ARFF11–5
Incident Management
• Airport fire departments — required to adopt and use an incident management system– Strategic operations– Tactical operations
(Continued)
ARFF11–6
Incident Management
• Homeland Security Presidential Directive/HSPD-5– ICS adopted as part of NIMS– All federal agencies/agencies
receiving federal funds must use NIMS-ICS
• NIMS-ICS — applicable to all incidents
ARFF11–7
Components of NIMS-ICS
• Common terminology• Modular organization• Integrated communications• Unified command structure
(Continued)
ARFF11–8
Components of NIMS-ICS
• Consolidated action plans• Manageable span of control• Pre-designated incident facilities• Comprehensible resource
management
ARFF11–9
NIMS-ICS Organizational Positions
• Five major positions — Command, Operations, Planning, Logistics, Finance/Administration
• Intelligence • IC retains responsibility until
delegated
ARFF11–10
NIMS-ICS Training
• All ARFF personnel • Offered through online resources• Scenario-based training allows
– IC and other personnel to work through decision-making process
– IC to make mistakes and learn through trial and error
ARFF11–11
In-Flight Emergencies
• Include fires and other problems —may lead to accident/incident
• Aircraft develop minor problems• Hydraulic failure or inoperative
landing gear — may cause serious problems
• Interior fire aboard an aircraft — true emergency
ARFF11–12
Ground Emergencies: Types
• Overheated wheel assemblies• Tire/wheel failures• Combustible metal fires• Fuel leaks and spills
(Continued)
ARFF11–13
Ground Emergencies: Types
• Engine fires or APU fires
• Uncontained engine failures
• Aircraft interior fires

ARFF11–14
Wheel Assemblies
• Aircraft wheels — commonly equipped with fusible plugs incorporated into the rims– Designed to melt, automatically
deflating tires– Reduces possibility of wheel collapse
and fragmentation
(Continued)
ARFF11–15
Wheel Assemblies
• WARNING! When responding to a hot brake incident or wheel fire, always approach from forward or aft of the wheel assembly while exercising extreme caution. Never approach from the sides in-line with the axle. In addition, always wear full protective gear including SCBA.
ARFF11–16
Hot Brakes
• Brakes/wheel assemblies frequently overheat
• Several methods to determine wheel temperature
• Prepare for a hot brake situation in certain cases
(Continued)
ARFF11–17
Hot Brakes
• Brown colored smoke coming from wheel assemblies
• Peak wheel temperatures — 30 to 45 minutes after aircraft has come to a complete stop
ARFF11–18
Cooling Hot Brakes
• Continue taxiing• Normal cooling• Water mist or fog pattern• Fans
ARFF11–19
Wheel Fires
• Safest approach — use large amounts of water from a distance using turrets
• Wear full protective clothing and SCBA
ARFF11–20
Combustible Metal Fires
• Variety of metals are used in aircraft– Magnesium– Titanium
• Initial fire control — water through turret application in heavy, coarse streams
(Continued)
ARFF11–21
Combustible Metal Fires
• Combustible metals around a high impact crash– Allowed to burn out– Buried
• Wear SCBA • Specialized Class D extinguishing
agents — magnesium and titanium fires
ARFF11–22
Fuel Leaks and Spills: Precautions
• Attempt to shut off the fuel• Avoid providing an ignition source• Evacuate aircraft if needed• Keep nonessential personnel clear • Wear full protective clothing
(Continued)
ARFF11–23
Fuel Leaks and Spills: Precautions
• Blanket exposed fuel surfaces • Contain spilled fuel to a small area • Prevent leaking/spilled fuel from
entering certain areas• Keep apparatus and equipment
ready • Position upwind and uphill
ARFF11–24
Fuel Spill Variables
• Size of the spill• Terrain• Weather conditions• Type of flammable liquid• Aircraft occupancy• Emergency equipment and
personnel available
ARFF11–25
Fuel Leaks and Spills During Aircraft Servicing
• Stop the fueling operation• Nonessential personnel should
leave the area• Notify safety personnel from the
airline and airport
ARFF11–26
Fuel Leaks and Spills
• Severity of the hazard created by a fuel spill — how volatile the fuel is and proximity to sources of ignition
• Avoid actions that could provide ignition sources for fuel vapors
• Maintenance personnel — check aircraft for damage/flammable vapors (Continued)
ARFF11–27
Fuel Leaks and Spills
• Keep maintenance records • May need to evacuate aircraft• Never start spark-producing
equipment• If fuel has entered sanitary sewers
or storm drains — dam inlets to prevent additional fuel from entering (Continued)
ARFF11–28
Fuel Leaks and Spills
• If sewer or storm drain contamination is extensive — keep sources of ignition away from manholes or storm drain inlets
• Thoroughly inspect aircraft onto which fuel has been spilled
(Continued)
ARFF11–29
Fuel Leaks and Spills
• WARNING! Unless ordered to do so by a responsible local official, never flush fuel or other contaminants into sewers or storm drains nor introduce water into these conduits in an attempt to dilute the contaminant.
ARFF11–30
Engine/APU Fires
• Crew may attempt to extinguish an engine or APU fire
• Unoccupied aircraft — be familiar with aircraft shutdown procedures
• Clean, gaseous extinguishing agents are the agents of choice
(Continued)
ARFF11–31
Engine/APU Fires
• Safest method of extinguishment — operate the engine or APU fire shutdown system

ARFF11–32
Uncontained Engine Failures
• “Uncontained engine failure or disintegration” versus “Contained engine failure or disintegration”
• Worst-case scenario — fragments pierce the fuselage/wing structure
• Uncontained engine failure — usually handled like a normal engine fire
ARFF11–33
Aircraft Interior Fires
• Occur for many reasons• Obtain information from ATC• Activate mutual/automatic aid • Pilot/firefighters communicate• Assign RIT team• Flight crew initiate evacuation
(Continued)
ARFF11–34
Aircraft Interior Fires
• Many common sources and areas of smoke/odor of something burning
• Smoke detection systems/extinguishing systems provided in aircraft
ARFF11–35
Aircraft Interior Fires: Methods of Detection
• Use portable infrared heat detectors or thermal imagers
• Remove sections of flooring, wall panels, and ceilings
(Continued)
ARFF11–36
Aircraft Interior Fires: Methods of Detection
• Exterior signs — paint blistering and discoloration
• Apply a light water mist and watch for steam areas
ARFF11–37
Aircraft Interior Fires: Gaining Entry and Evacuation
• Gain access if no sign of evacuation
• Do not impede exit of occupants• Over-wing exit size — entry may
be difficult • If entry can be safely made —
fought in the same manner as structural fires (Continued)
ARFF11–38
Aircraft Interior Fires: Gaining Entry and Evacuation
• WARNING! Exercise extreme caution when gaining entry into the aircraft due to the emergency escape slide systems attached to each door and, depending on the aircraft, to over-wing exits as well. If opened from outside, the escape slide may deploy and can seriously injure or kill unsuspecting emergency personnel.
ARFF11–39
Aircraft Ventilation
• Establish as soon as it is safe – Initial ventilation– Positive pressure ventilation– Hydraulic ventilation
• Vertical ventilation openings — made in the top of the aircraft
(Continued)
ARFF11–40
Aircraft Ventilation
• WARNING! Never discharge hoseline or turret streams into a hole burned or cut into the top of an aircraft. This will interrupt the vertical ventilation process and push the fire and products of combustion horizontally through the aircraft. (Continued)
ARFF11–41
Aircraft Ventilation
• Early ventilation is important
• Once ventilation is started– Gain entry– Initiate search– Begin fire attack
and rescue (Continued)
Courtesy of Doddy Photography.
ARFF11–42
Aircraft Ventilation
• Deploy the first interior attack hoseline — at an upwind overwing hatch or door
• Fire may spread in the belly of an aircraft — check areas
• All areas of fire involvement — accessed, extinguished, overhauled
ARFF11–43
Cargo Aircraft Interior Fires
• Differ from fires in passenger aircraft
• Flight crew is usually able to exit • Once crew are out, focus on fire
attack • Skin-penetrating nozzles may be
the best tactic to use • May need to take other actions
(Continued)
ARFF11–44
Cargo Aircraft
• Often impossible to move through the cargo hold
• Determine dangerous goods
• Request a hazardous materials response team
Courtesy of Doddy Photography.
ARFF11–45
Low-impact Crashes
• Do not severely damage or break up the fuselage
• Likely to have a large percentage of survivors
• First priority — ensure the safety of occupants and crew
(Continued)
ARFF11–46
Low-impact Crashes
• Initiate extrication operations only after donning full protective clothing and SCBA
• Handlines teams — support rescue personnel
ARFF11–47
Low-impact Crashes: Wheels-up or Belly Landings
• May result from a hydraulic system failure or other cause
• Fire is not uncommon • Aircraft scraping the ground — may
rupture fuel tanks/generate an ignition source
(Continued)
ARFF11–48
Low-impact Crashes: Wheels-up or Belly Landings
• Wheels-up landings– Nose gear up with the main gear
down – Single main gear up – Landing gear down but not locked
• Almost impossible for pilot to maintain control
(Continued)
ARFF11–49
Low-impact Crashes: Wheels-up or Belly Landings
• Upon touchdown aircraft — break apart or veer off runway
• May remain substantially intact• Occupants may leave on their own• Aggressive attack is critical if fire
occurs• Final attitude of the aircraft — may
hamper egress operations
ARFF11–50
Ditching
• A wheels-up landing on water• Water may be covered with fuel• Survivors and rescue personnel
most likely contaminated
(Continued)
ARFF11–51
Ditching
• Making an opening at a point above the water level – May permit air to escape – Cause the wreckage to submerge
• Will require specialized equipment • Use surface rescue techniques and
equipment
ARFF11–52
Rejected Takeoff with Runway Overrun
• Aircraft often intact, in large pieces
• Crash is usually survivable• Quick response/protecting the
egress route is vital • Many reasons for this type of
crash
ARFF11–53
Helicopters
• Do not withstand the violent forces encountered in vertical impact
• Avoid approaching aircraft while rotors are spinning
(Continued)
ARFF11–54
Helicopters
• Hazards associated with fuel tanks and fuel fires — the same for helicopters as for all other aircraft
Courtesy of Scott Ramey, S.D. Ramey Photography.
ARFF11–55
High-impact Crashes
• Crashes with severe damage to the fuselage and with a significantly reduced likelihood of occupant survival – Usually high speed, high angle
impacts– Little or no control of the aircraft– Tend to occur in off-airport areas (Continued)
ARFF11–56
High-impact Crashes
• Firefighters — scene security, protection of evidence, protection of exposures
• Characteristics of high-impact crashes– Fuselage is substantially damaged– G-forces exceed human tolerance levels– Seats and safety belts fail to restrain
passengers(Continued)
ARFF11–57
High-impact Crashes
• Aircraft often break apart upon impact
• Hitting obstructions — aircraft may cartwheel
• May encounter burning items • Wind — spread the fire • Airport/department — determine
response criteria
ARFF11–58
Controlled Flight Into Terrain
• Pilots can often control where a plane will crash
• Controlled flight into terrain — guiding a crashing aircraft to its destination
ARFF11–59
Crashes Involving Structures
• More complex problem • First-arriving officer take action• Aircraft may break open upon
impact• Rescue personnel — search and
evacuate area
(Continued)
ARFF11–60
Crashes Involving Structures
• Take steps to prevent fuel from spreading
• Take precautions to eliminate sources of ignition

• Operations conducted upwind – Safer – More efficient
ARFF11–72
Terrain
• Ground features– May be readily apparent– May not be as obvious
• Consider terrain when establishing areas
ARFF11–73
Wreckage
• Evaluate wreckage and hazards it creates
• Different methods of attack may be required
• Confirm initial fire fighting efforts are aimed at a portion of the fuselage
ARFF11–74
Survivors
• Occupants help determine the point at which rescue efforts should begin
• May need to decide upon the rescue entrance
• If evacuation has begun perform certain actions
ARFF11–75
Hazardous Areas
• Aircraft propellers
• Jet and gas turbine engines
• Line of fire• Wings• Jagged metal
(Continued)
• Advanced aerospace materials

ARFF11–77
Initial Attack/Fire control
• Fire and crash conditions — govern placement of apparatus for initial attack
• Main objective — rescue of occupants trapped within the aircraft
• Take certain actions — accidents with fire/high likelihood of fire (Continued)
ARFF11–78
Initial Attack/Fire control
• Be familiar with the cabin length of the aircraft prior to entry
• In nonfire accidents, follow the same basic procedures
• Assist evacuation if started • Extending booms assist in
extinguishing fires (Continued)
ARFF11–79
Initial Attack/Fire control
• Involves initial mass application of an extinguishing agent
• Begins during the approach of the fire fighting vehicles
• Structural apparatus — can be effective on aircraft fires by using AFFF
(Continued)
ARFF11–80
Initial Attack/Fire control
• If fire is confined to the engine nacelles or wings — stop the fire at the wing root or engines
• If fuel is leaking from fuel tanks and spreading on the ground — keep the fire from the fuselage and egress areas
ARFF11–81
Aircraft Accident Victim Management
• High-impact crash — EMS role may be limited to treating rescuers
• Low-impact crash — presents rescuers with the greatest challenge in treating and transporting victims
• Ensure personal protection against bloodborne pathogens (Continued)
ARFF11–82
