Never leave a campfire unattended. Even a small breeze could quickly cause the fire to spread. When finished with your fire, drown the fire with water. Make sure all embers, coals, and sticks are wet. Move rocks—there may be burning embers underneath. Stir the remains, add more water, and stir again. Be sure all burned material has been extinguished and cooled. If you do not have water, use dirt. Mix enough soil or sand with the embers. Continue adding and stirring until all material is cooled. Feel all materials with your bare hand. Make sure that no roots are burning. Do not bury your coals—they can smolder and break out. Treat charcoal briquettes like any other fire (see above).
When smoking is permitted outdoors, safe practices require at least a 3-foot clearing around the smoker. Grind out your cigarette, cigar, or pipe tobacco in the dirt. Never grind it on a stump or log. Use your ashtray while in your car. Smoking isn’t that necessary that you can’t go somewhere safe to do it.
Spark Arresters: All types of equipment and vehicles are required to have spark arresters. Chain saws, portable generators, cross-country vehicles, and trail bikes–to name a few–require spark arresters if used in or near grass, brush, or a wooded area. To make sure that the spark arrester is functioning properly, check with the dealer or contact your local Forest Service or State forestry office.
Vehicles can and will ignite grass. Always park on gravel roads or parking lots. If you must park on the grass because you have heavy equipment like soundsystem or tent, it’s a good idea to let the engine and exhaust cool down a little on some gravel before moving to the grass. While your vehicle is cooling go to the spot where you will be parking and dig a fireline about 5′ larger diameter than the vehicle on all sides. A fireline should be 2 feet wide and 1 foot deep. Deep enough to get past most of the grass roots. Buckets of sand or water should be placed near every vehicle, generator, and larger tent. Bigger vehicles should have more buckets.
