Definition:
Dead Fuels: Fuels with no living tissue in which moisture content is governed almost entirely by atmospheric moisture (relative humidity and precipitation), dry-bulb temperature, and solar radiation.
Debris Burning: A fire originally set for the purpose of clearing land or for rubbish, garbage, or pasture burning.
Direct Attack: Any treatment of burning fuel, such as by wetting, smothering, or chemically quenching the fire or by physically separating burning from unburned fuel.
Dispatch: The implementation of a command decision to move a resource or resources from one place to another.
Dispatch Center: A facility from which resources are directly assigned to an incident.
Dozer Line: Fire line constructed by the front blade of a dozer.
Drip Torch: Hand-held device for igniting fires by dripping flaming liquid fuel on the materials to be burned; consists of a fuel fount, burner arm, and igniter. Fuel used is generally a mixture of diesel and gasoline.
Drop Zone: Target area for air tankers, helitankers, and cargo dropping.
Drought Index: A number representing net effect of evaporation, transpiration, and precipitation in producing cumulative moisture depletion in deep duff or upper soil layers.
Dry Lightning Storm: Thunderstorm in which negligible precipitation reaches the ground. Also called a dry storm.
Duff: The layer of decomposing organic materials lying below the litter layer of freshly fallen twigs, needles, and leaves and immediately above the mineral soil.
