Can You Burn 20-Year-Old Pressure-Treated Wood?

For many years, pressure-treated wood was produced with a chemical called chromated copper arsenate (CCA). CCA is very effective at preventing rot and insect damage, but it contains arsenic, which is a known carcinogen. In 2003, the Environmental Protection Agency (EPA) banned the use of CCA in pressure-treated wood intended for residential use.
So if you have an old deck or fence made of pressure-treated wood that was built before 2003, it’s likely that it contains CCA. There are conflicting opinions about whether or not it’s safe to burn CCA-treated wood. The EPA says that “it is unlikely that burning pressure-treated wood would release harmful chemicals into the air,” but they also advise against using it for firewood or mulch.
The American Wood Preservers Institute takes a more definitive stance, saying that “burning any treated lumber is not recommended.” So what should you do if you have old pressure-treated wood on your property? If it’s in good condition and you’re not concerned about the potential health risks, you can continue to use it as long as you like.
But if you’re planning to replace it anyway, there’s no need to wait – go ahead and remove it now. And whatever you do, don’t burn it!
What Happens If You Burn Pressure-Treated Wood?
Burning pressure-treated wood can release toxins into the air, which can be harmful to your health. The chemicals in pressure-treated wood are designed to resist rotting and insect damage, but they can also be toxic. When burned, these chemicals can be released into the air and breathed in.
This can cause a variety of health problems, including respiratory irritation, headaches, and dizziness. If you must burn pressure-treated wood, do so in a well-ventilated area and wear a mask to protect your lungs from the toxins.

What Wood is Toxic to Burn in a Fire Pit?
There are a few types of wood that are considered toxic when burned in a fire pit. These include: treated lumber, painted lumber, plywood, and particle board. When these materials are burned, they can release harmful chemicals into the air.
In some cases, these chemicals can be dangerous to your health. If you’re using a wood-burning fire pit, it’s important to choose the right type of wood to burn. Some woods are more likely to produce harmful smoke and fumes than others.
Here are a few examples of woods that are considered toxic when burned: Treated lumber: Treated lumber is often used in construction projects because it’s resistant to rot and pests. However, the chemicals used to treat the wood can be released into the air when it’s burned.
These chemicals can be dangerous to your health if inhaled. Painted lumber: Painted lumber is also treated with chemicals that can be released into the air when burned. In addition, burning painted wood can release lead into the air, which can be dangerous if inhaled.
Plywood: Plywood is made up of layers of glued-together wood veneers. The glue that’s used to bind the layers together can contain formaldehyde, which is a carcinogen. When plywood is burned, formaldehyde can be released into the air along with other harmful chemicals.
Particle board: Particle board is made from sawdust or other small pieces of wood that are glued together and pressed into sheets. Like plywood, particle board contains formaldehyde glue, which can release harmful fumes when burned.
Is Smoke from Pressure-Treated Wood Toxic?
Yes, smoke from pressure-treated wood is toxic. The chemicals in the pressure-treated wood, including arsenic and chromium, can be released into the air when the wood is burned. These chemicals can cause serious health problems if inhaled, including cancer.

Can You Burn Pressure-Treated Lumber?
Yes, you can burn pressure-treated wood in a fire pit. However, you should take some precautions first. Make sure the pressure-treated wood is completely dry before you burn it.
Wet pressure-treated wood can release chemicals into the air that can be harmful to your health. Also, avoid burning pressure-treated wood indoors or in enclosed spaces. The chemicals released from the burning wood can build up and create a toxic environment.
