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
