SOP 207.04 FIRE CONTROL
It is standard operating procedure to attempt to
stabilize fire conditions by extending WHEREVER POSSIBLE an aggressive
well placed and adequate offensive interior fire attack effort and to support
that aggressive attack with whatever resource and action is required to reduce
fire extension and to bring the fire under control.
A critical Command decision (both
initial and on-going) relates to
the offensive/defensive mode of the situation:
Offensive Strategy - Interior attack and related support
directed toward quickly bringing the fire under control.
Defensive Strategy - Exterior attack directed to first
reduce fire extension and then bring the fire under control.
Command must define offensive/defensive
mode based upon:
Fire extent
Structural conditions
Entry capability
Ventilation profile
Rescue ability of occupants Resources
BASIC OFFENSIVE-PLAN:
Take Command
First
line - fast, aggressive interior attack
Provide
support activities
Do primary search
Second line - back up first/cover rear
Pump water
Quickly evaluate success and react
BASIC DEFENSIVE-PLAN:
Take Command
Evaluate fire spread/write-off lost property
Identify key tactical positions
Prioritize fire streams
Provide big, well placed streams
Pump water
Quick.-determination on additional resources
Surround and drown
Many times offensive/defensive conditions are
clear cut and Command can quickly develop a. decision that relates to that
mode. In other cases, the situation is
marginal and Command must initiate an offensive interior attack, while setting
up defensive positions on the exterior.
The effect of the interior attack must be evaluated and the attack
abandoned if necessary. Mode changes
can develop almost instantly or can take virtually all night; Command must be
aware and responsive to such mode changes.
Command must
consider the most dangerous direction and avenues of fire extension
particularly as it affects rescue activities, confinement efforts, and exposure
protection. He must then allocate
resource based upon this fire spread evaluation.
In some cases, the most
effective tactical analysis involves an evaluation of what is not burning
rather than what is actually on fire.
The unburned portion represents where the fire is going and should
establish the framework for fire control requirements.
Offensive fires should be
fought from the INTERIOR-UNBURNED SIDE (interior capability is the principal
offensive strategy factor)
Initial attack efforts must be directed toward supporting primary search - first attack must go between the victims and the fire and protect avenues of escape.
Determine fire location and extent before
starting fire operations (as far as possible). Do not operate fire streams into smoke.
Command cannot lose sight of the very simple
and basic fireground reality that. at some point the fire forces must engage the
fire and fight. Command must structure
whatever operations are required to PUT WATER ON THE FIRE. The. rescue/fire control/extension/exposure
problem is solved in the majority of cases by a fast, strong, well-placed
attack.
Effective fire control requires that water is
applied directly on the fire or directly into the fire area .(Fire
streams can be bounced off. roofs and operated into smoke all night and the
fire will progress until it runs out of fuel.) Command must establish
an attack plan that overpowers the fire with actual water application .
Where fires involve concealed spaces (attics,
ceiling areas, construction voids, etc.) it becomes very important that
ladder companies open-up and engine companies operate fire streams into such
areas .Early identification and response to concealed-space fires can save the
structure. Officers who hesitate to
open up because they don't want to beat up the building many times must attempt
an hour later to hold the fire to the neighborhood of origin.
Command must consider 7
sides (or sectors) of the f ire: front, back, sides , top,
bottom, and interior.
Where the fire is sizeable, establish a safe
and remote position to begin operations from, then move in on the fire.
The basic variables relating
-to attack operations involve:
Location/position of attack Size of attack
Support functions
Command develops an effective attack through
the management of these factors .
Time becomes an extremely important factor
with regard to attack operations. The bigger
the attack, the longer it takes to get it going; the more interior the attack
is positioned, the longer it takes .Command must balance and integrate attack
size and position with fire conditions and his resources.
Tactical realities many times require that
pure placement principles are violated.
Such violations generally relate to the factor of time vs. pure
placement. . When such principles are violated, Command must implement back-up
action to cover the "uncovered" area(s).
Lacking direction, when fire is showing, companies will many times lay hose and put water on the fire utilizing the fastest, shortest, most direct route. This process is called the "candle moth" syndrome - everyone wants to go to the flame.
Attack from the burned side generally will
drive the fire, smoke and heat back into the building and the interior fire
control forces out of the building.
The fastest place to put water on the fire is
generally from the outside at the point
where the fire is burning out of the building - the very worst application
point most of the time.
When fire is burning out of a building and
not affecting exposures, let it burn out and extend an interior attack from the
unburned side. It is usually venting in
the proper direction. It requires
discipline on the part of control forces to do so and not submit to
"candle moth " temptations.
Command must develop a fire control plan of
attack that first stops the forward progress of the fire and then brings the
fire under control. In large complex
fires, Command will not immediately have adequate resources to accomplish all
of the attack needs he faces - at that point, he must prioritize attack
efforts, act as a resource allocator and determine the response he will
eventually require. Accurate
forecasting of conditions by Command becomes critical during this initial
evaluation process.
Command must develop critical decisions that
relate to cut-off points and must approach fire spread determinations with
pessimism. It takes a certain amount of time to "get water" and the
fire continues to burn while the attack gets set up. Command must consider where the fire will be
when attack efforts are ready to actually go into operation; if he misjudges,
the fire may burn past his attack/cut-off position: Don't play "catch up" with a
fire that is burning through a building:
Project your set-up time
Write-off lost property
Get ahead of the fire
Set up adequately- and overpower it.
Don't put water into burned property,
particularly where there is unburned property left to burn. Many fire streams are directed into property
that-is already lost, many times at the expense of exposed unburned property. Write-off property that is already lost
and go on to protect exposed property based on the most dangerous direction of
spread. Do not continue to operate in
positions that are essentially lost.
DEFENSIVE MODE OPERATIONS
The decision to operate in a defensive mode indicates
that the offensive attack strategy has been abandoned for reasons of personnel
safety, and the involved structure has been conceded as lost (written
off).
The announcement of a change to a defensive mode will be made as Emergency Traffic and all personnel will withdraw from the structure and maintain a safe perimeter. Staff Officers will account for the safety of all personnel.
Interior lines will be withdrawn (or abandoned
if necessary) and repositioned when changing to a defensive mode. Lines
should not be operated directly into doorways or windows but should be backed
away to positions that will protect exposures.
All exposures, both immediate and anticipated , must be identified and
covered. The first priority in
defensive operations is to protect exposures.
The second priority may be to' knock down the main body of fire. This may assist in the protection of exposures but does not replace it as a first priority .
Master streams are generally the most effective
tactic to be employed in defensive operations.
For tactical purposes, a standard master stream flow of 750 GPM
should be the guideline. Adjustments
may be made upward or downward from this figure but it is very significant in
the initial deployment of master streams.
When the exposure is severe and water is
limited, the most effective tactic is to put the water on the exposure.
Once exposure coverage is established, attention may be directed to knocking down the main body of fire and thermal-column cooling. The same principles of large volume procedures should be employed.
The completion of bringing the fire under
control is reported utilizing the standard radio reporting term: "FIRE UNDER CONTROL”. It is the
responsibility of Command to transmit this report to Alarm. This time will be
recorded by Dispatch.
Fire under control means the
forward progress of the fire has been stopped and the remaining fire can be
extinguished with the on-scene resources; it does not mean that the fire
is completely extinguished.
