What type of wood is suitable for room heating? Can You Burn Pressure Treated Wood? Let’s see.
There have been many room heating devices recently- thanks to technological advancement. Winters can be devastating if you have no source of heat for your home as it comes with extreme cold. Regardless, wood burning as a source of room heat has existed since time immemorial and still is not about to be abandoned.
Even as you light up your fireplaces to keep warm, you need to avoid exposing yourself to chemicals through wood burning. To stay safe from wood burning poisoning, we need to find answers to this question: Can you burn pressure treated wood?
DO NOT burn a pressure treated wood, whether the wood is old or new. Pressure-treated wood contains dissolved chemicals used during the wood’s treatment and, when inhaled, can cause different health complications like cancer.
The U.S. Environmental Protection Agency’ EPA prohibits the burning of pressure treated it and goes as far as considering these materials as hazardous wastes.
What Is Pressure Treated Wood?
Pressure treated wood is a name given to a wood that has gone through a special process to make it more lasting and less susceptible to rot, decay, insect attack, mold, and damage by water.
There are types of pressure treatment of wood that can make them fire retardant. Different types of wood pressure treatment are designated for different projects.
Some woods are pressure treated to be used with ground contact, while others are treated for above ground contact uses.
Alkaline Copper Quat, abbreviated as ACQ, is the most common preservative used in the pressure treatment of wood. This chemical is poisonous to insects and fungi that cause rotting.
It, therefore, makes the wood less vulnerable to damages caused by insects and rot, water, and or fire. Pressure treated woods are, however, not necessarily waterproof.
Dangers of Burning Pressure Treated Wood
Disposing of a pressure treated wood through burning comes with severe health and environmental hazards. This action is prohibited by 50 states of the United States of America. Here’s why you must not burn pressure Treated Wood.
- The other name for treated wood is CCA lumber. Where the abbreviation CCA stands for Copper, Chromium, and Arsenic. According to studies, a single 12ft x 2in x 6in board of treated wood has arsenic that can kill 250 grown-ups.
- Burning is, in fact, the fastest way of releasing these chemicals to the environment. One tablespoon of ash of a pressure treated wood is exceptionally lethal. Arsenic, for example, is a silent killer chemical that has no taste or smell that can warn you of its presence.
- In normal circumstances, pressure treated wood comes in a dark brown or an OD green color. Besides, it has half inch-long splits all over its surfaces. Those are the areas of injection of the treatment. Therefore if you are not sure about the wood, don’t burn it.
- A report by the Journal of the American Medical Association on a study about the effects of burning pressure treated wood, a family used a treated wood during the winter to warm the room. After a couple of months, members of that particular family reported that their hair started falling out, they experienced crippling headaches and suffered nosebleeds.
- In the report, the parents cited multiple instances where they blacked out for hours. The two children experienced seizures. The house plants withered and eventually died, the fish in the aquarium died as well. After examination, the symptoms linked to the small traces of ash dust that were in the house.
- It’s encouraged to burn construction waste woods if you are looking to dispose of them. All you need to do is to double-check and ensure that the wood you are burning is pure and not treated.
How to Dispose of Pressure Treated Lumber
Pressure treated wood is a renowned construction material for outdoor structures such as fences, furniture, porches, decks, picnic tables, flower beds, and even buildings. A plank of treated wood offers more resistance to molds, insects, and deterioration, unlike the untreated counterpart.

Uses of Pressure Treated Lumber
Usually, the pressure treated wood will have marks or tags showing what types of projects are bests for its use.
Additionally, the woods are graded depending on appearance. For instance, wood with fewer knots is graded higher and costs more.
Home Indoor & Outdoor Use
The pressure treated with water-based preservatives like CCA will make the best option in the home and residential areas for interior and exterior use.
The water-based chemicals in some treated wood make them best for wood decks, fences, docks, and related structures.
Heavy Duty Construction
For heavy construction projects, wood treated with creosote preservatives is the most preferred. These woods are used for the construction of bridges, guardrails, as well as docks.
It is also essential to know that oil-based preservatives are primarily used to treat lumber used in utility poles, cross arms, etc.
Another aspect you should note is the projected use of the treated wood. Will you use your wood for above ground or be in contact with the ground.
It would be great for above-ground projects if the wood is at least six inches from the ground. Besides, it’s essential to ensure that the wood has active ventilation and drainage.
When working with woods that will be making contact with the ground, you should use lumber designed to withstand the moisture that comes with the ground contact.
Wood treated for ground contact comes with twice the level of chemical retention plus protection compared to the above-ground treated wood.
Burning of pressure treated wood is and should never be an option when looking for ways to get rid of them. It begs the question, how do you dispose of pressure treated wood?
If your pressure treated wood is no longer beneficial to any of your projects, here are some of the actions you can take to help free up your space.
