiring in an aging home may not handle modern power demands. Signs of trouble include frequent circuit breaker trips, flickering lights, or a burning smell from an outlet. Have a qualified electrician evaluate your home's electrical system if you notice these warning signs.

Many electrical fires start behind walls, spreading unseen. Arc faults, where electricity jumps a gap, can ignite surrounding materials. Installing arc-fault circuit interrupters (AFCIs) in your electrical panel can help prevent these fires. Avoid running cords under rugs where damage can go unnoticed. Replace any cord that is cracked or has exposed wire.

• Frayed or damaged appliance cords.
• Overloaded power strips and outlets.
• Faulty or outdated wiring in walls.
• Light fixtures with bulbs exceeding the recommended wattage.
• Faulty switches or outlets that feel warm to the touch.
• Do-it-yourself electrical work done incorrectly.

Improper storage of flammable liquids is a major hazard. These vapors are heavier than air and can travel to an ignition source like a pilot light. Always store gasoline and solvents in approved containers outside your living area, like in a detached shed. Keep only small quantities for immediate needs and ensure the storage area is well-ventilated.

Barbecue grills cause numerous fires each year. For gas grills, check hoses for leaks at the start of the season. Position your grill well away from siding, deck railings, and overhanging branches. For charcoal grills, never add lighter fluid after the coals are lit. Let the coals cool completely before disposing of the ashes in a metal container.

• Gasoline and paint thinners stored indoors.
• Propane tanks for grills stored in garages or sheds.
• Charcoal lighter fluid used incorrectly.
• Gas grills operated too close to the house.
• Spontaneous combustion from oily rags.
• Flammable vapors accumulating in enclosed spaces.
