Terms and Definitions

Backfire
A fire set along the inner edge of a fireline to consume the fuel in the path of a wildland fire and/or change the direction of force of the fire's convection column.
|
|
|
Backpack Pump
A portable sprayer with hand-pump, fed from a liquid-filled container fitted with straps, used mainly in fire and pest control.

|
Bambi Bucket
A collapsible bucket slung below a helicopter. Used to dip water from a variety of sources for fire suppression.
|
|
|
Behave
A system of interactive computer programs for modeling fuel and fire behavior that consists of two systems: BURN and FUEL.
|
|
|
Blackline
Refers to fuels that have burned, either intentionally or not. Many prescribed fire and wildland fire suppression techniques are based on the concept of blackline as a barrier to fire spread.
|
|
|
Bladder Bag
A collapsible backpack portable sprayer made of neoprene or high-strength nylon fabric fitted with a pump.

Blow-up
A sudden increase in fire intensity or rate of spread strong enough to prevent direct control or to upset control plans. Blow-ups are often accompanied by violent convection and may have other characteristics of a fire storm.

|
Brush
A collective term that refers to stands of vegetation dominated by shrubby, woody plants, or low growing trees, usually of a type undesirable for livestock or timber management.
|

Brush Fire
A fire burning in vegetation that is predominantly shrubs, brush and scrub growth.
|
|
|
Bucket Drops
The dropping of fire retardants or suppressants from specially designed buckets slung below a helicopter.
|
|
|
Buffer Zones
An area of reduced vegetation that separates wildlands from vulnerable residential or business developments. This barrier is similar to a greenbelt in that it is usually used for another purpose such as agriculture, recreation areas, parks or golf courses.
|
|
|
Bump-up Method
A progressive method of building a fire line on a wildland fire without changing relative positions in the line. Work is begun with a suitable space between workers. Whenever one worker overtakes another, all workers ahead move one space forward and resume work on the uncompleted part of the line. The last worker does not move ahead until completing his or her space.
|
|
|
Burn Out
Setting fire inside a control line to widen it or consume fuel between the edge of the fire and the control line.
|
|
|
Burning Ban
A declared ban on open air burning within a specified area, usually due to sustained high fire danger.
|
|
|
Burning Conditions
The state of the combined factors of the environment that affect fire behavior in a specified fuel type.
|
|
|
Burning Index
An estimate of the potential difficulty of fire containment as it relates to the flame length at the most rapidly spreading portion of a fire’s perimeter.
|
|
|
Burning Period
That part of each 24-hour period when fires spread most rapidly, typically from 10:00 a.m. to sundown.
