EMERGENCY EQUIPMENT

GENERAL

The emergency equipment sectiondescribes and illustrates the systemsand equipment which are essential to thesafety of passengers and crew duringadverse operational conditions. Theseinclude passenger evacuation commandsystem, emergency equipment locations,passenger and crew oxygen systems,emergency lighting and escape slide/rafts. The description for the emergencyoperation of the cabin doors, the cockpitdoor, and the clearview windows are alsodetailed in this chapter.

PASSENGER EVACUATIONCOMMAND SYSTEM

The Passenger Evacuation CommandSystem provides an aural means of alert-ing crew and passengers that an emer-gency evacuation is imminent. The sys-tem consists of an evacuation COMMANDswitch, an EVAC horn, a HORN SHUT-OFF button and an EVAC light on theoverhead panel. In addition, an EVACHORN, a horn off button, an evacuationswitch and an EVAC light is installed atall cabin attendants' stations. The sys-tem is manually actuated by the COMMANDswitch on the cockpit overhead panel, orthe EVAC switch at the attendants stations,providing the pilot's switch is in ARM.

OXYGEN SYSTEM

GENERAL

Two independent emergency oxygen sys-tems are provided: one for the flightcrew, and one for the cabin attendantsand passengers. The cockpit oxygen issupplied from a storage cylinder. Thecabin and lavatory areas are suppliedby individual, self-contained chemicaloxygen generating/dispensing units. Inaddition, portable cylinders are locatedin the cockpit and cabin.

DESCRIPTION

Flight Crew Oxygen System

The flight crew oxygen system is thepressure-breathing, diluter-demandtype, and is provided for supplementaland emergency requirements. Oxygenfrom a high pressure storage cylinder isreduced to a regulated low pressure,then distributed to five flight crew sta-tions. Individual quick-donning maskswith mask-mounted regulators are pro-vided at each flight crew station. Eachmask is positioned for immediate use.Smoke goggles are also provided, andare stowed at each of the five flightcrew stations.

Passenger Oxygen System

The oxygen generating/dispensing unitssupply supplemental oxygen to occupantsof the cabin and lavatories. Each unitincludes a chemical oxygen generator,oxygen mask(s) with reservoir bag(s),and hoses to convey oxygen from thegenerator to the mask(s).

A two- or three-mask unit is installedin one seatback for each pair of seats ineach row. Occupants of front row seatsin each cabin section are supplied bytwo- or three-mask units in compart-ments in the ceiling, sidewall stowagecompartments, or class dividers justforward of the seats.

A one-mask unit is installed in theoxygen compartment of each cabinattendant station console. A two-maskunit is installed in each lavatory ceiling.

All oxygen compartment doors open auto-matically if the cabin altitude exceedsapproximately 14,000 feet. Removing anyone mask from a single- or multiple-maskunit compartment and pulling the masktoward the face so that the lanyard sepa-rates from the generator initiates theoxygen generating process and oxygenautomatically flows through all masks inthat compartment. The generators pro-vide sufficient oxygen for at least 15minutes continuous use.

CAUTION; THE OXYGEN GENERATORSURFACE TEMPERATUREMAY REACH 500°F (260°C)WHEN GENERATING OXY-GEN. DO NOT TOUCH ORATTEMPT TO REMOVEGENERATOR. BURN INJURYCAN RESULT. IF ANACTIVE GENERATOR ISINADVERTENTLY REMOVEDFROM COMPARTMENT, ITMUST BE PLACED INMETAL CONTAINER SUCHAS LAVATORY OR GALLEYSINK. HEAT WELL SCORCHOTHER MATERIALS ORFABRICS.

NOTE; Odor similar to scorched clothmay be created by activation ofgenerators. The odor does notaffect the purity of the oxygenand there is no fire hazard.

Masks are continuous flow type. No shut-off valves are provided. Oxygen flow ratesare low, so oxygen reservoir bags may notinflate fully between breathing cycles. In-flation rate is dependent on cabin altitudeand elapsed time since generator activa-tion. On some masks, an inflation indica-tor, small green compartment at the inletend of mask reservoir bag, inflates pro-viding evidence of oxygen flow-

As a backup to the automatic system,the oxygen mask switch on the Flight

JLNov 1/78 07-20-01

Engineer's Upper Panel provides a man-ual override for releasing the masks.Moving the switch to EJECT will openall oxygen compartment doors.

If necessary, each individual oxygencompartment door also can be openedmanually. Seatback-mounted compart-ment doors can be opened by inserting afinger or small diameter rod through thehole in the bottom of the compartment,and applying pressure to release thelatch. Access to the hole in the bottomof the compartment is through the seat-back tray compartment. The tray mustbe unlatched and pulled from the com-partment to expose the hole.

All other oxygen compartment doors canbe opened by inserting a small diameterrod or pointed object into the slot in thedoor. Make contact with the latch open-ing mechanism, apply pressure 90degrees to the direction of the slot andmove the object to release the latch.

When manually opening the door, careshould be taken to avoid damaging thedecorative appearance of the door.

Portable Oxygen Cylinders

One portable oxygen cylinder (with smokemask attached) is located in the cockpit.Attendant's/First Aid portable oxygencylinders and masks as required arelocated in the cabin. Refer to EmergencyEquipment Location Diagram for loca-tions of the cylinders.

CONTROLS AND INDICATORS

The controls, indicators, and componentsare located on the Flight Engineer'sUpper Panel No. 1 and No. 2, the crewmembers stations, and throughout thecabin and lavatories. Illustrations ofthe major panels may be found byreferring to Chapter 1. Locations ofcomponents and individual controls andindicators are illustrated and describedin other sections of this chapter.

EMERGENCY LIGHTING

GENERAL

The emergency lighting system consistsof cabin ceiling lights, exit signs, galleylights, door lights, and cockpit domelights. External emergency lighting isprovided by electrical lighting as anintegral part of the escape slides andramps.

DESCRIPTION

Electrical power for emergency evacua-tion lighting system control and operationis supplied by the aircraft electricalsystem or from independent batterypacks located in the cabin. These bat-teries are self-contained and continuouslycharged. Power is provided sequentiallyin the following priority: right emer-gency ac bus; left emergency dc bus;emergency battery packs. All packs aremaintained at full charge by individualchargers powered from the aircraftelectrical system. When fully charged,

the packs will provide sufficient powerto operate the emergency lights for atleast 10 minutes. Emergency lightingsystem control is either automatic ormanual, as selected in the cockpit or atthe left forward cabin attendant's controlpanel.

In the automatic mode, a logic unit con-trols the system. In case of powerinterruption, the system will be switchedautomatically to the next available sourceof power. This provides power for emer-gency lighting without depleting batterypack power below the level required fordispatch.


The controls, indicators, and annunciatorlights are installed on the overhead panelin the cockpit and on the left forwardcabin attendant's control panel. Illustra-tions of the major cockpit panel may befound by referring to Chapter 1. Theindividual controls and indicators aredescribed in the following illustration.

EMERGENCY EXITS

GENERAL

Cabin doors will be used for emergencyexits for both crew and passengers. Allof the normal exits have backup systemsto permit their operation during abnor-mal conditions. For the flight crew,alternate exit routes are provided througheither the cockpit door blowout panel intothe forward cabin or by opening the clear-view windows.

DESCRIPTION

Cabin Doors

There are eight main cabin doors, fouron each side of the aircraft. From out-side the aircraft all of the operatinghandles are identical and all are openedin the same manner in the event of anemergency. From inside the aircraft,the six aft doors have identical handlesand identical emergency opening proce-dures. The two forward cabin door handleshowever, are not identical to the aft sixand are operated differently. Power forthe emergency opening of all cabin doors ispneumatic. An air reservoir and a pres-sure indicator are provided at each door.If the emergency door opening procedureis performed from inside the aircraftwith emergency pneumatic power theassociated escape slide will deploy auto-matically. When using emergency pneu-matic power to open the doors from theinside, slide deployment is prevented by

holding the slide arming lever in theemergency interlock override position.A manual lift bar is installed on allcabin doors to provide a means foropening the doors from inside the air-craft when no emergency pneumaticpower is available. The manual lift barcan only be used when the door handle inthe emergency position. At least twopeople may be required to open a door bythe manual lift method.

Cockpit Door

The cockpit door provides access to themain cabin from the cockpit. In theevent the door is jammed, a blowoutpanel on the lower half can be unhingedor kicked open. This provides anadequate crawl-through opening to the maincabin and the normal evacuation routes.

Clearview Windows

Two sliding clearview windows providean alternate emergency escape route forthe flight crew. The clearview windowsare adjacent to the windshields. Escapelines are provided to allow the crew tolower themselves to the ground.


An emergency equipment location draw-ing, in another section of this chapter,locates the major emergency equipmentand facilities. Individual controls andindicators are also illustrated anddescribed.

CABIN DOORS - Inadvertent Pneumatic Discharge In Flight (SHEET 1)

Refer to Sheet 2 for procedures.

NOTE

Inadvertent actuation of a cabin door control han-dle, to Emergency (pneumatic) Open position, in-flight will discharge the corresponding doorpneumatic bottle. Discharging the bottle will notopen the door inflight unless cabin differentialpressure is less than approximately 0.55 psi.Cabin differential pressure above approximately0.55 psi will keep door closed. With door closed,pneumatic bottle pressure will bleed off within afew seconds, leaving no residual pressure thatcould force door open even if cabin differentialpressure is relieved.

CAUTION

When operating with cabin differential pressureof less than 1 psi, crew should caution cabinattendants to ensure that unauthorized personnelremain clear of doors.

Procedures which may result in prolonged periodsof operation at low differential pressure are:

• DECOMPRESSION AND EMERGENCY DESCENT

• COCKPIT SMOKE REMOVAL UNPRESSURIZED

• RAM AIR VENTILATION OPERATION

• CABIN OR COCKPIT SMOKE OR FUMES

• COCKPIT PREPARATION FOR PASSENGER EVACUATION

NOTE

Immediately following inadvertent discharge of acabin door pneumatic bottle, reset door controlhandle from emergency (pneumatic) to neutral po-sition. This locks door in closed position untilready for subsequent operation.

ESCAPE SLIDE/RAFTS

An inflatable escape slide/raft (combi-nation escape slide and life raft) isinstalled in a slide stowage container,mounted on the inside of each cabindoor. Opening the door will automati-cally inflate and deploy the slide whenthe arming lever adjacent to the door isin the SLIDE ARMED configuration.Should a door, other than the overwingdoors, become jammed and cannot beopened, the slide/raft may be moved toa usable door for deployment and useas a raft. A step-by-step procedure toremove the slide/raft from the jammeddoor and move it to another door fordeployment is illustrated in this section.

A manual inflation handle is installed inthe slide/raft assembly and becomesvisible when the slide/raft is deployed.If the automatic inflation mechanismmalfunctions the manual handle must bepulled to inflate the slide/raft.

The cabin doors are equipped with double-track slide/rafts so that two persons canexit the airplane simultaneously. Theoverwing slide/rafts are fitted with inte-gral ramps and deploy over the leadingedge of the wing, outboard of the enginepylon. When the overwing slide/raftsare deployed and ready for use, slideposition indicators will be visible on theupper end of the slide/rafts.

Each slide/raft and ramp is equipped withself-powered, battery operated electric

lights as an integral part of the slide/raftand the ramp. The lights illuminate theevacuation route from the passengercompartment to the ground/water.

Side handles are provided at the lowerportion of the slide so that the firstevacuees to exit during a ground evacua-tion can help hold the slide in position,if necessary. Also attached to eachslide/raft is a re-entry/mooring line tobe used as an aid to re-enter the airplane,if necessary, or to moor the slide to theairplane when used as a raft during eva-cuation and ditching.

Each slide can be released quickly fromthe airplane and used as a life raft. Aslide disengagement cable with an attach-ed fabric handle is located at the top ofthe slide. The cable and handle are pro-tected by a fabric flap. The slide/raftmay be disengaged by lifting the protec-tive flap and pulling the handle placardedPULL. The slide/raft may be releasedfrom the airplane by unfastening/cuttingthe re-entry/mooring line.

An integrally lighted slide inflation cylin-der low pressure light is installed on thedoor, directly over each slide/raft stow-age container. The light will automati-cally come on when the inflation cylinderhas insufficient pressure to inflate theslide/raft. The integrity of the indicatorlight and electrical circuit may be testedby pressing the light. A faulty circuit isindicated when the light does not come onwhen pressed.
