Can You Close Fireplace Glass Doors with Embers? A Comprehensive Guide to Fireplace Safety

Closing your fireplace glass doors with embers inside is a question many homeowners grapple with. The short answer is: generally no, not immediately. While seemingly convenient, doing so can create a dangerous situation and potentially damage your fireplace. This comprehensive guide will explore the risks, best practices, and alternative solutions to ensure both your safety and the longevity of your fireplace.

The Dangers of Closing Fireplace Doors on Embers

Several significant risks are associated with closing fireplace glass doors while embers are still glowing:

1. Risk of Suffocation and Smoke Backdraft:

The most immediate danger is suffocation. If you close the doors too soon, the embers will continue to smolder, consuming available oxygen within the fireplace. This can lead to incomplete combustion, generating dangerous levels of carbon monoxide and other harmful gases. These gases can then backdraft into your home, posing a serious health risk. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and vomiting. If you experience these, get fresh air immediately and call emergency services.

2. Increased Fire Risk:

Closing the doors traps heat and reduces airflow. This can cause the embers to reignite more intensely, potentially leading to a flashover—a sudden, rapid spread of fire. The confined space within the fireplace can amplify the heat, making it much harder to control any resulting fire.

3. Damage to Your Fireplace:

The intense heat trapped within the fireplace can cause damage to the glass doors, seals, and even the firebox itself. Cracking or shattering of the glass is a common consequence, requiring expensive repairs or replacements.

4. Creosote Buildup:

Incomplete combustion due to restricted airflow increases creosote buildup in your chimney. Creosote is a highly flammable substance, significantly increasing the risk of a chimney fire. Regular chimney cleaning is crucial for preventing chimney fires, but closing the doors on embers exacerbates the issue.

When is it Safe to Close Fireplace Glass Doors?

You should only close your fireplace glass doors when:

• All embers have completely cooled. This means no visible glowing embers and minimal heat radiating from the ashes. You should be able to comfortably touch the ashes with your hand (use caution, still!).
• There is no visible smoke. Any smoke indicates incomplete combustion and ongoing burning.
• The air around the fireplace is cool to the touch. If the surrounding areas are still warm, the embers are still releasing heat.

Safer Alternatives to Closing the Doors Immediately

Instead of closing the doors directly on embers, consider these safer alternatives:

• Allow for ample ventilation: Keep the fireplace doors open until the embers are completely extinguished. A good airflow will help them cool down quicker.
• Use a fireplace screen: A sturdy fireplace screen provides a layer of protection while still allowing for ventilation.
• Add more fuel (carefully): If the fire is dying down too slowly, adding a small amount of dry kindling can help complete the combustion process, leading to quicker cooling. However, always exercise caution and never add fuel when the fire is too intense.
• Use a fireplace poker and ashes: Gently stir the ashes to help the embers cool down more evenly. This aids in faster extinguishment.

Maintaining Fireplace Safety: Best Practices

• Regular chimney cleaning: Schedule annual inspections and cleanings to remove creosote buildup and prevent chimney fires.
• Proper ventilation: Ensure adequate ventilation in the room to prevent the buildup of smoke and harmful gases.
• Use a chimney cap: A chimney cap prevents rain and debris from entering the chimney, potentially causing issues.
• Never leave a fire unattended.
• Keep flammable materials away from the fireplace.

By understanding the risks and following these safety precautions, you can enjoy the warmth and ambiance of your fireplace without compromising your safety or the integrity of your fireplace. Remember, patience and caution are key to preventing accidents. If you are unsure about any aspect of fireplace safety, consult a professional chimney sweep or fireplace installer.
