A large chimney fire has started in the chimney.

Owning a home with amenities is an amazing feeling. When purchasing a home, home buyers look for as many extra amenities in a home that is possible. In colder areas, you might have a strong desire to purchase a home with a fireplace. Additionally, in warmer areas, you might want a home with a swimming pool or enclosed patio. Either way, amenities are nice add-ons to a home. Keep in mind that having something extra like a fireplace will require added maintenance. You should really look to maintain your chimney on a regular basis. As you use the fireplace, creosote can build up in your chimney lining and create some unsafe conditions, such as a fire. Will a chimney fire burn itself out? No, you will likely need to put the fire out and call the fire department.

Let’s take a look below at what this all means.

How Does It Happen

Chimney fires can start with as simple of a reason as the chimney being too dirty. When you start a fire inside your fireplace, the burning logs and paper will give off a residue. As the smoke rises through your chimney, the residue can stick to the chimney’s flue. Over time, this creosote that has been created will build up. Because it is a sticky or tacky residue, the wood chips or embers that are floating through the air could stick to the residue.

When you start your next fire, this could ignite the creosote buildup in the chimney and begin to burn quickly. Unfortunately, when this occurs, the chimney gets very hot and starts to break down. The metal of the chimney’s flue begins to melt and now the extreme heat can gain access to other parts of your house. Essentially, igniting your roof or other wooded portions of the home.

Other items that could start a chimney fire include, nests created by birds, raccoons, squirrels, or other rodents. They will pack dirt and sticks and leaves into the chimney. When a fire is created in the fireplace, these items will burst into flames and start your chimney fire. Having a chimney cap will protect your chimney from this occurring.

Smoke coming from the chimney could be a clear sign of a potential chimney fire.

What Can I Do To Stop It

There are a few things you can do to put out a chimney fire. Let’s take a look.

  • Escape the flames – your main objective is to get everyone out of the house. Always be sure to have an evacuation plan for you and your family, in the event of a fire.
  • Call 911 – once everyone is safely out of the house, call 911. Emergency services can respond quickly and ensure that the fire is properly extinguished before it causes major damage to the home.
  • Turn off the fuel – if the fire isn’t major yet, you can work to remove the oxygen that is fueling the fire. Close the damper or flue openings to shut off the fire from any oxygen source. Additionally, grab your fire extinguisher and push short bursts into the fire source. Also, consider using sand, salt, or baking soda to put out the flames in your main firebox.
  • Spray it down – take your water hose from the outside of the house and begin spraying the chimney down. Make sure to use a gentle stream to ensure no damage is caused to the inside of the chimney.
  • Clean it out – remove all wood that was burned from your firebox or firepit in the fireplace. Use a metal bucket and scoop all of the debris from the fireplace so that it doesn’t keep fueling the fire.
  • Chimney extinguisher – use a product like a chimney extinguisher that is meant to suffocate a fire and safely put it out.
  • Trust Emergency Services – even if you believe that the fire has been extinguished, you will want the fire department to pay a visit and ensure that the fire is completely out. They can inspect the chimney and ensure that you will not have any further issues.
