Wood smoke pollution, whether it comes from recreational fires or wildfires, contains particulate matter pollution (PM2.5). Help reduce PM2.5 by following these guidelines when burning wood. During winter months, your air district may limit wood burning to help reduce PM2.5 pollution. Other year-round burning restrictions may also apply. Please be sure to check with your local air district before lighting a fire or burning outdoors.
- Start Your Fire with Softwood Kindling: Softwoods (pine, fir) are generally low in density, ignite easily, and burn fast and hot – which produces less smoke.
- Cover and Elevate Stored Wood: Keep dew and water off wood; avoid burning wet or moist wood because it will not only cause heavy smoke but is also a less efficient heat source.
- Watch Your Chimney for Smoke: If you see smoke, then the wood is not burning efficiently. The darker the smoke, the more pollutants it contains. Chimneys should be cleaned professionally to remove creosote buildup (creosote is a byproduct that can fuel a chimney fire that can burn down your house).
- Refrain from Burning Garbage, Plastic, Glossy Paper, or Painted or Treated Wood: These are always illegal to burn and are known to produce harmful fumes.
