Passenger Cabin Signs

The passenger cabin signs are controlled by a switch on the forward overhead

panel. With Auto selected, the signs are controlled automatically by reference to

landing gear and flap positions:

FASTEN BELTS and RETURN TO SEAT signs:

• illuminate when flaps or gear are extended

• extinguish when flaps and gear are retracted.

NO SMOKING signs:

• illuminate when gear is extended

• extinguish when gear is retracted.

All passenger signs can be controlled manually by positioning the respective

switch to ON or OFF.

When the passenger cabin signs illuminate or extinguish, a low tone sounds over

the PA system.

Emergency Lighting

Exit lights are located throughout the passenger cabin to indicate the approved

emergency exit routes. The system is controlled by a switch on the overhead panel.

The switch has three positions, OFF, ARMED and ON and is guarded to the

ARMED position. With the switch in the ARMED position, the emergency exit

lights are normally extinguished. If electrical power to DC bus No. 1 fails or if AC

power has been turned off, the emergency exit lights illuminate automatically.

The emergency exit lights may also be illuminated by a switch on the aft

attendants panel. Lifting the guard and pushing the switch ON overrides the flight

deck control and illuminates the emergency exit lights. Control from this panel is

available in the event of failure of the automatic control.

The flight deck aft DOME light contains a separate bulb that is powered by the

emergency lighting system to provide for flight deck evacuation.

Interior Emergency Lighting

Interior emergency exit lights are located:

• in the lower inboard corner of stowage bins to illuminate the aisle

• over the entry/service and overwing emergency hatches to indicate the

door and hatch exits

• in the ceiling to locate the exits and provide general illumination in the

area of the exits.

Self-illuminating exit locator signs are installed at the forward, middle, and aft

end of the passenger cabin.

Floor proximity emergency escape path lighting consists of locator lights spaced

at regular intervals down one side of the aisle. Lighted arrows point to overwing

exits and a lighted EXIT indicator is near the floor by each door and overwing exit.

Escape path markings are provided for visual guidance for emergency cabin

evacuation when other sources of cabin lighting are obscured.

Interior Emergency Lighting

[Option: Photoluminescent Lighting System]

Interior emergency exit lights are located:

• in the lower inboard corner of stowage bins to illuminate the aisle

• over the entry/service and overwing emergency hatches to indicate the

door and hatch exits

• in the ceiling to locate the exits and provide general illumination in the

area of the exits.

Self-illuminating exit locator signs are installed at the forward, middle, and aft

end of the passenger cabin.

A photoluminescent floor path marking system is installed along the cabin aisle.

The photoluminescent material, when excited by light, will glow and provide exit

path guidance. At the exit, electrically operated lights and markers provide exit

identification.

The photoluminescent strips need to be properly charged. The table below

contains charging information and can be used to determine how long the strips

remain illuminated. For charging, the cabin ceiling, and sidewall lights need to be

on at full intensity, and the strips should not be covered or blocked.

Flight Crew Oxygen System

The flight crew oxygen system uses quick-donning, diluter-demand masks/

regulators located at each crew station. Oxygen is supplied by a single cylinder.

Oxygen pressure is displayed on the Oxygen Pressure indicator located on the aft

overhead panel when the battery switch is ON. Oxygen flow is controlled through

an in-line, pressure-reducing regulator to supply low-pressure oxygen to the

regulator on the mask. System pressure may be as high as 1850 psi.

Oxygen flow is controlled by a regulator mounted on the oxygen mask. By

pushing the NORMAL/100% control lever, the regulator is adjusted from the

air/oxygen mixture to 100% oxygen. By rotating the EMERGENCY/PUSH TO

TEST selector, the regulator is adjusted to supply oxygen under pressure.

Flight Crew Oxygen Mask Usage

Donning Instructions

To don the mask, grasp the regulator with the thumb and forefinger and remove

from stowage. Squeezing the inflation levers and removing from the box:

• inflates the mask harness

• momentarily displays a colored oxygen flow indicator.

• Place the mask over the head and release the levers. The harness contracts

to fit the mask to head and face.

The observer’s oxygen mask, regulator, and harness unit is the same as the pilots’.

Mask Donning

Portable Protective Breathing Equipment

Protective Breathing Equipment (PBE/Smoke Hood) devices for crew use (for

combating fires and/or entering areas of smoke or fume accumulation) may be

stowed throughout the airplane; however, they are normally found in the forward

and aft sections of the passenger cabin. The device is placed over the head and,

when activated, provides approximately

15 to over 20 minutes of oxygen

depending upon the device used. Manufacturer’s operating instructions are

placarded on the container.

Passenger Oxygen System

The passenger oxygen system is supplied by individual chemical oxygen

generators located at each Passenger Service Unit (PSU). Four continuous flow

masks are connected to each generator. A generator with two masks is located

above each attendant station and in each lavatory.

1.40.13

Airplane General, Emergency

Equipment, Doors, Windows -

Systems Description

Boeing 737 Operations Manual

The system is activated automatically by a pressure switch at a cabin altitude of

14,000 feet or when the Passenger Oxygen Switch on the aft overhead panel is

positioned to ON. When the system is activated, the PASS OXY ON light

illuminates and OVERHEAD illuminates on the Master Caution System.

Activating the system causes the masks to drop from the stowage compartments.

The oxygen generators are activated when any mask in the unit is pulled down.

Pulling one mask down causes all masks in that unit to come down and 100%

oxygen flows to all masks. A green in-line flow indicator is visible in the

transparent oxygen hose whenever oxygen is flowing to the mask. Oxygen flows

for approximately 12 minutes and cannot be shut off. If the passenger oxygen is

activated and a PSU oxygen mask compartment does not open, the masks may be

dropped manually.

the flow of oxygen is constant, whether or not the mask is

being worn.

WARNING: Do not use passenger oxygen with cabin altitude below 14,000

feet when smoke or an abnormal heat source is present. The

use of passenger oxygen does not prevent the passengers from

inhaling smoke. Air inhaled is a mixture of oxygen and cabin

air.

Passenger Portable Oxygen

First aid and supplemental portable oxygen cylinders are installed at suitable

locations in the passenger cabin. The cylinders are fitted with a pressure gage,

pressure regulator and on-off valve. The cylinders are pressurized to 1800 psi. At

this pressure and a temperature of 70 degrees Fahrenheit, (21 degrees Celsius) the

cylinders have a capacity of 4.25 cubic feet (120 liters) of free oxygen. Two

continuous flow outlets are provided on each cylinder, one regulates flow at two

liters per minute for walk-around; the second outlet provides flow at four liters per

minute. The four-liter flow is used for first aid.

Duration can be determined by dividing capacity by outflow (120 liters divided by

4 liters/minute = 30 minutes).

Halon (BCF) Fire Extinguishers

Halon (BCF) fire extinguishers contain a liquefied gas agent under pressure. The

pressure indicator shows an acceptable pressure range, a recharge range, and an

overcharged range. A safety pin with a pull ring prevents accidental trigger

movement. When released the liquefied gas agent vaporizes and extinguishes the

fire. The extinguisher is effective on all types of fires, but primarily on electrical,

fuel and grease fires.

Fire Extinguisher Usage

Each class of fire calls for specialized action. Using the wrong extinguisher may

do more harm than good. For your own protection, you should know these basic

types, how to use them, and why.

CLASS OF FIRES

EXTINGUISHER TYPE

There are three common classes of fire:

CLASS

COMBUSTABLE - paper, wood, fabric, rubber,

TYPE

MATERIALS

certain plastics, etc., where

Water (H2O) saturates

material and prevents

rekindling.

CLASS

FLAMMABLE

- gasoline, oils, greases, solvents,

TYPE B

LIQUIDS

paints, burning liquids, cooking

BCF (Halon 1211)

fats, etc., where smothering

action is required.

CLASS

LIVE

- fires started by short circuit or

TYPE C

ELECTRICAL

faulty wiring in electrical,

BCF (Halon 1211)

electronic equipment, or fires in

motors, switches, galley equipment,

etc., where a nonconducting

extinguisher agent is required.

NOTE: Whenever possible, electrical

equipment should be de-energized

before attacking a class C fire.

WARNING: THE WRONG EXTINGUISHER ON A FIRE COULD DO MORE HARM THAN GOOD. FOR

EXAMPLE,
