Wet wood damages a fireplace

Burning high moisture-content wood in your fireplace produces more smoke than seasoned wood. This, in turn, can cause dangerous creosote to build up on the walls of your chimney. Burn only dry wood. Be sure you always check your chimney before using your fireplace.

Some plants

Painted or treated wood

Because burning painted and treated wood can release dangerous, toxic chemicals into your home, keep them out of your fireplace. Not only can these chemicals irritate lungs, eyes, and skin, but they can damage the inside of your fireplace.

Christmas trees

It seems logical that you could get rid of your old Christmas tree in the fireplace, but it’s best to dispose of it by other means. Not only is the wood not properly seasoned, evergreen trees often contain high levels of quick-burning resin which can reach high temperatures and result in a chimney fire or even crack your chimney.

It doesn’t matter what type of plastic you have—plastic bags, bubble wrap, plastic bottles, or cartons—never throw it in the fireplace. When burned, plastic releases harmful chemicals that can be dangerous for your health. Or, try to reduce your plastic consumption entirely.

Some papers and cardboard

It may be tempting to toss old papers, wrapping paper, or that cardboard pizza box in the fireplace, but you should dispose of paper and cardboard with colored print another way. The brightly colored inks may release toxic gasses when burned.

The synthetic fibers in dryer lint can release dangerous chemical fumes into your home and chimney. Choose a healthier way to ignite your fire. See what should never end up in your dryer, including excess dryer lint.

Fire accelerants

Never use fire accelerants such as gasoline, grill starter fluid, or kerosene to start a fire. These highly flammable liquids can cause a fire that quickly becomes too hot for your fireplace and chimney, putting the integrity of your chimney and your home at risk. It’s best to keep these accelerants out of your home. Next, check out these little things that could be making your home a fire hazard.
