Editing The Burning Line (section)

==D==
*'''Dead Man Zone''': Unburnt areas around edges of brush fire.
*'''Demob''': Demobilization, or a crew being removed from working a fire.
*'''Direct Attack''': Any treatment applied directly to burning fuel such as wetting, smothering, or chemically quenching the fire or by physically separating the burning from unburned fuel.
*'''Dozer line''': Fireline constructed by the front blade of a [[bulldozer]] or any tracked vehicle with a front mounted blade used for exposing mineral soil.  Also "catline."
*'''Draft (water)|Drafting''': using a suction pump to lift water from below the pump, using a semi-rigid suction hose, typically to fill a portable reservoir that has other suction pumps (to relay) or siphon hoses running downhill to their nozzles. 
*'''Driptorch|Drip torch''': hand-carried fire-starting device filled with flammable liquid that is poured across a flaming wick, dropping flaming liquid onto the fuels to be burned.
*'''Duff''': Layer of decaying forest litter consisting of organics such as needles, leaves, plant and tree materials covering the mineral soil.  Duff can smolder for days after a fire.  Extinguishing smoldering duff is key to successful mopup operations.
