    statistics for 30 years—downward trend
5
   Fire Investigative Reports
• National Fire Protection Association
  (NFPA)
• National Institute for Occupational
  Safety and Health (NIOSH)
• U.S. Fire Administration (USFA)
5
           NFPA 1500 (1 of 5)
• Standard on Fire Department
  Occupational Safety and Health
  Program
• Can substantially reduce injury
  frequency and severity
  – Minimum safety measures
  – ICs and safety officers must be familiar
    with this standard.
5
            NFPA 1500 (2 of 5)
• Important fire-ground safety issues:
  – Risk management principles
  – IC responsible for overall safety
  – Incident management system must be
    used at all scenes

5
Fire-Ground Fatalities
5
     Increased Hazards (1 of 2)
• Lightweight construction
  – Truss roofs
5
     Increased Hazards (2 of 2)
• Heavy fuel loads
  – Large amounts of plastics
• Very large buildings
5
                Occupancy
•   Plays a role in fire fighter safety
•   No routine fires
•   Most fatalities occur in residential fires.
•   Risk increases twofold in a
    manufacturing setting.
5
     Single-Family Mindset
• Must be avoided
• Escape routes are closer and easier to
  find.
• SCBA depletion or failure
5
          On-Duty Deaths
• Leading causes:
  – Sudden cardiac death
    • Preventable
  – Asphyxiation
  – Crushing injuries and burns
5
            Responsibility
• Administration
• Procedures
  – Training
  – Equipment
• ICs have overall safety responsibility.
  – Must monitor, organize, coordinate, and
    provide adequate safety measures
5
    Personal Responsibility
• Fire fighters must take personal
  responsibility through:
  – Following procedures
  – Maintaining firefighting skills
  – Proper use of equipment
5
        Risk Management
• Most important element
• NFPA 1500
  – Risk management principles
  – Must be applied to every situation
• IC weighs risk against possible benefits.
5
      Two-in, Two-out Rule
• Exception:
  – Imminent life-threatening situation
  – Definition is not completely understood
• IC expected to exercise judgment
5
              Probability
• Important concept to risk management
  and size-up processes
  – People being in the building considered as
    a degree of probability
  – Determining factors: time of day, day of
    week, time of year
• Primary search is the only sure way of
  knowing.
5
             Fire Intensity
• Important in determining what there is to
  save.
• Hazards increase as fire progresses
  towards flashover.
  – Building is getting weaker
  – Flashover is unpredictable.
5
           Flashover (1 of 2)
• Time to flashover depends on:
  – Compartment size
  – Ventilation
  – Ignition source
  – Fuel supply
  – Fuel geometry
5
            Flashover (2 of 2)
• Time to flashover depends on
  (continued):
  – Distance between fuel cells
  – Location of the fuel
  – Heat capacity of the fuel
  – Geometry of the enclosure
5
      Building Design Loads
• Loads imposed on buildings:
  – Live loads
  – Dead loads
  – Seismic, wind, snow, and ice loads
• Affect structural stability
  – High loads can result in premature
    collapse.
  – Loads placed on lightweight roof structures
5
                  Fuel Load
• Consists of fuels provided by:
  – Contents
     • Primary fuel load in structure fires
  – Combustible building materials
     • Wood frame construction
5
      Structural Stability (1 of 4)
• IC/safety officer must watch for signs of
  structural failure
• Should be considered in size up
  – Failure can occur at any time.
• Must understand collapse dynamics
5
      Structural Stability (2 of 4)
• IC must take into account when:
  – Deciding on strategy
  – Placing companies
• Cannot be reliably predicted
  – No building is immune.
  – Some withstand a large fire without
    collapse.
  – Others experience early collapse.
5
      Structural Stability (3 of 4)
• Stability affected by:
  – Fire intensity
  – Burn time
  – Content loads
  – Construction methods and materials
5
      Structural Stability (4 of 4)
• 20-minute rule
  – Ordinary construction
  – Structural collapse anticipated:
     • Heavy volume of fire
     • Two or more floors
     • 20 minutes or longer
5
         Time and Intensity
• Is it safe to enter?
  – IC should “start the clock.”
  – If fire is still not under control:
     • IAP should be reviewed.
     • Operation possibly changed to defensive
5
          Managed Retreat
• When changing from offensive to defensive
  – Engine companies provide protection.
• If collapse is imminent, the offensive
  operation should be abandoned immediately.
• All units notified by:
  – Radio announcement
  – Pre-planned signal
5
   Construction Materials (1 of 2)
• Wide variety in use
  – Behavior of buildings will vary significantly.
  – Lighter weight structural members
     • Provide same load-bearing capabilities
     • Truss construction takes the place of large
       wood beams or steel I-beams
     • Structurally sound under normal conditions
5
   Construction Materials (2 of 2)
• Lightweight members are affected by
  fire sooner.
  – Trusses lose load-bearing capacity once
    they lose their triangular configuration.
  – Failure with little warning
5
   Structural Connections (1 of 2)
• Play a critical role in a building fire
  – Gusset plates used in place of nails
     • Nails form a stronger connection.
  – Penetrate only a fraction of an inch
  – Form a large surface area to collect heat
5
   Structural Connections (2 of 2)
• Wood truss loses its stability as:
  – Gusset plate teeth lose strength
  – Fire burns through the wood connecting
    surfaces
5
Gusset Plate Failure
5
              Fire Spread
• Can occur through variety of openings
  – Horizontal: joist/truss spaces
  – Vertical: utility shafts
• Renovations affect fire spread:
  openings in floors not always properly
  sealed
5
          Roof Operations
• Conscious decision regarding roof
  safety
  – Lightweight truss roofs are dangerous.
• Risk-versus-benefit decision
  – Must be made before placing fire fighters
    on or under roof
5
     Pre-Fire Conditions (1 of 5)
• Factors for evaluating collapse potential
  of a building:
  – Weight                – Renovations
  – Fuel loads            – Deterioration
  – Damage                – Support systems
  – Truss construction
5
     Pre-Fire Conditions (2 of 5)
• Weight, live and dead loads including:
  – Air conditioning units
  – Tanks containing liquids
  – Large signs and marquees
  – False fronts (façades)
  – Cantilever appendages
  – Heavy machinery
5
     Pre-Fire Conditions (3 of 5)
• Fuel loads
  – Type, location, and arrangement fuel loads
• Damage structural support system
  – Previous fires, weather or collapse
5
     Pre-Fire Conditions (4 of 5)
• Renovations
  – Older buildings
• Deterioration
  – Buildings or areas in poor repair
  – Vacant buildings
5
     Pre-Fire Conditions (5 of 5)
• Support systems
  – Long spans (churches, warehouses)
• Truss construction
  – Identified through pre-planning
5
           Fire Conditions
• Sometimes difficult to read
• Failures occur without warning.
• Must recognize signs of imminent
  collapse
  – Maintain span of control
• Time and fire intensity are major factors.
5
Signs of Structural Collapse (1 of 2)
•   Bulging, cracked, or unsupported walls
•   Walls leaking water or smoke
•   Falling bricks
•   Floors holding large volumes of water or
    stock soaked with water
5
Signs of Structural Collapse (2 of 2)
• Movement in floors or roof
• Other signs of structural movement,
  including unusual noises
• Vertical structural members that are out
  of plumb (columns, walls, etc.)
5
             Fire Extension
• Some buildings limit fire spread better
  than others.
• Concealed spaces
  – Fire can extend to remote locations
     • Results in a sudden increase in heat intensity
     • Can break out at multiple locations
5
     Concealed Spaces (1 of 2)
• Fire fighters without a hose line are at
  high risk.
• Fire extension can cut off primary
  means of egress.
• Proper venting will direct fire.
• Improper venting pulls fire.
5
     Concealed Spaces (2 of 2)
• Fires in concealed ceiling areas can get
  behind fire fighters.
  – Hose streams can accelerate movement of
    fire.
• Must be checked
  – Thermal imaging cameras
  – Opened up with tools
5
         Truss Assemblies
• Floor assemblies
  – Used to reduce construction costs
  – Creates concealed space
  – Less fire-resistive than heavier, solid beam
    construction
• Have played a major role in fire fighter
  fatalities
5
Truss Floor Assembly
5
  Non-Combustible Buildings
• Mistaken for fire-resistive
  – Modern, big-box retail stores
  – May be masonry or metal on the exterior
  – Lightweight metal truss roof structure
• Large open areas with long spans
  – Expect imminent roof collapse if fire enters
    spaces.
5
 Automatic Sprinkler Systems
• Usually control fires
  – Consider code variances or “trade-ups”
  – If system is not controlling fire, consider
    hazards in entering large-span truss space
    with heavy fire load.
5
  Fire Zones and Perimeters
• Establish collapse zone
• Collapse indicated by:
  – Construction features
  – Fire factors
• Cannot accurately predict:
  – Type of collapse
  – Collapse zone
5
          Exclusion Zones
• Collapse zones = exclusion zones
  – No one permitted to enter
  – Can exist in buildings (suspect roof
    structures)
  – Other areas:
    • Falling glass
    • Flammable/combustible atmospheres
5
              Cold Zone
• PPE is not required.
• Location of command post
  – Staff and command functions
• Includes rehab and medical areas
5
              Hot Zone
• Safe only when wearing appropriate
  PPE
• Established and enforced by IC and
  safety officer; everyone must abide by
  their decision.
5
             Warm Zone
• Not always necessary during a structure
  fire
• Established as an intermediate zone
  – Between hot and cold zones
  – When different levels of PPE are needed
    for various areas
5
      Accountability System
• Must be established on the fire-ground:
  – Ensures everyone entering the area has a
    specific assignment
     • Eliminates freelancing
  – Tracks all personnel
     • Identifies the location of any missing personnel
5
Time, Fire Intensity, and
   Structural Stability
5

   Time: Ignition to Effective
            Actions
• Goal: To arrive prior to flashover and
  intervene
  – Interrupts fire’s progression
  – Progression in small enclosures can be
    fast.
     • May occur prior to the arrival
     • Objective is to contain the fire
5
          Analyzing Time
• It is necessary to consider the following
  five components:
  – Pre-burn time
  – Dispatch time
  – Turnout time
  – Response time
  – Set-up time
5
Detection/Transmission Time
• Pre-burn time
  – Time from ignition until fire is reported
     • Will vary greatly
     • Is unknown until the alarm occurs
  – Dependent upon discovery and reporting
     • Unless equipped with a detection/alarm system
  – Can be estimated based on experience
5
           Dispatch Time
• NFPA 1221: Installation, Maintenance,
  and Use of Emergency Services
  Communications Systems sets time
  goals for dispatch centers.
• Includes time for the dispatcher to:
  – Take the call
  – Select units for the assignment
  – Dispatch companies
5
            Turnout Time
• Time from alarm receipt until apparatus
  leaves station
• Can differ greatly between fully staffed
  stations and on-call stations
5
            NFPA 1710
• Standard for the Organization and
  Deployment of Fire Suppression
  Operations, Emergency Medical
  Operations, and Special Operations to
  the Public by Career Fire Departments
  defines turnout time
• Time beginning when units
  acknowledge notification to beginning
  point of response time
• Time objective = one minute
5
            NFPA 1720
• Standard for the Organization and
  Deployment of Fire Suppression
  Operations, Emergency Medical
  Operations, and Special Operations to
  the Public by Volunteer Fire
  Departments does not address turnout
  time.
5
          Response Time
• Dependant on road conditions, terrain,
  distance, traffic, and other factors
• Averages can be established using
  computer models.
5
              NFPA 1710
• NFPA 1710 establishes two response
  time goals:
  – Four minutes (240 seconds) or less for
    arrival of the first engine company
  – Eight minutes (480 seconds) or less for the
    deployment of a full first alarm assignment
  – No less than 90 percent within time goal
5
          Response Safety
• Many fire fighters are killed or injured
  while responding to incidents.
  – Response/travel time improvements
     • Realized by reducing distance from fire station
       to response area
     • Not by increasing speed of apparatus or
       ignoring negative right-of-way situations
5
              Set-Up Time
• Time necessary to position apparatus,
  advance hose line and apply water
• Affected by staffing levels and training
  – Two-in/two-out rule changes setup time
     • Four people must be on the scene.
     • Two must be positioned outside the hazard
       area.
5
              NFPA 1410
• Standard on Training for Initial
  Emergency Scene Operations sets
  training goals.
  – 3 to 6 minutes to establish water supply
    and discharge water
  – Improvement through training
5
      Initial Response Only
• Times are valid for initial response only
  – Less dispatch time when units are on-
    scene, calling for help.
  – Reduce for subsequent calls by:
     • Placing units on alert status
     • Moving into vacated stations
     • Placing units in staging areas
  – Set-up time will change depending on task
    assignment
5

       Adequate Number of
           Personnel
• Set-up time is related to staffing.
  – Initial attack should be delayed if:
     • Company staffing is less than four
     • Imminent life-threatening situation does not
       exist
5
              NFPA 1500
• Stipulates a minimum of four fire
  fighters as an initial crew at a working
  structure fire
  – Unless imminent life-threatening situation
    exists
  – Three is acceptable in situations of
    imminent danger
5
     Fire-Ground Tasks (1 of 3)
• Required to save lives and protect
  property
• Additional attack lines
• Attack line above the fire
• Attack line to concealed spaces
• Backup for the initial attack line
5
       Fire-Ground Tasks (2 of 3)
•   Exposure protection
•   Forcing entry
•   Laddering the building
•   Opening up concealed spaces
•   Salvage or property conservation
5
     Fire-Ground Tasks (3 of 3)
• Search and rescue of area around the
  fire
• Search and rescue of area above the
  fire
• Search and rescue of other areas
• Utility control
• Ventilation
5
                NFPA 1710
• Establishes minimum staffing levels
  – Tasks to be accomplished
  – Personnel needed
  – Minimum of 14 personnel
     • 15 if an aerial device is used
5
         Tactical Reserve
• Planning is crucial.
• Tactical efficiency can reduce number
  of people necessary.
• Size of tactical reserve force depends
  on:
  – Stage and type of incident
  – Number of units working
5
 Elapsed Time and Flashover
• Time is a critical factor.
• Longer the fire burns:
  – Less chance for rescue
  – Greater chance of structural collapse
  – Post-flashover chance for survival = near
    zero
  – Risk to fire fighters increases
5
         Communications
• Lifeblood of any command organization
• Situation could be chaotic without
  communications.
  – Each crew should have a radio.
5
          Radio Discipline
• Significant challenge
• Imperative when everyone is assigned a
  radio
  – Proper use of the radio
    • Clear
    • Calm
    • Concise
5
         Progress Reports
• Essential to the IC
• Interior crews = eyes and ears of the IC
• Provide information to everyone on fire-
  ground
5
     Emergency Operations
• Mayday is used to indicate that a fire
  fighter is in trouble.
• SOPs should define response to a
  Mayday
  – Critical functions will not be accomplished
    if all personnel begin focusing on the
    rescue operation.
5
              Mayday
• IC must remain in total control.
• Officers must remain within the ICS.
• Specific assignments should be made
  for the rescue operation.
5
        Evacuation Signal
• Should be established through SOPs
  – 10 three-second blasts of air horns
  – Emergency evacuation radio message
5
              Evacuation
• “Drop everything and run”
  – Seldom warranted
  – Used during defensive operations
• Offensive operations
  – Organized retreat is better alternative
5
     Command and Control
• Common goal
  – Organized fashion
  – Safe and effective operation
• Freelancing leads to injuries and
  fatalities.
5
             Accountability
• A good organizational structure:
  – Accounts for all personnel at scene
  – Maintains reasonable span of control
     • Crew unity is essential.
• Crew members should not be separated
  within the structure.
5

    Personnel Accountability
          Report (1 of 2)
• Often referred to as a PAR.
• SOPs call for PARs in the following
  situations when:
  – IC thinks it is necessary
  – Safety officer requests one
  – IC changes from an offensive to a
    defensive attack
5

      Personnel Accountability
            Report (2 of 2)
•   Sudden changes occur.
•   Entire building has been searched.
•   Fire is extinguished.
•   Called for at prescribed times
    – NFPA 1500: Every 10 minutes
5
   Accountability Procedures
• More important as incident increases in
  size and complexity
  – Mutual aid resources
  – A regional approach is logical
5
      Accountability Officer
• Should not be the safety officer
  – Safety officer is mobile.
  – Accountability officer is stationary.
• The accountability officer is an
  informational resource for the safety
  officer, RIC, and IC.
5
            Safety Officer
• Safety is everyone’s responsibility.
  – Whether or not a safety officer has been
    assigned
• Safety officer monitors all areas.
• SOPs outline when position is
  established
  – When IC can no longer effectively monitor
    safety at the scene
5
      Alternative Egress (1 of 2)
• Interior stairs
  – Preferred means of access and egress
• Fire escapes
  – Additional means
  – Provide access to upper floors
5
     Alternative Egress (2 of 2)
• Proper laddering
  – Should be accomplished early in operation
• Provides alternative means of egress
• Addressed in SOPs
• Location of ladders must be
  communicated to crews.
5
    Rapid Intervention Crews
• Staffing is not sufficient until:
  – Safety and tactical positions are covered
  – Tactical reserve is available.
• Critical need to provide rescuers for fire
  crews
  – RIC: no substitute for safe and effective
    operations
5
       Fire Fighter Rescue
• IAP will reduce the need for emergency
  rescues.
  – Risk-versus-benefit analysis
  – Good tactics
  – Company-level attention to safety
5
    Safe Interior Operations (1 of 2)
•   Maintain crew integrity
•   Provide hose line protection
•   Provide means of communications
•   Maintain contact with the hose line
5
  Safe Interior Operations (2 of 2)
• Maintain contact with a wall or rope
• Indicate door leading to where fire
  fighters are working
• Learn self-survival techniques
5
                  RIC Officer
• Determines need for special tools
  – Based on:
     •   Construction type
     •   Occupancy
     •   Fire location
     •   Other factors
  – Could be identified through pre-planning

  • 45.
    5 Managed Retreat • When changing from offensive to defensive – Engine companies provide protection. • If collapse is imminent, the offensive operation should be abandoned immediately. • All units notified by: – Radio announcement – Pre-planned signal
  • 46.
    5 Construction Materials (1 of 2) • Wide variety in use – Behavior of buildings will vary significantly. – Lighter weight structural members • Provide same load-bearing capabilities • Truss construction takes the place of large wood beams or steel I-beams • Structurally sound under normal conditions
  • 47.
    5 Construction Materials (2 of 2) • Lightweight members are affected by fire sooner. – Trusses lose load-bearing capacity once they lose their triangular configuration. – Failure with little warning
  • 48.
    5 Structural Connections (1 of 2) • Play a critical role in a building fire – Gusset plates used in place of nails • Nails form a stronger connection. – Penetrate only a fraction of an inch – Form a large surface area to collect heat
  • 49.
    5 Structural Connections (2 of 2) • Wood truss loses its stability as: – Gusset plate teeth lose strength – Fire burns through the wood connecting surfaces
  • 50.
  • 51.

  • 84.
    5 Response Safety • Many fire fighters are killed or injured while responding to incidents. – Response/travel time improvements • Realized by reducing distance from fire station to response area • Not by increasing speed of apparatus or ignoring negative right-of-way situations
  • 85.
    5 Set-Up Time • Time necessary to position apparatus, advance hose line and apply water • Affected by staffing levels and training – Two-in/two-out rule changes setup time • Four people must be on the scene. • Two must be positioned outside the hazard area.
  • 86.
    5 NFPA 1410 • Standard on Training for Initial Emergency Scene Operations sets training goals. – 3 to 6 minutes to establish water supply and discharge water – Improvement through training
  • 87.
    5 Initial Response Only • Times are valid for initial response only – Less dispatch time when units are on- scene, calling for help. – Reduce for subsequent calls by: • Placing units on alert status • Moving into vacated stations • Placing units in staging areas – Set-up time will change depending on task assignment
  • 88.
    5 Adequate Number of Personnel • Set-up time is related to staffing. – Initial attack should be delayed if: • Company staffing is less than four • Imminent life-threatening situation does not exist
  • 89.

  • 100.
    5 Mayday • IC must remain in total control. • Officers must remain within the ICS. • Specific assignments should be made for the rescue operation.
  • 101.
    5 Evacuation Signal • Should be established through SOPs – 10 three-second blasts of air horns – Emergency evacuation radio message
  • 102.
    5 Evacuation • “Drop everything and run” – Seldom warranted – Used during defensive operations • Offensive operations – Organized retreat is better alternative
  • 103.
    5 Command and Control • Common goal – Organized fashion – Safe and effective operation • Freelancing leads to injuries and fatalities.
  • 104.
    5 Accountability • A good organizational structure: – Accounts for all personnel at scene – Maintains reasonable span of control • Crew unity is essential. • Crew members should not be separated within the structure.
  • 105.
    5 Personnel Accountability Report (1 of 2) • Often referred to as a PAR. • SOPs call for PARs in the following situations when: – IC thinks it is necessary – Safety officer requests one – IC changes from an offensive to a defensive attack
