 And now Chief Bob Cody with a special notice for the firefighters' brigade. Chief Cody. Hello, boys and girls. This is your friend Chief Cody, and I'd like to tell you how a backfire works. One of the ways to stop a fire, you know, is to take away the stuff it feeds on. And when you make a backfire, you get ahead of the main body of flame. You burn off a strip of grass or brush, and then when the main body of fire reaches that point, there's no fuel to keep it going and it begins to die.
