Chimney Fire: Causes, Warning Signs and Prevention

Chimney fires are caused by creosote igniting inside the flue. Warning signs include a loud cracking or popping, dense smoke, and an intense smell. Annual cleaning and burning seasoned wood are the best prevention.

What causes them

Creosote buildup is the fuel. Failure to clean heating equipment is the leading cause of home heating fires, which average about 48,530 a year [1].

Warning signs

A loud cracking or popping from the chimney, dense smoke, a strong intense smell, or a roaring sound. After any suspected chimney fire, stop using the fireplace and get a Level 2 inspection.

Prevention

Sweep annually before heating season, burn only seasoned wood, keep fires at a healthy temperature, and have the flue inspected each year.
