The short answer

Cooking Fires Lead the List

Cooking is the leading cause of house fires across the country. Unattended stovetops, overheated oil, and food left in the oven can ignite quickly. Grease fires spread fast and are especially dangerous because water makes them worse. Always stay in the kitchen while frying, grilling, or broiling.

Keep flammable items like towels, paper towels, and wooden utensils away from the burners. Use a timer to remind you when food is cooking. If a small grease fire starts, slide a lid over the pan and turn off the heat. For larger fires, get everyone out and call 911 from outside.

  • Never leave cooking food unattended
  • Keep a lid nearby to smother small grease fires
  • Clean cooking surfaces to prevent buildup
  • Turn pot handles inward to avoid spills
  • Keep children and pets away from the stove

Heating Equipment and Fireplaces

Heating equipment, including space heaters, furnaces, and fireplaces, is the second leading cause of house fires. Space heaters cause a large share of these fires when placed too close to bedding, curtains, or furniture. The risk rises in colder months when homes use more heat. Keep anything that can burn at least three feet away from any heat source.

Have your furnace and chimney inspected regularly by a qualified professional. Never use an oven to heat your home. For fireplaces, use a sturdy screen to catch sparks and make sure ashes are cool before disposal. In colder regions, heating systems work harder during wet winters, so check them before the season starts.

  • Place space heaters on a flat, non-flammable surface
  • Turn off heaters when you leave the room or sleep
  • Use only the correct fuel for your heater
  • Clean the fireplace and chimney yearly
  • Install a carbon monoxide detector near sleeping areas

Electrical Fires and Wiring

Electrical fires rank third among common causes. They often start from faulty outlets, old wiring, or overloaded extension cords. When too many devices draw power from one outlet, the wiring can overheat and ignite nearby materials. Flickering lights, warm outlets, or frequent blown fuses are warning signs.

Avoid running extension cords under rugs or across doorways. Use power strips with built-in circuit breakers instead of daisy-chaining multiple cords. If you notice any electrical issues, hire a qualified electrician to inspect and fix them. Do not attempt DIY repairs on your home's wiring, as that increases fire risk.

Smoking and Candles

Smoking materials, like cigarettes and cigars, cause a significant number of house fires. These fires often start when a smoker falls asleep with a lit cigarette or when ashes land on upholstery or bedding. The fire can smolder for hours before bursting into flames. Never smoke indoors, especially in bed.

Candles also cause house fires, particularly in bedrooms. Always blow out candles before leaving a room or going to sleep. Use sturdy, non-flammable holders and keep them away from curtains and books. Consider flameless LED candles as a safer alternative for ambiance.

Children and Fire Safety

Children cause a small but real share of house fires, usually by playing with matches, lighters, or stoves. Curiosity about fire is natural, but it can lead to disaster. Keep all lighters and matches stored out of reach and in locked cabinets. Teach children that fire is a tool for adults, not a toy.

If you have kids, practice a home fire escape plan with two ways out of every room. Choose a meeting spot outside, like a tree or a neighbor's driveway. Make sure smoke alarms are installed on every level of your home and test them monthly. Working alarms give you precious seconds to get out safely.

Frequently asked questions

What is the most common time of day for house fires?

House fires most often happen in the evening, between 5 p.m. And 8 p.m., when families are cooking dinner. This aligns with the peak time for cooking-related fires. However, fires can occur at any hour, so stay vigilant throughout the day.

How can I reduce the risk of an electrical fire?

Avoid overloading outlets and use surge protectors for electronics. Replace frayed cords and never run them under rugs. Have a qualified electrician inspect your home's wiring every few years, especially if your home is older. Look for discolored outlets or a burning smell as warning signs.

What should I do if a fire starts in my kitchen?

For a small grease fire, turn off the heat and cover the pan with a metal lid. Never use water. For an oven fire, keep the door closed and turn off the oven. If the fire grows, leave the house immediately, close the door behind you, and call 911.
