A fire treatment type. A prescribed fire to deliberately burn natural or modified concentrations (jackpots) of wildland fuels under specified environmental conditions, which allows the fire to be confined to a predetermined area and produces the fireline intensity and rate of spread required to attain planned resource Management Objectives.

Smoke produced by smoldering material. The flux of smoke originating well after the active flaming combustion period with little or no vertical buoyancy and, therefore, most susceptible to subsidence inversions and down-valley flows.

A foam generating device that mixes air at atmospheric pressure with foam solution in a nozzle chamber.

Used in some localities to specify fire set to spread against the wind in prescribed burning.

The greatly increased rate of water run off and soil movement from steep slopes that may follow removal of the vegetative cover by burning.

A line connecting points of equal atmospheric pressure on a weather map.

The visible physical features on a landscape (e.g., land, water, vegetation, animals, structures and other features).

The person who occupies such a station.

Supply of water at rest which does not provide a pressure head for fire suppression but which may be employed as a suction source for fire pumps (e.g., water in a reservoir, pond, or cistern).

The official delegation of authority to contracting officers and procurement officers establishing the dollar amount and type limits for acquisitions.
