1) Average maximum vertical extension of flames at the leading edge of the fire front. Occasional flashes that rise above the general level of flames are not considered. This distance is less than the flame length if flames are tilted due to wind or slope.


2) Small rotating windstorm of limited extent containing sand or dust. Synonymous with Whirlwind.


3) Fuel that contacts the surface of the ground; consists of duff, leaf and needle litter, dead branch material, downed logs, bark, tree cones, and lowstature living plants. These are the materials normally scraped away to construct a fireline. Synonymous with Ground Fuel.


4) Debris left after logging, pruning, thinning, or brush cutting; includes logs, chunks, bark, branches, stumps, and broken understory trees or brush.


5) Horizontal movement of air relative to the surface of the earth.


6) Fire burning without flame and barely spreading.


7) Rear portion of a wildland fire. Synonymous with Rear.


8) Manipulation of fuel prior to an incident to prevent the occurrence or slow the spread of wildland fire. Synonymous with Vegetation Management or Weed Abatement.


9) Aluminized device on a rod designed to be unrolled to reflect radiant heat from operators or crew members on some apparatus, bulldozers, or tractor-plows.


10) Flammable and combustible substances available for a wildland fire to consume.


11) Any obstruction of the spread of fire; typically an area or strip devoid of combustible fuel.


12) Fire burning with a low flame height and spreading slowly.


13) Rear portion of a wildland fire. Synonymous with Heel.


14) Process of thermodynamic change of state in which no heat is added or subtracted from a system; compression always results in warming, expansion results in cooling.


15) Precipitation that evaporates before reaching the ground.


16) Winds that are generated over a comparatively small area by local terrain and weather. They differ from those that would be appropriate to the general pressure pattern or that possess some other peculiarity.


17) Period(s) of the year during which fires are likely to occur, spread, and damage wildland values sufficient to warrant organized fire suppression.


18) Ordinary combustible solids such as wood, grass, rubber, cloth, paper, and plastics.


19) Landscaped and perhaps irrigated fuel break that is regularly maintained; sometimes put to an additional use (for example, golf course, park, playground, pasture). May also be dedicated but unmaintained open space within or between developments.


20) Uncontained and uncontrolled fire of intentional or accidental origin that may cause injury or damage.


21) Condition of the atmosphere in which the temperature decrease with increasing altitude is less than the dry adiabatic lapse rate. In this condition, the atmosphere tends to suppress large-scale vertical motion.


22) Point of original ignition of a fire. Synonymous with Point of Origin.
