Burning Old Pressure Treated Wood: A Chainsaw Pro’s Perspective

As someone who’s spent a significant portion of my life around chainsaws, wood, and open fires, I’ve learned a thing or two about the respect they command. The smell of freshly cut oak on a crisp autumn day, the satisfying crackle of a well-built fire – these are some of life’s simple pleasures. But there are boundaries we must never cross, and burning pressure-treated wood is one of them.

The Allure of the Flames and the Hidden Dangers

I understand the temptation. You’ve got some old deck planks lying around, they’re taking up space, and a bonfire seems like an easy solution. “Why not?” you might ask. “It’s just wood, right?” Wrong. Pressure-treated wood isn’t just wood. It’s wood that has been chemically altered to resist rot, insects, and fungal decay. And those chemicals? They’re not something you want going up in smoke.

A Personal Anecdote: A Lesson Learned the Hard Way

Years ago, before I truly understood the dangers, I made a mistake. I was helping a friend clear out an old shed, and we decided to burn some old lumber, including some pressure-treated pieces. The fire burned hot and fierce, and we thought nothing of it. But later that day, both of us started feeling sick – headaches, nausea, and a general feeling of being unwell. It wasn’t until days later, after researching the effects of burning treated wood, that we realized our error.

Understanding Pressure-Treated Wood

To understand the risks of burning pressure-treated wood, we first need to understand what it is and how it’s made.

What is Pressure-Treated Wood?

Pressure-treated wood is lumber that has been impregnated with chemical preservatives under high pressure. This process forces the chemicals deep into the wood fibers, making it resistant to decay and insect infestation. It’s commonly used in outdoor applications like decks, fences, and landscaping timbers.

The Evolution of Wood Preservatives

The types of chemicals used in pressure treatment have evolved over the years. Older pressure-treated wood often contained chromated copper arsenate (CCA), which, as the name suggests, contains arsenic. CCA was phased out for residential use in 2003 due to health concerns, but it’s still used in some industrial applications.

Newer pressure-treated wood typically uses alkaline copper quaternary (ACQ) or copper azole (CA). While these are considered less toxic than CCA, they still contain copper and other chemicals that can be harmful if inhaled or ingested.

Identifying Pressure-Treated Wood

How can you tell if wood is pressure-treated? Look for these clues:

Color: Pressure-treated wood often has a greenish or brownish tint, though this can fade over time.
Stamps or Labels: Look for stamps or labels that indicate the wood has been pressure-treated and specify the type of preservative used. These stamps usually include information like “ACQ,” “CA,” or the older “CCA” marking.
End Tags: Many pieces of pressure-treated lumber have end tags stapled to them, providing information about the treatment process and intended use.
Age: If the wood is older than 2003, it’s more likely to contain CCA.

The Dangers of Burning Pressure-Treated Wood

Now, let’s get to the heart of the matter: why you should never, ever burn pressure-treated wood.

Toxic Fumes and Gases

When pressure-treated wood burns, the chemicals it contains are released into the air as toxic fumes and gases. These fumes can contain:

Arsenic: A known carcinogen that can cause various health problems, including lung cancer, skin cancer, and bladder cancer.
Chromium: Can cause respiratory problems, skin irritation, and allergic reactions.
Copper: Can irritate the respiratory tract and cause nausea and vomiting.
Dioxins and Furans: Highly toxic compounds that can cause cancer and other health problems.

The concentration of these chemicals in the smoke depends on the type of preservative used, the amount of wood burned, and the ventilation. However, even small amounts of these toxins can be harmful, especially to children, pregnant women, and people with respiratory problems.

Contaminated Ash

The ash from burning pressure-treated wood is also contaminated with toxic chemicals. If this ash is spread on gardens or used as fertilizer, it can contaminate the soil and plants, potentially exposing you to harmful substances through food.

Environmental Impact

Burning pressure-treated wood doesn’t just harm your health; it also harms the environment. The toxic chemicals released into the air can contribute to air pollution, and the contaminated ash can pollute the soil and water.

Data and Statistics

A study by the Environmental Protection Agency (EPA) found that burning CCA-treated wood releases arsenic into the air at levels that can pose a significant health risk.
Research has shown that exposure to arsenic can increase the risk of lung cancer by as much as 30%.
The EPA estimates that millions of pounds of pressure-treated wood are disposed of each year, and a significant portion of this is burned illegally.

Health Risks Associated with Burning Pressure-Treated Wood

The health risks associated with burning pressure-treated wood are serious and should not be taken lightly.

Short-Term Effects

Short-term exposure to the fumes from burning pressure-treated wood can cause:

Headaches

Dizziness
Respiratory irritation (coughing, wheezing, shortness of breath)
Skin irritation
Eye irritation

Long-Term Effects

Long-term exposure to the chemicals released from burning pressure-treated wood can lead to more serious health problems, including:

Cancer: Arsenic is a known carcinogen, and exposure to it can increase the risk of lung cancer, skin cancer, bladder cancer, and other types of cancer.
Respiratory Diseases: Chronic exposure to the fumes can worsen asthma and other respiratory conditions.
Neurological Problems: Some studies have linked exposure to arsenic to neurological problems, such as memory loss and cognitive impairment.
Developmental Problems: Exposure to arsenic during pregnancy can harm the developing fetus.

Vulnerable Populations

Certain populations are more vulnerable to the health effects of burning pressure-treated wood:

Children: Children are more susceptible to the effects of toxins because their bodies are still developing.
Pregnant Women: Exposure to toxins during pregnancy can harm the developing fetus.
People with Respiratory Problems: People with asthma, COPD, or other respiratory conditions are more likely to experience respiratory irritation from the fumes.
People with Weakened Immune Systems: People with weakened immune systems may be more susceptible to the effects of toxins.
