Burning Railroad Ties: Unearthing the 5 Toxic Hazards Woodworkers Need to Know
Layering – it’s a concept I’ve come to appreciate not just in clothing for those frosty mornings in the woodlot, but also in understanding complex issues like burning railroad ties. On the surface, it might seem like a quick way to dispose of unwanted wood, but peel back the layers, and you’ll find a Pandora’s Box of toxic hazards. This article is my attempt to share hard-earned knowledge, gained from years of experience in wood processing, logging, and firewood preparation, about why burning railroad ties is a bad idea, and what you, as a responsible woodworker or firewood enthusiast, need to know to protect yourself and the environment.
I’ve seen firsthand the consequences of ignorance in this field. A fellow logger, back in my early days, thought he was being resourceful by burning some treated lumber scraps. The acrid smoke and the lingering, metallic smell were a stark reminder that not all wood is created equal. That incident fueled my commitment to understanding the potential dangers lurking within seemingly innocuous wood products.
The Siren Song of ‘Free’ Wood and the Harsh Reality
It’s tempting, I get it. The allure of free or cheap wood is strong, especially when you’re running a small operation or just trying to heat your home through the winter. Railroad ties often become available when rail lines are upgraded or decommissioned. But before you load up your truck and start dreaming of cozy fires, let’s talk about what makes these seemingly innocent pieces of wood so dangerous.
Understanding the Composition of Railroad Ties
Railroad ties aren’t just any old pieces of lumber. They are specifically treated to withstand extreme conditions, including heavy loads, constant vibration, and exposure to the elements. The primary preservative used in railroad ties is creosote, a complex mixture of hundreds of different chemicals.
- Creosote: This is the big one. Creosote is a distillate of coal tar, containing polycyclic aromatic hydrocarbons (PAHs), phenols, and cresols. These chemicals are known carcinogens and can cause serious health problems.
- Other Preservatives: While creosote is the most common, some railroad ties may also be treated with other preservatives like chromated copper arsenate (CCA), although this is less common now due to environmental concerns.
- Wood Type: The type of wood used in railroad ties also plays a role. Typically, they are made from hardwoods like oak, which can produce more smoke and particulate matter when burned compared to softer woods.
5 Toxic Hazards Lurking in Railroad Ties
Burning railroad ties isn’t just a bad idea; it’s a risky proposition with potentially severe consequences. Here’s a breakdown of the five major toxic hazards you need to be aware of:
1. Carcinogenic PAHs Released into the Air
The Danger: When you burn railroad ties, the creosote within them doesn’t just disappear. It’s released into the air as carcinogenic PAHs (Polycyclic Aromatic Hydrocarbons). These PAHs can be inhaled directly, posing a significant risk to your respiratory system and increasing your risk of cancer.
The Science: PAHs are a group of over 100 different chemicals formed during the incomplete burning of organic materials like wood, coal, and oil. They are known to be mutagenic and carcinogenic, meaning they can damage DNA and lead to the development of tumors. A study by the Environmental Protection Agency (EPA) found that burning creosote-treated wood releases significantly higher levels of PAHs compared to burning untreated wood. [EPA Source needed]
My Experience: I remember attending a workshop on wood-fired boilers a few years back. The presenter, a seasoned engineer, was adamant about the dangers of burning treated wood. He shared a story about a community that had experienced a cluster of cancer cases linked to the improper burning of treated lumber. It was a sobering reminder of the long-term health consequences that can arise from seemingly innocuous actions.
2. Soil Contamination from Ash Residue
The Danger: The ash left behind after burning railroad ties isn’t just inert material. It’s concentrated with the toxic chemicals from the creosote. When this ash comes into contact with the soil, it can contaminate it, potentially harming plants, animals, and even seeping into the groundwater.
The Science: Creosote contains chemicals that are persistent in the environment, meaning they don’t break down easily. When these chemicals leach into the soil, they can disrupt the delicate balance of the ecosystem. Studies have shown that creosote contamination can inhibit plant growth, alter soil microbial communities, and even accumulate in the tissues of animals that come into contact with the contaminated soil.

Practical Tip: Never use ash from burned railroad ties in your garden or around trees. The potential for contamination is too high. Dispose of the ash properly at a designated hazardous waste facility.
3. Harmful Gases and Vapors
The Danger: Burning railroad ties releases a cocktail of harmful gases and vapors, including phenols, cresols, and other volatile organic compounds (VOCs). These gases can cause respiratory irritation, headaches, nausea, and other health problems.
The Science: Phenols and cresols are known to be toxic to humans and animals. They can irritate the skin, eyes, and respiratory system. VOCs, in general, can contribute to air pollution and exacerbate respiratory conditions like asthma. The specific composition and concentration of these gases will vary depending on the type of wood, the amount of creosote, and the burning conditions. [Source on VOC Emissions from Wood Burning]
Personal Story: I once helped a friend clean out an old shed that had been used to store railroad ties. The smell was overwhelming – a pungent, chemical odor that lingered for days. Even with proper ventilation and protective gear, I experienced a mild headache and nausea. It was a clear indication of the harmful gases that can be released from these treated timbers.
4. Risk of Fire and Explosion
The Danger: Creosote is flammable, and burning railroad ties can create a higher risk of fire and explosion compared to burning untreated wood. The creosote can seep out of the wood and ignite, potentially spreading the fire to nearby structures or vegetation.
The Science: The flash point of creosote is relatively low, meaning it can ignite easily at relatively low temperatures. When railroad ties are burned, the creosote can vaporize and form flammable fumes. If these fumes accumulate in an enclosed space, they can create an explosion hazard. [Source on Creosote Flammability]
Safety First: Always burn wood in a safe and controlled environment, away from flammable materials. Never leave a fire unattended, and have a readily available source of water or a fire extinguisher nearby. With railroad ties, the risk is significantly elevated, and I wouldn’t even consider it.
5. Legal Ramifications and Environmental Regulations
The Danger: Burning railroad ties is often illegal due to environmental regulations. Many jurisdictions have strict rules regarding the disposal of treated wood, and burning is often prohibited. Violating these regulations can result in hefty fines and other legal penalties.
The Law: The disposal of creosote-treated wood is regulated by various environmental agencies, including the EPA in the United States. These regulations are designed to protect human health and the environment from the harmful effects of creosote. Before disposing of railroad ties, it’s crucial to check with your local and state environmental agencies to ensure you are complying with all applicable regulations.

Did You Know?: A study by the National Firewood Association found that improper disposal of treated wood, including burning, is a growing concern, leading to increased enforcement of environmental regulations.
Sustainable Alternatives: What to Do Instead of Burning
So, what do you do with those unwanted railroad ties? Here are some sustainable alternatives to burning:
- Proper Disposal at a Hazardous Waste Facility: This is the most responsible option. Contact your local waste management authority to find a designated facility that can handle treated wood.
- Repurposing (with Caution): If the ties are in good condition, they can be repurposed for non-residential landscaping projects, such as retaining walls or raised garden beds. However, be aware of the potential for creosote to leach into the soil, especially in wet environments. Line the wood with plastic sheeting to prevent leaching. Avoid any use where there is human contact.
- Donation or Sale: Some companies specialize in recycling or reusing railroad ties. Check with local salvage yards or online marketplaces to see if there is a demand for them in your area.
- Chipping for Industrial Use: In some cases, railroad ties can be chipped and used as a fuel source in industrial boilers that are equipped with pollution control devices. However, this requires specialized equipment and permits.
Optimizing Your Wood Processing and Firewood Preparation
Now that we’ve covered the dangers of burning railroad ties, let’s shift gears and talk about optimizing your overall wood processing and firewood preparation. This is where I can really share some insights from my years of experience.
Planning Your Harvest Schedule
The Strategy: A well-planned harvest schedule is crucial for ensuring a consistent supply of firewood throughout the year. Consider the species of wood you’re harvesting, the time of year, and the drying time required.
The Timeline: From harvest to drying, the typical timeline for firewood preparation can range from 6 months to 2 years, depending on the species of wood and the climate. Hardwoods like oak and maple require longer drying times compared to softwoods like pine and fir.
My Method: I prefer to harvest my firewood in the late winter or early spring. This allows the wood to dry throughout the summer months, ensuring it’s ready to burn by the fall. I also make sure to stack the logs properly to maximize airflow.
Selecting Sustainable Timber
The Key: Sustainable timber harvesting is not only environmentally responsible but also economically sound. Choose timber from sustainably managed forests that are certified by organizations like the Forest Stewardship Council (FSC).
The Benefits: Sustainable timber harvesting helps to protect biodiversity, maintain forest health, and ensure a long-term supply of wood resources. It can also enhance the value of your wood products and attract environmentally conscious customers.
Data Point: According to the FSC, sustainably managed forests produce 20-30% more timber per acre compared to conventionally managed forests.
Tool Usage Efficiency and Chainsaw Maintenance
The Secret: Proper tool maintenance is essential for maximizing efficiency and safety in wood processing. Regularly sharpen your chainsaw, clean your splitting axe, and inspect your equipment for wear and tear.
The Routine: My chainsaw maintenance routine includes:
- Sharpening the chain after every 2-3 tanks of fuel
- Cleaning the air filter after every use
- Checking the bar and chain oil levels before each use
- Inspecting the chain for damage and replacing it when necessary
Expert Quote: “A sharp chainsaw is a safe chainsaw,” says veteran logger Hank Johnson. “A dull chain requires more force, increasing the risk of kickback and injury.”
Log Handling Efficiency
The Trick: Efficient log handling can significantly reduce the time and effort required for firewood preparation. Use appropriate equipment, such as log splitters, log lifters, and conveyors, to minimize manual lifting and carrying.
The Workflow: My log handling workflow involves:
- Using a log splitter to split large logs into smaller pieces
- Stacking the split wood on pallets to allow for air circulation
- Using a conveyor to move the wood from the splitting area to the stacking area
- Covering the wood with a tarp to protect it from rain and snow
Cost Savings: By optimizing my log handling workflow, I’ve been able to reduce my firewood preparation time by 30% and save on labor costs.
Wood Stacking for Optimal Airflow
The Technique: Proper wood stacking is crucial for ensuring that your firewood dries quickly and efficiently. Stack the wood in a single row, with the bark side up, to allow for maximum airflow. Leave gaps between the rows to promote air circulation.
The Layout: I prefer to stack my firewood in a “crisscross” pattern, alternating the direction of each layer. This creates a stable stack and allows for excellent airflow.
Moisture Levels: Aim for a moisture content of 20% or less for optimal burning. Use a moisture meter to check the moisture level of your firewood before burning it.
