Wildland Incidents Flashcards
The point of origin of the fire. This area burns at an intensity that is less than the rest of the fire and has a slower rate of spread
Heel
Narrow strips of fire extending out word from the main fire
Fingers
The area of the fire where the burning is fastest and hottest
Head
Spot support areas along the fire perimeter that burn more vigorously than the surrounding area
Hot spots
Fires that ignite outside the main fire perimeter; Usually started by hot embers blown from the main fire
Spot fires
The area burned as defined inside the fire perimeter
Burn
The area unburned outside the fire perimeter
Green
An area within the burn or fire parameter that has not been burned
Island
An area of unburned fuel located between two fingers or between the fire perimeter and a finger
The ignition of a number of fires with in an area simultaneously or in quick succession
Area ignition
A sudden increase in fire intensity or rate of spread that precludes direct control or upsets existing control measures
Blow up
The number expressed in an arithmetic scale that is determined from the fuel moisture content, windspeed, and other selected factors affecting burning rates.
Burn index
The ignition of unburned fuels within the fire line or perimeter as part of the direct for parallel method of fire control
Burning out
The intentional setting of fire to fuels inside the control line to slow, knockdown, or contain a rapidly spreading fire.
Backfire
This is a method of controlling a partly dead fire by carefully inspecting and feeling with their hands while building a fire line around and digging out every live spot
Cold trailing
This is a fire that advances from top to top of trees or shrubs and is independent of the surface fire
Crown fire
Suppression efforts on the fires edge or immediately adjacent to the fire perimeter
Direct attack
A fire control management system that integrates the effects of selected fire danger factors into one or more qualitative or numerical indicators of the current level of fire protection needed
Fire danger rating
A spinning, moving column of ascending there, which arises from a vortex and may carry a loft smoke, debris, and flames ranging in size and intensity from 1 foot in diameter to a small tornado
Fire whirl
This is a dry wind with strong downward components that moves from a high-pressure area to a low pressure area
Foehn
The checking of the spread of fire at points of more rapid spread or special threat areas with emphasis on first priorities, usually in the initial steps of the immediate control.
Hot spotting
This is the construction of a line in the”Green” or unburned fuel at a considerable distance from the fire line that can be used for different operations
Indirect attack
Initiate an anger point near the point of origin to attack two sides of the fire to cut off the head.
Pincer attack
And unfinished preliminary control line established or constructed as an emergency measure to check the spread of fire
Scratch line
