System Use, Passengers & Attendants:
Oxygen System                                           ACTIVATED
Individual oxygen masks are automatically released from passenger service units when cabin altitude is at or above 14,000 feet.
Warning:  NO SMOKING

Portable Oxygen:
Portable oxygen cylinder assemblies are positioned in the cockpit and cabin for use if required.
Instructions for use are affixed to the cylinders.


Exits:

The ten main entry doors and the crew service door may be used as emergency exits.
An inward opening overhead hatch in the cockpit may be used in an emergency.
The installation includes five self contained inertia reel descent devices.

Exits - Special Freighter:
- Main entry doors 1L and 5L and the crew service door may be used as emergency exits.
- An inward opening overhead hatch in the cockpit may be used in an emergency.  The installation includes self-contained inertia reel descent devices with eight (or five) emergency escape harnesses.




Evacuation Slide / Rafts:

Passenger Doors - 1, 2, 4, & 5 - L & R
With the mode selector in AUTOMATIC position, rotation of the interior door handle actuates the emergency power system and positions the door to the full open position.
The flight attendant must release the handle and continue to push outward, using the assist handle on the door surround panel, until the door is in the full open and latched position.
The escape slide/rafts automatically deploy and inflate when the door is fully opened.
Note:  If the slide/raft does not inflate automatically, pull the manual inflation handle on the slide raft girt.

Passenger Doors - 3 L & R
Opening door 3 using the interior door handle with the mode selector in AUTOMATIC actuates the emergency power system for the door and positions the door to the full open position.
The flight attendant must release the handle and continue to push outward, using the assist handle on the door surround panel, until the door is in the full open and latched position.
The door mounted escape ramp and the fairing mounted off-wing escape slide automatically deploy.
An off-wing deployment indicator is visible to the cabin attendant at door 3 when the off-wing escape slide is properly deployed.
Note:  If the ramp does not inflate automatically, pull the inflation handle on the hinged end of the door.
If the off-wing escape slide does not inflate automatically, pull the manual deployment handle (on sidewall adjacent to the door).

In a ditching situation, deployment of the off wing escape slide is not desirable; however, the ramp should be used for access to the life rafts.
This configuration is attained with the Mode Selector in AUTOMATIC and the ditching deactivation handles (on sidewall adjacent to door) activated. 
This prevents the off-wing escape slide from automatically sequencing.

Passenger Door - Interior View:
To releasse slide/raft for flotation:
Step 1 - Disconnect door strap
Step 2 - Raise flap and pull handle


Escape Slide - Upper Deck Door:


The escape slide for the upper deck door(s) is mounted on tracks immediately inboard of the door.

A mechanical latch locks the pack inboard in either AFT stowed position (clear of the doorway) or FWD armed position (aligned with the doorway).

The escape slide pack must be in the forward position when operating the airplane.

Moving the door to full open automatically unlatches the pack from its base and activates the pack deploy system to rotate the pack through the doorway.

As the slide falls from the chute automatic inflation occures.  If inflation does not occur, pull down on the manual inflation handle.
Caution:  When opening the upper deck door for normal crew use the slide pack must be in the aft stowed position.

Smoke Barrier - Straight Stair


Main Entry Door Operation During Upper and Main Deck Smoke Evacuation:
In order to accomplish the Upper and Main Deck Smoke Evacuation procedure, main entry doors will need to be secured in the partially open position.
Ditching rope above door No. 3 may be utilized to secure door no. 2 or No. 4 without detaching from the compartment.
Note:  If the rope is not available, use any satisfactory item in the same manner to secure the doors

Attach snap end of rope to door assist handle on AFT door frame, place door operating handle to vertical (12 O'clock position), secure handle with several loops and return rope through assist handle and tie.
Pressure on the door will maintain tension on the rope so it may be left unattended.

Supplementary Information

Evacuation Slide/Rafts

Passenger Doors:

When the mode selector handle is in AUTOMATIC position and the interior door handle is moved toward OPEN position, the door begins to open and the power assist opening system activates.

The flight attendant  must release the operating handle and continue to assist the door opening motion by using the assist handles on the door and on the door surround panel, until the door is full open and latched position.

The door mounted escape slide/raft (and slide ramp in the case of door #3) automatically deploys and inflates.
If the slide/raft does not inflate automatically, pulling the manual inflation handle inflates the slide/raft.
If the door is to be opened from the interior and slide deployment is not desired, the mode selector handle must be in the MANUAL position.

If the mode selector handle is in AUTOMATIC position and the door is opened using the exterior handle, the mode selector handle is mechanically positioned to MANUAL and the door can be opened without slide deployment.

When the door is closed using either the exterior or interior door handles, the mode selector handle remains in MANUAL and must be positioned to AUTOMATIC by cabin personnel to provide for automatic sequencing if required.
The mode selector handle should not be repositioned (from MANUAL to AUTOMATIC or AUTOMATIC to MANUAL) unless the door is fully closed.
Note:  If both body gear are not extended, the airplane may tip tail down when on the ground; emergency escape slide/rafts at main doors 1 and 2 (as installed) and emergency escape slide(s) at upper deck doors are unusable.


Rafts:

Stowage provisions for twenty one 25-man life rafts are provided in overhead compartments adjacent to each passenger door.
However, life rafts will only be installed above doors 3 L and R.


Emergency Lighting:

Interior emergency lighting consists of door, aisle, cross aisle and exit lights, and luminescent exit signs.

Exterior lighting consists of escape slide and overwing lights.

Emergency escape path lighting consists of floor mounted locator lights spaced at approximately 40 inch intervals in the aisle, cross-aisles and stairway.
Additional battery powered exit identifier lights are located at each cabin exit.
When illuminated, the escape path lighting provides guidance for emergency evacuation if all sources of cabin lighting more than four feet above the aisle floor are obscured by smoke.

Each emergency light unit is powered by its own battery.
Under normal operation, the battery charge is maintained by a trickle charge from the 28V DC essential bus.
A fully charged battery should provide approximately twenty minutes of power.

External emergency lighting is designed to illuminate all escape slides, ramps and overwing areas.
Emergency lights for doors 1, 2, 4 and 5 are mounted on the door. 
Door 3, which opens over the wing, has one light flush mounted in the door sill to illuminate the escape ramp area. 



Four flush mounted fuselage lights illuminate the over-flap escape slide.





The crew service door escape slide is illuminated by two flush-mounted door sill lights.


Smoke Barrier:

The smoke barrier is used to prevent smoke on the main deck from entering the upper deck through the stairway when the aiplane is on the ground.
 If smoke on the main deck prevents upper deck occupants from safe egress, using main deck entry doors and slides, the smoke barrier should be deployed to cover the stairwell.  Upper deck occupants can then evacuate using the upper deck door slide.


Evacuation Signal Alarm:

Placing the guarded Emergency Evacuation Command Switch on the pilot's overhead panel to ON, or pressing ALERT COMMAND switch at Door 1L with COMMAND switch at ARM activates EVAC/ALERT at all six stations.
HORN SHUTOFF (AURAL RESET) switch silences the horn at the respective station, but ALERT (EVAC) light continues to flash as long as COMMAND switch is ON or until ALERT COMMAND switch is again pressed.

Miscellaneous Emergency Equipment:

Escape ropes, chemical and water fire extinguishers, power megaphones, portable oxygen bottles, crash axes, automatic radio beacons and first aid kits are stowed at strategic stations throughout the cabin.
Life vest are stowed at each crew member's station and at each passenger's seat.
