DID YOU KNOW?
Creosote, the substance that causes most chimney fires, was once used medically as an anesthetic. [2] Today, it’s known primarily as a highly flammable byproduct of burning wood — and it’s lurking in chimneys across the country.
KNOW THE RISK
- Dirty chimneys are a leading cause of house fires in colder months. These fires can reach over 2,000°F and easily ignite nearby walls, ceilings, or roofing materials. [1]
- Chimneys expel combustion by-products such as smoke, unburned wood particles, and water vapor. As these gases cool inside the flue, they leave behind creosote. [1]
- Creosote is a tar-like, highly flammable substance that builds up over time — especially when burning unseasoned wood or using inefficient stoves. [1]
MITIGATE THE RISK
1. Burn Only Seasoned Wood
- Use dry, seasoned hardwoods to reduce creosote buildup. Green or wet wood burns inefficiently and produces more smoke and residue. [1]
2. Schedule an Annual Chimney Inspection
- Have your chimney inspected and cleaned by a certified professional once a year, especially before heating season. [1]
3. Don’t Overload the Fireplace
- Burn smaller, hotter fires that produce less smoke. Avoid overloading your fireplace or wood stove with too much wood. [1]
CHIMNEY FIRE SAFETY REMINDER
Fireplaces add comfort and charm — but they come with risks. Routine cleaning and safe burning practices are essential to prevent chimney fires that can spread through your home in seconds.
