Why Burning Railroad Ties Is a Toxic Hazard

Old railroad ties may seem like free firewood, but burning them releases dangerous chemicals into your air, soil, and water. Here's why you should never burn them—and how to dispose of them properly.

The Hidden Danger: Creosote

Railroad ties are pressure-treated with creosote, a coal-tar derivative that preserves wood but contains polycyclic aromatic hydrocarbons (PAHs), phenols, and cresols—all known carcinogens. When burned, these compounds become airborne toxic fumes that can cause respiratory irritation, skin damage, and long-term health risks for humans and animals.

Environmental Impact

• Ash and runoff contaminate soil and groundwater.
• Smoke affects neighbors and violates many local air-quality ordinances.
• Improper disposal can lead to fines.

Safe Disposal Options

Most landfills classify creosote-treated wood as special waste. Contact your municipal waste authority for designated drop-off sites—they often charge a fee but ensure proper containment. Never chip or mulch railroad ties for garden use; the chemicals leach into soil and harm plants.

Bottom line: The risks far outweigh any savings. Hire a professional removal service or haul ties to an approved facility. Your lungs—and your community—will thank you.
