Definition:
Backfire: A fire set along the inner edge of a fireline to consume the fuel in the path of a wildfire 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.
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 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.
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.
