31
Q

The side opposite the head of the fire, which is often close to the area of origin.

32
Q

A job and training reference for personnel operating at a wildland fire. It may also be used for all-hazard incident response.

33
Q

A method of wildland fire attack in which the control line is located along natural fuel breaks, at favorable breaks in the topography, or at considerable distance from the fire, and the intervening fuel is burned out.

A

Indirect attack

34
Q

An unburned area surrounded by fire.

A

Island

35
Q

Fuels that provide vertical continuity between the ground and the tops of trees or shrubs, thereby allowing fire to move with relative ease.

A

38
Q

A method of attack in which the control line is located parallel to the fire edge, at a distance of about 5 to 50 ft (1.5 to 15 m) from the fire. The intervening fuel usually burns out as the fire moves alongside the fire control line but can also burn out with the main fire.
