INTRODUCTION

Each jurisdiction must have established procedures for responding to all types of all typesof aircraft emergencies. All firefighters must understand their role in the overall operation so that allnecessary functions are accomplished rapidly and effectively. While response procedures varyfrom jurisdiction to jurisdiction, this section highlights some of the more common procedures thatmost agencies should incorporate into their standard operating procedures.

STANDARD AIRCRAFT EMERGENCY RESPONSE

Runway standby positions for ARFF vehicles in anticipation of an emergency should bepredetermined in a standard operating procedure. In event of an emergency, units should godirectly to these positions unless directed elsewhere. Responding units should, if possible, havethe following minimum information concerning the accident:

a. Make and model of aircraft.b. Emergency situation.c. Response category.d. Amount of fuel on board.e. Number and locations of occupants, as well as injured, if known.f. Nature and location of any cargo of critical significance.g. Location of aircraft (if landing, the runway to used; if crashed, the site)

While time is essential, ARFF personnel must temper their response with discretion, takingweather, visibility, terrain, and traffic into consideration. Promptness and safety are equallyimportant response considerations. The fire department section of the airport emergency planshould include response routes to be used unless unforeseen conditions dictate otherwise. Thisprocedure allows all unit to anticipate the actions of other units. The following are considerationsfor selecting these routes:

a. Probable accidents sites.b. Presently available routes (location of frangible crash gates)c. Possible alternative routes.d. Design of apparatus (weight, height, width, etc.)e. Load capacity of bridges, ramps, etc.f. Terrain (rough, even, paved, unpaved, flat, hilly, etc)g. Effects of weather.h. Other obstacles.

If, for any reason during an emergency response, a driver’s vision becomes obs cured, thedriver should approach the scene using extreme caution to ensure that he does not strike fleeing

occupants with the moving vehicle. If two people are on board, one person should get out of thevehicle and sweep the area in front of the vehicle to ensure that it is clear and that occupants willnot be run over. If the apparatus driver/operator should lose sight of the firefighter on foot, thedriver/operator must stop the apparatus immediately to avoid the possibility of running over thefirefighter. Response must not be resumed until visual contact has been re-established. Duringnight operations, flashlights may be needed to direct apparatus safely onto the scene.

They must also respond in a way that avoids damaging the responding apparatus andequipment. They should avoid running over aircraft debris scattered throughout the accidentscene. Preserving the accident scene and safeguarding evidence is a responsibility of all ARFFpersonnel.

Response time to aircraft accidents is critical to initiating an effective rescue effort. Theauthority having jurisdiction for their respective airport may require the primary airport ARFFapparatus be able to respond from the station to the midpoint of the most distant runway and begin

application of extinguishing agent within three minutes of notification. Additional apparatus must beable to respond and begin extinguishment within four minutes. In any case, ARFF personnelshould be aware of the standards of response based on the authority having jurisdiction for eachrespective airport.

UNANNOUNCED EMERGENCY RESPONSE

An una nnounced eme rgency is one that occurs without prior warning. With in-flight(announced) emergencies, ARFF personnel are usually given certain pre-approach informationbefore the aircraft attempts to land. However, in either case, the available information may besketchy, such as "Aircraft on fire on the approach end of runway one-seven”.

SIZE-UP

The first firefighter or company officer to arrive at the scene should perform a quick size-up.This initial Incident Commander should develop an action plan that allows for the best possible fireattack on the aircraft while remembering egress routes, wind direction, terrain and aircraft attitude.More information on size-up is described later in Fire and Supervisor course.

INITIAL ATTACK/FIRE CONTROL

Existing fire and crash conditions govern the placement of fire fighting apparatus for theinitial attack. The main objective during this attack is the rescue of occupants trapped within theaircraft. Fires threatening these areas should be extinguished as soon as possible. Other nonthreatening fires may be left for later-arriving units. At times, it is difficult to distinguish betweenrescue and extinguishment activities because they are interrelated and are often performedsimultaneously.

Two important factors in the initial fire attack and rescue size-up are whether survivors arebeing evacuated before the fire fighting apparatus arrives and whether the aircraft fuselage isintact. If the flight crew has begun evacuating the occupants, the first-arriving unit should establisha safe exit to permit evacuation to continue and to make sure that the escape chutes remain intactand free of fire. If the fuselage is not intact, more than one rescue area may have to beestablished. Utilization of extending booms may assist in extinguishing fires in the confined areasof a crash scene. Application consisting of low sweeping patterns and the conservation of agentare critical to ensuring both occupant and firefighter safety.

Quickly controlling an area of fire to establish a safe egress area involves initial massapplication of an extinguishing agent. In the case of specially designed aircraft fire fighting

apparatus, turrets and ground sweeps should be used to control the fire around the exterior of thefuselage. Handlines should be used for backup, interior attack, and overhaul. The initial attackbegins during the approach of the fire fighting vehicles. Roof turrets, bumper turrets, and groundsweeps should be used as soon as the vehicles are within range of the aircraft's occupiedsections. However, because limited quantities of extinguishing agents are carried on apparatus,turrets should be used only when the agent can be applied without being wasted. The initialdischarge of foam should be made along the fuselage in order to prevent fire from impinging on itand to begin to create an exit.

Although structural apparatus may lack specialized delivery systems, they can still beeffective on aircraft fires by using aqueous film forming foam (AFFF). Given an adequate supply of AFFF and additional water available from hydrants, relays, or drafting sources, structural apparatus

can sustain an effective attack as long as necessary. Wide coverage and considerable heatabsorption can be achieved by using larger handlines and master stream appliances withappropriate fog nozzles.



AAF 1.4 – 4

During the control phase of an exterior fire, all efforts should be directed at insulating andisolating the occupied portions of the aircraft. This process is done by concentrating theextinguishing agents on the occupied portions of the aircraft and the surrounding areas. Whenconditions permit, ARFF personnel should position the apparatus at the nose or tail of the aircraftso they can apply agent on either side of the aircraft (Figure 1). Thus, they may keep the aircraftinterior acceptable for occupants to survive while rescue personnel remove them through a

controlled exit to safety. If fire is confined to the engine nacelles or wings, personnel shouldattempt to stop the fire at the wing root or engines. If fuel is leaking from fuel tanks and spreadingon the ground, personnel should attempt to keep the fire from the fuselage and egress areas atleast until the occupants have been evacuated or rescued.

In accidents involving fire or a high likelihood of fire, the initial attack is usually made withone or more units operating both roof and bumper turrets while additional units perform handlineoperations (Figures 2) and interior attack in an attempt to establish a safe area in and around theaircraft exits. This attack is followed up with rescue personnel, protected by handlines, makingentry into the aircraft. Water supplies must be adequate to support interior fire fighting operations. ARFF personnel should be familiar with the cabin length of the aircraft prior to entry to ensure thatample hose line is taken into the aircraft. In nonfire accidents, the same basic procedures should

be followed. Instead of fighting fire, however, firefighters must blanket fuel spills with foam andcharged handlines. At the same time, vehicle turrets must be kept ready in case fire erupts.

CONCLUSION

This training session is designed to educate driver/operator who are responsible for operating apparatus equipped with fire pumps. This information in this topic aids the driver/operator in meeting the Assessment Criteria found in Perform functions as an Operator of Fire Tender.
