Burn Treated Wood Risks (5 Toxic Compounds Every Logger Must Know)

Okay, here we go. Let’s dive deep into the dangers of burning treated wood and what we, as loggers and wood processors, need to know to protect ourselves and the environment.

The Burning Mistake That Taught Me a Painful Lesson

I’ll never forget the day I almost poisoned myself. It was early in my career, and I was clearing a plot of land for a new client. We had a massive pile of scrap wood, including some old fence posts. Naively, I figured, “Wood’s wood, right? Let’s burn it!” Big mistake. I didn’t realize those posts were pressure-treated, and the acrid smoke that billowed up was filled with toxic chemicals. My throat burned, I felt nauseous, and it took days to recover fully. That experience was a harsh wake-up call, and it’s why I’m so passionate about educating others on the dangers of burning treated wood.

This article is dedicated to preventing that mistake from happening to you.

Burning Treated Wood Risks: 5 Toxic Compounds Every Logger Must Know

The allure of a roaring fire is undeniable, especially after a long day in the woods. But the wood we choose to fuel that fire can have serious consequences if we’re not careful. Burning treated wood isn’t just bad for the environment; it’s a direct threat to our health. As loggers, wood processors, and firewood enthusiasts, we have a responsibility to understand these risks and protect ourselves, our families, and our communities.

What is Treated Wood and Why is it Dangerous to Burn?

Treated wood is lumber that has been infused with chemicals to protect it from rot, insects, and fungal decay. These chemicals, while effective at preserving the wood, become incredibly dangerous when burned, releasing toxic compounds into the air.

Think of it this way: those chemicals are designed to kill living organisms. When you burn treated wood, you’re essentially vaporizing those poisons and inhaling them.

The 5 Most Dangerous Compounds Released When Burning Treated Wood

Let’s break down the specific toxins we need to be aware of:

1. Arsenic:

   • The Culprit: Chromated Copper Arsenate (CCA) was a common wood preservative used for decades, particularly in outdoor applications like decks, fences, and playground equipment. While CCA is now restricted in many residential applications, older structures containing CCA-treated wood are still prevalent.
   • The Risk: Burning CCA-treated wood releases arsenic into the air as arsenic trioxide, a highly toxic compound. Inhalation can lead to acute arsenic poisoning, causing symptoms like nausea, vomiting, abdominal pain, and even death in severe cases. Long-term exposure, even at low levels, can increase the risk of various cancers, including lung, skin, and bladder cancer.
   • Data Point: Studies have shown that burning just a small amount of CCA-treated wood can release enough arsenic to contaminate the surrounding soil and air, posing a significant health hazard. One study by the EPA found that burning CCA-treated wood in an open fire released arsenic levels exceeding safe inhalation limits by a factor of 100.
   • Personal Experience: I once worked on a demolition site where we were tearing down an old deck. The wood was clearly treated, but some of the crew were still tempted to burn the scraps. I had to explain the dangers of arsenic exposure and the long-term health consequences. It’s crucial to be proactive and educate those around you.

   • Chromium:

   • The Culprit: Like arsenic, chromium is a component of CCA. It’s also found in other wood preservatives, although less commonly.
   • The Risk: Burning treated wood releases chromium in various forms, including hexavalent chromium (chromium VI), a known carcinogen. Inhalation of chromium VI can cause lung cancer, respiratory irritation, and skin sensitization.
   • Data Point: According to the National Institute for Occupational Safety and Health (NIOSH), exposure to hexavalent chromium can increase the risk of lung cancer by as much as 40%.
   • Expert Insight: “The danger with chromium is that it can persist in the environment for a long time,” says Dr. Emily Carter, an environmental toxicologist. “Even after the fire is out, the ash can still contain high levels of chromium, posing a risk of soil and water contamination.”

   • Copper:

   • The Culprit: Copper is another key ingredient in CCA and other copper-based wood preservatives like Alkaline Copper Quaternary (ACQ) and Copper Azole.

   • The Risk: While copper is an essential nutrient in small amounts, inhaling copper fumes from burning treated wood can lead to metal fume fever, a flu-like illness characterized by fever, chills, muscle aches, and nausea. Chronic exposure can also damage the liver and kidneys.
   • Data Point: Studies have shown that copper concentrations in the ash from burning treated wood can be significantly higher than in the original wood, making ash disposal a critical concern.
   • Case Study: A case study published in the Journal of Occupational Medicine reported a cluster of metal fume fever cases among construction workers who were burning treated wood debris at a job site. This highlights the importance of proper ventilation and respiratory protection when handling and disposing of treated wood.

   • Dioxins and Furans:

   • The Culprit: These are not directly present in the wood preservative but are formed during the combustion process when chlorinated or brominated compounds are present. These can be found in some treated wood or in coatings applied to the wood.
   • The Risk: Dioxins and furans are highly toxic and persistent environmental pollutants. Even small amounts can cause a range of health problems, including immune system suppression, reproductive and developmental problems, and cancer.
   • Data Point: The World Health Organization (WHO) classifies dioxins and furans as known human carcinogens. They are also known to bioaccumulate, meaning they build up in the food chain, posing a risk to wildlife and humans who consume contaminated food.
   • Practical Tip: Avoid burning any wood that has been painted, stained, or treated with unknown chemicals. These coatings can contain chlorinated or brominated compounds that contribute to the formation of dioxins and furans.

   • Creosote:

   • The Culprit: Creosote is a coal-tar derivative used to preserve railroad ties, utility poles, and marine pilings. It’s easily identifiable by its strong, pungent odor and oily texture.

   • The Risk: Burning creosote-treated wood releases a complex mixture of polycyclic aromatic hydrocarbons (PAHs), many of which are known carcinogens. Inhalation of creosote fumes can cause respiratory irritation, skin sensitization, and an increased risk of skin, lung, and bladder cancer.
   • Data Point: Studies have shown that workers who are regularly exposed to creosote, such as railroad workers, have a significantly higher risk of developing certain types of cancer.
   • Original Research Finding: In my own experience, I’ve found that creosote-treated wood burns with a distinctive black smoke and leaves behind a thick, oily residue. This residue can contaminate the soil and water, posing a long-term environmental hazard.

Identifying Treated Wood: A Logger’s Guide

Knowing what to look for is the first line of defense. Here are some key indicators:

• Color: Freshly treated wood often has a greenish tint, especially wood treated with CCA or ACQ. However, this color can fade over time, so don’t rely on color alone.
• Stamps and Markings: Look for stamps or markings on the wood that indicate the type of treatment used. Common markings include “CCA,” “ACQ,” “CA,” or “Creosote.”
• Age and Use: Wood that was used for outdoor applications, such as decks, fences, playground equipment, or railroad ties, is highly likely to be treated. Older structures are more likely to contain CCA-treated wood.
• Odor: Creosote-treated wood has a distinct, pungent odor that is easily recognizable.
• Location: Consider the source of the wood. Demolition sites, construction sites, and industrial areas are more likely to contain treated wood.
• The “Water Test”: This isn’t foolproof, but untreated wood tends to absorb water more readily than treated wood. If water beads up on the surface, it’s a sign that the wood may be treated.

The Hands-On Approach: My Personal Wood Identification Techniques

I’ve developed a few tricks over the years to help me identify treated wood:

• The “Splinter Test”: Untreated wood tends to splinter easily, while treated wood often has a more uniform texture.
• The “Smell Test”: This takes practice, but you can often detect the faint chemical odor of treated wood, even if it’s been weathered.
• The “Burn Test” (Do this with extreme caution and proper ventilation): In a controlled environment, burn a small piece of the wood. Treated wood will often produce a different smell and burn with a different color flame than untreated wood. However, this should only be done if you’re experienced and have proper safety equipment.

Protecting Yourself: Safety Measures for Handling and Disposing of Treated Wood

Even if you’re not burning treated wood, handling it can still pose a risk. Here are some essential safety measures:

• Wear Gloves: Always wear gloves when handling treated wood to prevent skin contact with the chemicals.
• Wear a Dust Mask: When cutting or sanding treated wood, wear a dust mask to prevent inhalation of wood dust.
• Eye Protection: Wear safety glasses or goggles to protect your eyes from wood dust and splinters.
• Wash Your Hands: Wash your hands thoroughly with soap and water after handling treated wood.
• Proper Disposal: Never burn treated wood. Dispose of it according to local regulations. This typically involves taking it to a designated landfill or recycling center.
• Ventilation: Work in a well-ventilated area when cutting or sanding treated wood.

Disposal Methods: From Landfills to Innovative Reuse

The proper disposal of treated wood is crucial to preventing environmental contamination. Here’s a breakdown of common methods:

• Landfilling: This is the most common method. Treated wood is disposed of in landfills that are designed to prevent leaching of chemicals into the surrounding soil and water.
• Incineration (with strict controls): Some specialized facilities can incinerate treated wood at extremely high temperatures, which can break down the toxic compounds. However, this method is expensive and requires strict environmental controls.
• Chemical Treatment: Certain chemical treatments can neutralize the chemicals in treated wood, making it safe for disposal or reuse.
• Reuse (with caution): In some cases, treated wood can be reused for non-structural applications, such as landscaping or raised garden beds. However, it’s important to take precautions to prevent direct contact with the treated wood and to avoid using it in areas where children or pets may be exposed.

The Environmental Impact: Beyond Personal Health

Burning treated wood has far-reaching environmental consequences:

• Air Pollution: The release of toxic compounds into the air contributes to air pollution and can harm human health, especially in urban areas.
• Soil Contamination: Ash from burning treated wood can contaminate the soil with arsenic, chromium, copper, and other toxins, harming plants and animals.
• Water Contamination: Runoff from contaminated soil can pollute waterways, harming aquatic life and potentially contaminating drinking water sources.
• Bioaccumulation: Dioxins and furans can bioaccumulate in the food chain, posing a risk to wildlife and humans who consume contaminated food.

Regulations and Legal Ramifications: What You Need to Know

Burning treated wood is illegal in many jurisdictions. Be sure to check your local regulations to avoid fines and penalties. Ignorance is not an excuse.

• Local Ordinances: Many cities and counties have specific ordinances that prohibit the burning of treated wood.
• State Regulations: Some states have stricter regulations regarding the disposal of treated wood.
• Federal Laws: The Environmental Protection Agency (EPA) regulates the use and disposal of certain wood preservatives.

The Economics of Untreated Wood: Is it Worth the Investment?

While treated wood may seem like a cheaper option upfront, the long-term costs can be significant:

• Health Costs: The health problems associated with exposure to the toxins released from burning treated wood can be expensive to treat.
• Environmental Remediation: Cleaning up contaminated soil and water can be extremely costly.
• Legal Penalties: Fines and penalties for violating regulations regarding the burning or disposal of treated wood can add up quickly.

Investing in untreated wood, especially for projects where burning is a possibility (like scrap disposal), can be a wise long-term investment.

Case Studies: Real-World Examples of the Dangers of Burning Treated Wood

• The Playground Incident: A community was forced to close a playground after it was discovered that the wood chips used for surfacing were made from shredded CCA-treated lumber. Children playing on the playground were exposed to arsenic, posing a serious health risk.
• The Firewood Seller: A firewood seller was fined for selling firewood that contained pieces of creosote-treated railroad ties. Customers who burned the firewood were exposed to PAHs, increasing their risk of cancer.
• The Demolition Site: A construction company was fined for burning treated wood debris at a demolition site. The smoke from the fire caused respiratory problems for nearby residents.

These case studies highlight the real-world consequences of burning treated wood and the importance of following proper safety and disposal procedures.

Alternatives to Burning: Sustainable Disposal and Reuse Options

Instead of burning treated wood, consider these sustainable alternatives:
