Can a Gas Fireplace Explode? 

A gas fireplace cannot explode without a definite cause. There are just a few cases of gas fireplace explosions because of a faulty pilot light, user’s mistakes and most times bad equipment. To avoid sudden explosions, it is strongly suggested you make proper security evaluations and the fireplace itself is kept clean and well-maintained at all times.

Bear in mind that your gas fireplace can explode if you do not take proper care of it. An explosion is only possible if you refuse to follow the safety precautions. The pilot light of a gas fireplace must function well, and you need to ensure that you don’t leave your fireplace on when you are not using it. 

To avoid unintentional explosions, make sure the pilot light and the fireplace itself are kept clean and well-maintained. Also, your pilot light is out after use. A gas fireplace could explode when you turn it on if the pilot light is broken or if it has been left on while gas has accumulated. Make sure to regularly inspect your pilot light for signs of deterioration to avoid explosion. 

Carbon monoxide buildup in gas fireplaces is another reason a gas fireplace can explode. A dangerous buildup of carbon monoxide can occur in a fireplace, especially when there is improper ventilation and a pilot light has been left on.

Can a Wood Fireplace Explode? 

A wood fireplace is considered more prone to cause house fire because of the high heat. However, the chances of a wood fireplace exploding are slim. While it is possible for smoke to accumulate in a piece of wood that hasn’t dried out completely, a genuine fireplace explosion is unlikely. 

However, you can have a piece of wood that can cause fire sparks which is not dangerous unless a flammable object is close to it. Try to evaluate this piece of wood before use.
