There are a few things that you should never burn in your fireplace, as doing so could create health hazards or start a fire. The following items should never be burned in a fireplace:
1. Plastic: Burning plastic releases harmful chemicals into the air and can also cause soot build-up on your fireplace.
2. Styrofoam: Like plastic, burning styrofoam can release harmful chemicals into the home. In addition, it can melt and stick to the inside of your chimney, which could create a fire hazard.
3. Paper products: While you may be tempted to burn paper products in your fireplace to create ambiance, it's actually quite dangerous. Burning paper creates embers that can easily escape the fireplace and ignite nearby objects.
4. Green wood: Green wood contains moisture which causes it to produce more smoke than dry wood when burned. The excess smoke could damage your fireplace or even start a house fire.
