SOP 207.01 FIREGROUND FACTORS
Fireground factors offer a standard list of
basic items Command must consider in the evaluation of tactical
situations. This list should provide
Command with a "checklist" of the basic items that are involved in
size-up, decision-making, initiating action, review and revision on the
fireground.
The effective Command officer soon learns
that he can only deal with a limited number of factors of any kind on the
fireground. Within the framework of that
1imitation, the identification of the critical factors is extremely
important. All the factors are not
critical in any one tactical situation.
Command must identify the critical fireground factors that are present
in each tactical situation, the list of factors offers a framework for that
process.
Many times we begin operations before
adequately considering the critical fireground factors. Size-up is a conscious process
involving the very rapid but deliberate consideration of the critical factors
and the development of a rational plan of attack based on those
conditions. Attack is many times an
instinctive action-oriented process that involves taking the shortest and
quickest route directly to the fire.
Action feels good in fireground situations while thinking delays action;
and beware of non- thinking attack situations and non-thinking attackers.
Fireground factors represent an array of
items that are dynamic during the entire fireground process and the relative
importance of each factor necessarily changes throughout that time frame.
Command must continually deal with these changes and base decisions on factor
information that is timely and current.
Beware of developing an initial plan of attack and sticking to that same
initial plan throughout the fire, even though conditions continue to
change. Effective fire operations
require attack plan revisions that continually reconsider fireground factors
based upon information feedback.
In critical fire situations, Command may develop an
initial plan and initiate an attack based on an incomplete evaluation of
fireground factors. In such cases,
he must continue throughout the operation to improve the information he bases his decisions upon. He will
seldom operate with complete information during initial operations.
The effective management of each fireground
factor requires Command to apply a somewhat different form of information
management (visual, recon, preplan) to that factor. This is particularly true between the major
categories of factors. Command must link
the best way to deal with each factor to that factor.
Most tactical situations represent a complex
problem with regard to how Command deals with fireground factor
information. There are factors that can
be determined from his operating position on the outside of the structure and
other factors that can only be determined from other operating positions for
both outside and inside the structure. Fireground intelligence available to Command
is developed utilizing an overlapping variety of these information factors
and forms.
These forms of information
revolve around the three following basic factors:
Size
Interior arrangement/access (stairs, halls,
elevators) Construction type
Age
Condition - faults/weaknesses
Value
Compartmentation/separation
Vertical-horizontal openings, shafts, channels
Outside openings - doors and windows/degree of
security Utility characteristics (hazards/controls).
Concealed spaces/attic characteristics
Exterior access
Effect the fire has had on the structure (at this
point).
Time projection on continuing fire effect on
building
Size
Extent (%
of structure involved)
Location
Stage (inception to flashover).
Direction of travel (most dangerous)
Time of involvement
Type of amount of material involved –
structure/interior finish/contents/everything
Type and amount of material left to burn
Product of combustion liberation.
Specific occupancy
Type-group (business, mercantile, public assembly,
institutional, residential, hazardous, industrial, storage, school)
Value characteristics associated with occupancy
Fire load (size,-nature)
Status (open, closed, occupied, vacant,
abandoned, under construction)
Occupancy associated characteristics/hazards
Type of contents (based on occupancy)
Time - as it affects occupancy use
Property conservation profile/susceptibility of
contents to damage/need for salvage
Moral hazard
Number of occupants
Location of occupants (in relation to the
fire)
Condition of occupants (by virtue of fire
exposure)
Incapacities of occupants
Commitment required for search and rescue (men,
equipment, and command)
Fire control required for search and rescue
Needs for EMS
Time estimate of fire effect on victims
Exposure of spectators/control of spectators
Hazards to fire personnel
Access rescue forces have to victims
Characteristics
of escape routes/avenues of escape (type, safety, fire conditions, etc.)
Access, arrangement, and distance of external
exposure
Combustibility of exposures
Access, arrangement, and nature of internal
exposures
Severity and urgency of exposures (fire
effect)
Value of exposures
Most dangerous direction - avenue of spread
Time estimate of fire effect on exposures (internal
and external)
Obstructions to operations
Capability/limitations on apparatus movement and use
Manpower and equipment on scene
Manpower and equipment responding
Manpower and equipment available in reserve
Estimate of response time for men and equipment
Condition of men and equipment
Capability and willingness of personnel
Capability of commanders
Nature of command systems available to Command
Number and location of hydrants
Supplemental water sources
Adequacy of water supply
Built-in private fire protection (sprinkler,
standpipe, alarms Outside agency resource and response time)
Time of day/night
Day of week
Season
Special hazards by virtue of holidays and special
events
Weather (wind, rain, heat, cold, humid,
visibility)
Traffic conditions
Social conditions (strike, riot, mob, rock festival)
