The first step in campfire safety is to understand the difference between a campfire and a fire to dispose of debris. Campfires, solely for warming or cooking purposes, are smaller in size and comprised of clean and dry wood, contained within a designated fire ring or surrounded by rocks. Campfires are allowed anytime, except when Emergency Burning Restrictions are in effect. Burning in a fire ring with the intent to eliminate debris is NOT a campfire and does require a burning permit in DNR protection areas.
No matter what type of outdoor fire you have, check the daily burning restrictions for your area before ignition and never leave a fire unattended. Remember, you may be held responsible for all suppression costs and potentially any damages associated.
