flaming front burning out of larger fuels (greater than about 3 inches in diameter). light

an advantageous location, usually a barrier to fire spread, from which to
start constructing a fireline. the anchor point is used to minimize the chance
anchor point of being flanked by the fire while the line is being constructed
near something that won't burn ex. road side mowed field
if no good anchor point, use a J hook
an inclusive term for all constructed or natural barriers and treated fire

fireline
soil
extinguishing or removing burning material near control lines, felling snags,
and trenching logs to prevent rolling after an area has burned, to make a
mop-up
fire safe, or to reduce residual smoke
switch from containing to putting out
no longer spreading
the status of a wildfire suppression action signifying that a
contained control line has been completed around the fire, and any
associated spot fires, which can reasonably be expected to stop the fire's
spread
