How far from a bulldozer working in the forest should you keep?
* Describe the “Dead Man Zone” and its potential consequences - The dead man zone is an area away from, but near to, the actual fire. Hazardous as if there is a change in wind direction, the fire flank can quickly become the head fire burning directly at you with an increased velocity and intensity.
Why is direct attack on grass fires often most effective from the burnt side of the fire edge?
* As a general rule, what is the maximum flame height that may allow a direct attack? approx 1.5m or less
