Recognizing
Experienced Wildland Fire Supervisors
There
are many studies resulting in formulas that are applied to pre-determining
the fire behavior, should one start in forest fuels. These efforts
were made to assist forest managers who plan pre suppression actions
which are designed to better protect the values at risk. These formulae
and matrix models are developed for planning purposes and are not
exact predictors of fire behavior. Thus, these methods are not practical
for tactical applications and are not used by fire officers on the
fireline.
There
have not been many studies made of how experienced fire officers
predict the variances of fire behavior using visual observations
of the fire to determine its potential. "Drillground commanders"
stay engaged until they are run out while the expert officer pre-determines
actions from signs of danger and makes adjustments, before being
run out by the fire.
Before
checking off the L.C.E.S. list fireline supervisors need to determine
and explain the following:
- When
and where will the fire behavior be within their control capabilities,
to assure progress is made.
- How
the fire will behave throughout the shift, to properly plan the
tactical action.
(Fire Behavior Tactics)
- When
and where the potential fire behavior is beyond safe thresholds,
to pick proper safety areas and escape routes.
A "drillground commander" starts action without much
regard for the up coming changes that will occur during the shift.
Before
engaging in suppression action, a skilled and experienced officer
determines the answers to these questions using the information
gained from observations of the fire burning in the area. This is
the size-up of the situation.
To
become skilled and experienced takes a long time and a lot of exposure
to the dangers of firefighting. The Campbell Prediction System is
a course of study which uses specialized logic and language to describe
fireground observations. The logic and language enables students
to learn in hours what takes most firefighters years to learn. Reducing
the time firefighters engage fires while learning the art, is an
important safety advance.
