1. Be sure your match is out. Break it in two before you throw it away.

2. Be sure that pipe ashes and cigar or cigarette stubs are dead before

throwing them away. Never throw them into brush, leaves, or

needles. Don’t smoke while traveling through the woods.

3. Use fire grates at improved campgrounds and observe the rules for

building and extinguishing fires. Before building a campfire at

places where no grates are available, scrape away all inflammable

material from a place about 4 feet in diameter. Keep your fire

small and never build it against trees or logs, or near brush.
