The Hidden Dangers of Treated Wood

Treated wood is lumber that has been infused with chemicals to protect it from rot, insects, and fungal decay. This process extends the lifespan of the wood, making it ideal for outdoor applications like decks, fences, and landscaping. However, these chemicals are also what make burning treated wood so hazardous.

What’s in Treated Wood?

The specific chemicals used in treated wood vary depending on the type of treatment and the age of the wood. Here are some of the most common:

• Chromated Copper Arsenate (CCA): Once the industry standard, CCA-treated wood is now largely phased out for residential use in many countries, including the United States and Canada. However, it can still be found in older structures and industrial applications. CCA contains arsenic, a known carcinogen.
• Alkaline Copper Quaternary (ACQ): A common alternative to CCA, ACQ uses copper and quaternary ammonium compounds to protect wood. While less toxic than CCA, ACQ can still release harmful chemicals when burned.
• Copper Azole (CA): Another CCA alternative, CA also uses copper and an azole fungicide. Like ACQ, it’s considered less toxic than CCA but still poses risks when burned.
• Creosote: Used primarily on railroad ties and utility poles, creosote is a complex mixture of chemicals derived from coal tar. It’s a known carcinogen and should never be burned in residential settings.

The Health Risks of Burning Treated Wood

Burning treated wood releases these chemicals into the air as toxic fumes and ash. Inhaling these fumes can cause a range of health problems, from mild irritation to severe and potentially life-threatening conditions.

• Short-Term Effects: Exposure to the fumes from burning treated wood can cause:
  • Eye, nose, and throat irritation
  • Coughing and wheezing
  • Headaches and dizziness
  • Nausea and vomiting
• Long-Term Effects: Prolonged or repeated exposure to the chemicals in treated wood smoke can lead to more serious health problems, including:
  • Cancer (especially lung, skin, and bladder cancer)
  • Respiratory problems (such as asthma and bronchitis)
  • Neurological damage
  • Developmental problems in children

Data and Statistics:

• A study by the Environmental Protection Agency (EPA) found that burning CCA-treated wood can release arsenic into the air at levels that exceed safe exposure limits.
• The International Agency for Research on Cancer (IARC) classifies arsenic and creosote as known human carcinogens.

The Environmental Impact

Burning treated wood doesn’t just harm human health; it also damages the environment. The ash produced from burning treated wood contains concentrated levels of toxic chemicals that can contaminate soil and water.

• Soil Contamination: When ash from treated wood is disposed of improperly (e.g., in a garden or compost pile), the chemicals can leach into the soil, poisoning plants and potentially entering the food chain.
• Water Contamination: If ash from treated wood is washed into waterways, it can contaminate drinking water sources and harm aquatic life.
• Air Pollution: Burning treated wood releases harmful pollutants into the atmosphere, contributing to air pollution and exacerbating respiratory problems in vulnerable populations.

Identifying Treated Wood: A Visual Guide

One of the biggest challenges in avoiding treated wood is being able to identify it. Here are some tips to help you distinguish treated wood from untreated wood:

• Color: Treated wood often has a greenish or brownish tint due to the chemicals used in the treatment process. However, the color can fade over time, making it less reliable as a sole indicator.
• Tags and Stamps: Look for tags or stamps on the wood that indicate the type of treatment used. These markings often include abbreviations like “CCA,” “ACQ,” or “CA.”
• Smell: Treated wood may have a chemical odor, especially when freshly cut or burned.
• Age: Older wood is more likely to have been treated with CCA, so be extra cautious when handling wood from older structures.
• Use: Consider the original purpose of the wood. Lumber used for outdoor projects like decks, fences, and landscaping is likely to be treated. Railroad ties and utility poles are almost always treated with creosote.

Personal Story: I remember once salvaging some old lumber from a demolished deck. At first glance, it looked like regular wood, but then I noticed a faint greenish hue and a stamp that read “CCA.” I immediately knew it was treated and disposed of it properly, avoiding a potentially dangerous situation.

Safe Alternatives to Burning Treated Wood

Now that we’ve established the dangers of burning treated wood, let’s explore some safe and sustainable alternatives:

• Untreated Wood: The best option is always to burn untreated wood from sustainable sources. This includes firewood, scrap lumber from woodworking projects, and fallen branches from your yard.
• Kiln-Dried Wood: Kiln-dried wood is wood that has been dried in a kiln to reduce its moisture content. This makes it easier to burn and produces less smoke.
• Manufactured Fire Logs: These logs are made from compressed sawdust and wax and are designed to burn cleanly and efficiently.
• Natural Gas or Propane Fireplaces: If you’re looking for a convenient and clean-burning option, consider a natural gas or propane fireplace.

Data and Statistics:

• According to the EPA, burning dry, untreated wood is the cleanest and most efficient way to burn wood for heating.
• Kiln-dried wood typically has a moisture content of 20% or less, compared to green wood, which can have a moisture content of 50% or more.

Safe Woodworking Practices: Protecting Yourself and Your Family

Beyond avoiding treated wood, there are several other woodworking practices you can adopt to protect yourself and your family from harmful chemicals and dust.

• Wear a Respirator: When working with wood, always wear a NIOSH-approved respirator to protect yourself from inhaling dust and fumes.
• Use Dust Collection Systems: Invest in a dust collection system to remove dust from your workshop. This will help improve air quality and reduce your exposure to harmful particles.
• Work in a Well-Ventilated Area: Ensure your workshop is well-ventilated to allow for the removal of dust and fumes.
• Wash Your Hands Regularly: Wash your hands thoroughly after working with wood and before eating or drinking.
• Dispose of Wood Waste Properly: Dispose of wood waste in a responsible manner. Do not burn treated wood or dispose of it in your garden or compost pile.

Personal Story: I used to be lax about wearing a respirator when sanding wood, thinking it wasn’t a big deal. But after developing a persistent cough and experiencing frequent nosebleeds, I realized I needed to take my respiratory health more seriously. Now, I never work with wood without wearing a respirator, and I’ve noticed a significant improvement in my overall health.

The Cost of Safety: Budgeting for Safe Wood Practices

Now, let’s talk about the financial side of things. While safety should always be your top priority, it’s also important to consider the cost of safe wood practices.

The Price of Untreated Wood

Untreated wood can be more expensive than treated wood, depending on the species and grade. However, the long-term health and environmental benefits outweigh the initial cost difference.

• Firewood Costs: The price of firewood varies depending on your location, the type of wood, and the quantity you purchase. On average, a cord of seasoned hardwood firewood can cost anywhere from $200 to $400.
• Lumber Costs: The price of lumber also varies depending on the species and grade. Softwoods like pine and fir are typically less expensive than hardwoods like oak and maple.

Data and Statistics:

• According to the USDA Forest Service, the average price of hardwood lumber in the United States has been steadily increasing in recent years due to factors such as increased demand and supply chain disruptions.
• The price of firewood is often higher in urban areas due to transportation costs and limited availability.

Cost Comparison Table: Firewood Preparation Methods

Calculations and Formulas for Firewood Preparation

Let’s get a little technical. Understanding some basic calculations can help you estimate your firewood needs and costs more accurately.

• Estimating Firewood Volume: Firewood is typically sold by the cord. A cord is a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long, for a total volume of 128 cubic feet. To estimate the volume of a pile of wood, multiply the height, width, and length in feet and divide by 128.
• Estimating Drying Time: The drying time for firewood depends on the type of wood, the climate, and how well the wood is stacked and covered. As a general rule, hardwoods take longer to dry than softwoods. To estimate the drying time, consider the following factors:
  • Wood Species: Hardwoods like oak and maple can take 12 months or more to dry, while softwoods like pine and fir can dry in as little as 6 months.
  • Climate: Warm, dry climates are ideal for drying firewood.
  • Stacking Method: Stack firewood in a single row with plenty of air circulation.
  • Covering: Cover the top of the stack with a tarp to protect the wood from rain and snow.

Example Calculation:

Let’s say you have a pile of firewood that measures 6 feet high, 5 feet wide, and 10 feet long. To estimate the volume of the pile, multiply the dimensions:

6 feet x 5 feet x 10 feet = 300 cubic feet

Then, divide by 128 to convert to cords:

300 cubic feet / 128 cubic feet/cord = 2.34 cords

Therefore, the pile contains approximately 2.34 cords of firewood.

Challenges Faced by Small-Scale Loggers and Firewood Suppliers

It’s important to acknowledge the challenges faced by small-scale loggers and firewood suppliers, who often operate on tight margins and face stiff competition from larger companies.

• Rising Costs: The cost of fuel, equipment, and insurance has been steadily increasing in recent years, putting pressure on small businesses.
• Regulatory Burdens: Small-scale loggers and firewood suppliers often face complex regulatory requirements, such as permits and environmental regulations.
• Competition: Small businesses must compete with larger companies that have greater resources and economies of scale.
• Seasonality: The demand for firewood is seasonal, which can make it difficult for small businesses to maintain a steady income.

Personal Story: I’ve seen many small-scale loggers struggle to stay afloat due to rising costs and regulatory burdens. It’s important to support these local businesses by buying firewood from them whenever possible.
