The Forest Service and Smokey the Bear offer the following tips for building and putting out a campfire: Once you have a strong fire going, add larger pieces of dry wood to keep it burning steadily.
Keep your fire to a manageable size. Make sure children and pets are supervised when near the fire.
Never leave a campfire unattended. Use dry wood, not live trees or branches cut from live trees. To extinguish a campfire, allow the wood to burn completely to ash if possible. Pour water on the fire, drowning all embers, not just any that are red.
Pour water until any hissing sounds stop.
Stir the ashes and embers with a shovel.
Scrape sticks and logs to remove any embers.
Make sure all materials are wet and cold to the touch. If you don’t have water, you can suffocate the fire by adding loose dirt.
