The Risks of Creosote

One of the most memorable moments for many residents in the Western New York area is the warm and cozy ambiance of a wood-burning fireplace. However, for some homeowners, pleasant dreams can quickly turn into a nightmare when a chimney fire erupts in the middle of the night, filling their living space with dark, thick smoke. This unfortunate and completely preventable scenario occurs over 20,000 times a year, serving as a stark reminder of the significant risks associated with creosote.

The Dangers of Creosote

One of the dangers of creosote is that its accumulation is mostly hidden from view. Unlike a visible hazard, creosote builds up mainly inside the flue, often out of sight. Without an annual chimney inspection, it’s akin to playing a game of chance with potentially deadly consequences. Annual chimney inspections and professional sweeping are the only reliable way to identify and minimize this fire and health hazard. There are other risks too:

• Flue Obstruction: Significant creosote buildup can narrow the chimney flue, impeding the proper venting of smoke and hazardous gases, such as carbon monoxide. It can then cause these dangerous fumes to back up into your home, posing a serious health risk to occupants. Carbon monoxide is a colorless and odorless gas known as a “silent killer.”
• Health Hazard: Exposure to creosote can cause respiratory problems, eye and skin irritation, and is classified as a probable human carcinogen. Furthermore, the impaired venting due to creosote buildup can result in carbon monoxide poisoning, which is potentially fatal.
• Masonry Damage: The acidic nature of creosote can corrode the mortar joints and flue liners, weakening the chimney’s structural integrity. This damage can lead to cracks and loose or missing bricks, providing pathways for heat and flames to escape into combustible areas of your home.
• Foul Odors: Creosote can emit strong, unpleasant odors, especially on warm or humid days, making your home smell like a bad barbecue.

Types of Creosote

Another risk of creosote is that its flammability increases as it continues to build up inside the flue. Recognizing the different stages of creosote buildup can help in understanding the severity of the issue:

First-Degree Creosote:

Initially, creosote is typically a light, flaky, or powdery soot. It’s the least hazardous form and is relatively easy to remove with a standard chimney brush.

Second-Degree Creosote:

As it lingers, it gets harder, shinier, and often appears as black or brown flakes. It’s more difficult to remove than first-degree creosote and is typically the result of incomplete combustion.

Third-Degree Creosote:

The third degree is the most dangerous stage of creosote. It’s a hard, black, tar-like, or glazed material. In this stage, creosote is extremely challenging to remove, often requiring specialized tools and professional treatments. This highly flammable substance is now a significant fire risk, making an expert chimney cleaning essential for safety.

How to Prevent Creosote Buildup

While complete prevention of creosote is impossible due to the chemical nature of combustion, you can significantly minimize its accumulation and reduce fire risk by adopting these practices:

1. Burn Only Seasoned Wood: Use hardwoods that have been properly dried (“seasoned”) for at least six to twelve months. Seasoned wood has a moisture content of 20% or less, burns hotter and more completely, producing less smoke and creosote. Unseasoned (green) wood contains high moisture, resulting in cooler, smokier fires and increased creosote buildup.
2. Open the Damper: Always keep the damper open when burning a fire and wait until it burns out completely before closing the damper. Smoldering fires increase creosote buildup.
3. Avoid Overcrowding: Allow ample room for oxygen to circulate between the logs, allowing the fire to consume them more completely and resulting in less creosote.
4. Install a Fireplace Insert: A wood-burning insert is a closed-combustion system that fits inside an existing firebox. Inserts produce more heat with less smoke and minimal creosote.
