Open Burning Rules and Safety

Burning brush or debris is a common farm job, and escaped burns are a common cause of wildfire. Rules differ widely, so the first step is always to ask the right office before you light anything.

Who decides when and whether I can burn?

Open burning is regulated by states, counties, fire districts and sometimes cities. Some areas require a permit. Some ban burning on certain days or in dry seasons, and some prohibit certain materials entirely. Air quality agencies may also have rules.

Because these rules vary and change, do not rely on what a neighbor did last year. Call your local fire department, state forestry or natural resources agency, or county office and ask what is allowed on the day you plan to burn.

Fire danger can change within a day. A burn that was reasonable in the morning can become unsafe by afternoon if the wind rises or humidity drops, which is why checking conditions again just before you light matters.

• Check for permit requirements
• Ask about burn bans and restrictions
• Ask what materials you may burn

What conditions make a burn risky?

Wind, dry vegetation, low humidity and drought raise the chance that a fire escapes. Conditions can change within an hour. The National Weather Service posts forecasts and fire weather information, and local officials may issue red flag or burn ban notices.

If you are unsure, do not burn. Another day may be safer, and a postponed burn costs nothing compared with an escaped fire.

• Check the forecast and fire weather notices
• Watch the wind throughout the burn
• Postpone when in doubt

How do I plan a burn?

Choose a spot away from buildings, power lines, standing crop, trees and fuel storage. Clear a bare area around it. Decide how much material to burn at one time so you can control it. Tell neighbors and, where required, your fire department or dispatch center before you start.

Have a plan for what to do if it spreads, including who calls 911 and how you will reach water or tools. Official guidance from your state forestry agency can help with details.

Write down your plan, even briefly. Note the site, the people involved, the water source and the phone numbers to call. A written plan is easy to hand to a helper and easy to improve next time.

• Choose a safe site and clear around it
• Burn small amounts at a time
• Notify the people required to know

What should I have on hand?

Bring water, hand tools suited to the job and a charged phone. More than one person should be present. Wear clothing that does not melt and keeps skin covered. The right equipment for your situation is best learned from your fire department or forestry agency.

Never leave a burn unattended, and never use gasoline or other accelerants. They can cause sudden flare-ups that injure people.

Children and pets should stay well away from a burn site. Make sure everyone present knows where to stand and what to do if the wind changes.

• Water and tools nearby
• At least two people on site
• No accelerants

How do I put the fire out completely?

A fire that looks out can still hold heat. Stay until it is fully out and the area is cool by the method your forestry or fire agency recommends. Check the edges and any debris that rolled away. Return later to look again, especially if the wind rises.

Smoldering stumps, piles and roots can reignite long after. Treat the burn as unfinished until the official guidance says it is safe to leave.

Your fire department may be willing to talk through your plan or visit the site. Many welcome questions long before a fire starts.

• Stay until the burn is dead out
• Recheck the site later
• Watch for wind increases

What if the fire escapes?

Call 911 right away. Do not wait to see whether you can catch it. Give the dispatcher your location and tell them about the wind and what is nearby. Move people and animals out of the way and do not put yourself in front of a fire.

Many places hold the person who lit an escaped fire responsible for damage and costs. Check with your insurer and local authorities about what applies.

• Call 911 first
• Get clear and stay upwind of smoke
• Contact your insurer afterward

What are the alternatives to burning?

Chipping, composting, hauling to a disposal site or leaving brush in a place where it can break down may be possible. Your county extension office or solid waste office can list local choices.

If burning is the best option, choose the day and conditions with care and follow every local requirement.
