Definition:
Tactics: Deploying and directing resources on an incident to accomplish the objectives designated by strategy.
Test Fire: A small fire ignited within the planned burn unit to determine the characteristic of the prescribed fire, such as fire behavior, detection performance and control measures.
Timelag: Time needed under specified conditions for a fuel particle to lose about 63 percent of the difference between its initial moisture content and its equilibrium moisture content. If conditions remain unchanged, a fuel will reach 95 percent of its equilibrium moisture content after four timelag periods.
Torching: The ignition and flare-up of a tree or small group of trees, usually from bottom to top.
Type: The capability of a firefighting resource in comparison to another type. Type 1 usually means a greater capability due to power, size, or capacity.
Uncontrolled Fire: Any fire which threatens to destroy life, property, or natural resources.
Underburn: A fire that consumes surface fuels but not trees or shrubs. (See Surface Fuels.)
Vectors: Directions of fire spread as related to rate of spread calculations (in degrees from upslope).
Volunteer Fire Department (VFD): A fire department of which some or all members are unpaid.
