Does Treated Wood Burn? (5 Toxic Dangers Every Logger Knows)
Let’s get straight to the point: Yes, treated wood will burn. But just because it can burn doesn’t mean it should. The real question isn’t whether it’s combustible, but what happens when you set it ablaze.
What is Treated Wood Anyway?
Before delving into the dangers, let’s clarify what “treated wood” actually means. Treated wood is lumber that has been infused with chemical preservatives to protect it from rot, decay, and insect infestation. These chemicals are designed to extend the lifespan of the wood, particularly when it’s used in outdoor applications like decks, fences, and landscaping.
The most common type of treated wood you’ll encounter is pressure-treated lumber, which has been forced with preservatives under high pressure. This process ensures that the chemicals penetrate deep into the wood fibers, providing long-lasting protection.
Other types of treated wood may include:
- Borate-treated wood: Used primarily for interior applications to protect against insects.
- Creosote-treated wood: Commonly used for railroad ties and utility poles.
- Chromated Copper Arsenate (CCA) treated wood: Older, but still potentially around.
It’s crucial to understand that the chemicals used in treated wood are inherently toxic. They’re designed to kill living organisms that would otherwise degrade the wood. That’s why burning it releases those toxins into the air, posing a significant threat to human health and the environment.
The 5 Toxic Dangers of Burning Treated Wood
Now, let’s get into the nitty-gritty.
1. Arsenic Exposure
Arsenic is a naturally occurring element that is highly toxic to humans. It was a key component of CCA-treated wood, which was widely used until the early 2000s. While CCA has been phased out for most residential applications, it’s still possible to encounter it in older structures.
When CCA-treated wood is burned, the arsenic is released into the air as a fine particulate matter. This arsenic-laden smoke can be inhaled, leading to a range of health problems.
Health Risks of Arsenic Exposure:
- Respiratory problems: Inhaling arsenic can irritate the lungs and cause coughing, wheezing, and shortness of breath.
- Skin irritation: Direct contact with arsenic can cause skin rashes, itching, and even chemical burns.
- Cancer: Long-term exposure to arsenic has been linked to an increased risk of lung, bladder, and skin cancer.
- Neurological effects: Arsenic can damage the nervous system, leading to numbness, tingling, and weakness in the extremities.
- Cardiovascular problems: Arsenic exposure has been associated with an increased risk of heart disease and stroke.
Data Points and Statistics:
- A study published in the Journal of Environmental Health found that burning CCA-treated wood can release up to 20 times the amount of arsenic considered safe by the EPA.
- The EPA estimates that even short-term exposure to high levels of arsenic can cause nausea, vomiting, and diarrhea.
- The World Health Organization (WHO) considers arsenic to be a known human carcinogen.
My Experience:
I remember one time when a construction crew was tearing down an old deck near my property. They were burning the debris, and I immediately noticed the acrid, chemical smell. I walked over and saw that they were burning CCA-treated lumber. I explained the dangers to them, and they were shocked. They had no idea they were exposing themselves to such a serious health hazard.
2. Chromium Poisoning
Chromium is another metal that was used in CCA-treated wood. While chromium is an essential nutrient in small amounts, it can be toxic at higher concentrations.
When CCA-treated wood is burned, chromium is released into the air as a particulate matter. This chromium-laden smoke can be inhaled, leading to a range of health problems.
Health Risks of Chromium Exposure:
- Respiratory problems: Inhaling chromium can irritate the lungs and cause coughing, wheezing, and shortness of breath.
- Skin irritation: Direct contact with chromium can cause skin rashes, itching, and even chemical burns.
- Kidney damage: Long-term exposure to chromium has been linked to an increased risk of kidney damage.
- Liver damage: Chromium can also damage the liver, leading to jaundice and other complications.
- Cancer: Some forms of chromium are known carcinogens.
Data Points and Statistics:
- A study published in the Journal of Toxicology and Environmental Health found that burning CCA-treated wood can release significant amounts of chromium into the air.
- The EPA has set limits on the amount of chromium that can be present in drinking water due to its potential health risks.
- The National Institute for Occupational Safety and Health (NIOSH) considers chromium to be a potential occupational carcinogen.
Expert Insight:
“Chromium exposure from burning treated wood is a serious concern,” says Dr. Emily Carter, a toxicologist at the University of Washington. “The particles released can be easily inhaled, leading to both short-term and long-term health problems.”
3. Copper Contamination
Copper is a metal that is used in many types of treated wood, including ACQ (Alkaline Copper Quaternary) and CA (Copper Azole). These treatments are designed to protect the wood from fungal decay and insect infestation.
When copper-treated wood is burned, copper is released into the air as a particulate matter. This copper-laden smoke can be inhaled, leading to a range of health problems.
Health Risks of Copper Exposure:
- Respiratory problems: Inhaling copper can irritate the lungs and cause coughing, wheezing, and shortness of breath.
- Gastrointestinal problems: Ingesting copper can cause nausea, vomiting, and diarrhea.
- Liver damage: Long-term exposure to copper can damage the liver, leading to jaundice and other complications.
- Kidney damage: Copper can also damage the kidneys, leading to kidney failure.
- Neurological effects: In rare cases, copper exposure can cause neurological problems, such as seizures and coma.
Data Points and Statistics:
- A study published in the Journal of Hazardous Materials found that burning copper-treated wood can release significant amounts of copper into the air.
- The EPA has set limits on the amount of copper that can be present in drinking water due to its potential health risks.
- The Agency for Toxic Substances and Disease Registry (ATSDR) has identified copper as a potential environmental contaminant.
Case Study:
In 2018, a family in Oregon experienced severe health problems after burning copper-treated wood in their wood stove. The family members suffered from respiratory problems, nausea, and vomiting. The local health department investigated the incident and determined that the copper exposure was the likely cause of their illness.
4. Dioxin Formation
Dioxins are a group of highly toxic chemicals that are formed as byproducts of combustion processes, particularly when chlorine is present. Many types of treated wood contain chlorine-based preservatives, which can lead to dioxin formation when the wood is burned.
Dioxins are persistent environmental pollutants, meaning they don’t break down easily and can accumulate in the environment and in living organisms. They are also highly toxic, even at very low concentrations.
Health Risks of Dioxin Exposure:
- Cancer: Dioxins are known human carcinogens.
- Reproductive and developmental problems: Dioxins can interfere with hormone function and cause reproductive and developmental problems.
- Immune system suppression: Dioxins can weaken the immune system, making people more susceptible to infections.
- Skin problems: Dioxins can cause skin rashes, discoloration, and other skin problems.
- Liver damage: Dioxins can damage the liver, leading to jaundice and other complications.
Data Points and Statistics:
- The World Health Organization (WHO) considers dioxins to be among the most toxic chemicals known to science.
- The EPA has classified dioxins as a known human carcinogen.
- A study published in the Environmental Science & Technology found that burning treated wood can release significant amounts of dioxins into the air.
Personal Story:
I once worked on a logging operation where the crew was burning treated wood scraps in an open pit. I knew this was a bad idea, but I didn’t have the authority to stop them. I reported the incident to the local environmental agency, and they came out and shut down the burning operation. It was a small victory, but it made me realize how important it is to be vigilant about preventing the burning of treated wood.
5. Environmental Contamination
Burning treated wood doesn’t just pose a threat to human health; it also contaminates the environment. The ash produced from burning treated wood contains concentrated levels of toxic chemicals, which can leach into the soil and water.
Environmental Impacts of Burning Treated Wood:
- Soil contamination: The ash from burning treated wood can contaminate the soil with arsenic, chromium, copper, and other toxic chemicals. This can harm plants and animals that come into contact with the contaminated soil.
- Water contamination: The toxic chemicals in the ash can leach into the groundwater and surface water, contaminating drinking water supplies and harming aquatic life.
- Air pollution: Burning treated wood releases particulate matter and other pollutants into the air, contributing to air pollution and respiratory problems.
- Ecosystem disruption: The toxic chemicals released from burning treated wood can disrupt ecosystems and harm wildlife.
Data Points and Statistics:
- The EPA estimates that burning treated wood can release up to 10 times the amount of pollutants compared to burning untreated wood.
- A study published in the Journal of Environmental Quality found that the ash from burning treated wood can significantly increase the levels of arsenic, chromium, and copper in the soil.
- The U.S. Geological Survey (USGS) has documented numerous cases of water contamination from the improper disposal of treated wood.
Unique Insight:
One aspect often overlooked is the impact on the immediate micro-environment. Think about your garden. If you’re using the ash from burned treated wood as fertilizer (a terrible idea, but some people do it!), you’re directly poisoning the soil and potentially contaminating the food you grow.
How to Identify Treated Wood
One of the best ways to avoid the dangers of burning treated wood is to learn how to identify it. Here are some tips:
- Look for a stamp: Treated wood is typically stamped with information about the type of treatment, the manufacturer, and the intended use.
- Check the color: Some treated wood has a greenish tint, which is a result of the copper-based preservatives.
- Smell the wood: Treated wood often has a distinct chemical odor.
- Consider the source: If you’re unsure whether wood is treated, err on the side of caution and assume that it is. Wood used for decks, fences, landscaping, and other outdoor applications is likely to be treated.
- When in doubt, don’t burn it: If you’re not sure whether a piece of wood is treated, don’t burn it. It’s better to be safe than sorry.
Proper Disposal Methods for Treated Wood
If you have treated wood that you need to dispose of, don’t burn it. Instead, follow these safe disposal methods:
- Landfill: The safest way to dispose of treated wood is to take it to a landfill that accepts construction debris.
- Recycling: Some recycling centers accept treated wood for reuse in industrial applications.
- Donation: If the treated wood is in good condition, you may be able to donate it to a construction project or a community organization.
- Professional removal: If you have a large amount of treated wood to dispose of, you may want to hire a professional waste removal service.
Important Note:
Never bury treated wood in your backyard or burn it in an open pit. These practices can contaminate the soil and water and pose a threat to human health.
Legal Ramifications
Beyond the health and environmental concerns, burning treated wood can also have legal ramifications. Many states and local municipalities have regulations in place that prohibit the burning of treated wood. Violators may be subject to fines and other penalties.
Example:
In California, it is illegal to burn treated wood in residential fireplaces and wood stoves. Violators can be fined up to \$500 per violation.
Alternative Fuel Sources
If you’re looking for alternative fuel sources for your fireplace or wood stove, consider these options:
- Untreated firewood: Untreated firewood is a safe and renewable fuel source. Make sure the wood is properly seasoned before burning it.
- Pellet stoves: Pellet stoves burn wood pellets, which are made from compressed sawdust and other wood waste.
- Gas fireplaces: Gas fireplaces burn natural gas or propane, which are cleaner-burning fuels than wood.
- Electric fireplaces: Electric fireplaces are a convenient and safe alternative to traditional fireplaces.
The Impact on Small Workshops and Independent Loggers
I know that for many small workshops and independent loggers, the temptation to burn scrap treated wood can be strong. It seems like an easy way to get rid of waste and save money on heating. However, the long-term costs far outweigh any short-term benefits.
Not only are you putting your health and the health of your workers at risk, but you’re also damaging the environment and potentially violating the law. In the long run, it’s simply not worth it.
Recommendation:
Invest in proper waste disposal methods and explore alternative fuel sources. Your health, your business, and the environment will thank you.
Actionable Conclusions and Next Steps
Okay, so you’re armed with the knowledge. Now what? Here’s what I recommend:
