EMERGENCY EQUIPMENT
INTRODUCTION
Today’s technology has enabled aircraft manufacturers to build larger, better and more
reliable aircraft. Even as on board emergencies such as fires, rapid decompression,
ditching or emergency evacuations become unlikely, it remains important that aircraft
be equipped with the proper emergency equipment and that the crew be cognizant of
the equipment available and its proper functioning.
This chapter will introduce the standard emergency equipment available on the
Global. It is important to note that each Global will differ in the location of this
equipment. It is essential that the crew brief new members as well as passengers on
safety procedures to ensure the maximum safety during flight.
This emergency equipment includes:
• Emergency locator transmitter
• Evacuation devices (exits, crash axe)
• Exit lighting
• Fire fighting equipment (portable fire extinguisher)
• First aid kits (MEDAIR)
• Oxygen equipment (fixed and portable)
• Over water emergency equipment (life vests, life rafts)
Aircrew must refer to their Aircraft Operating Manual for the use of Completion
Center installed items.
Data on airplane doors and emergency exits is contained in Chapter 1, AIRPLANE
GENERAL. Data on the emergency lighting system is contained in Chapter 15,
LIGHTING.

DESCRIPTION
This chapter describes the systems and equipment which are essential to the safety of
passengers and crew during a fire, rapid decompression, ditching and emergency
evacuation. These include the following equipment:
• Oxygen equipment (portable and fixed)
• Evacuation devices (crash axe, emergency lighting and emergency exits)
• Fire fighting equipment (portable and fixed)
• Over water emergency equipment (life vests)

OXYGEN
A gaseous oxygen system is supplied by four cylinders to serve the flight crew and
passengers.
FLIGHT COMPARTMENT
The flight compartment oxygen consists of the following:
• Four oxygen bottles (with a pressure regulator unit, bottle gauge, and shutoff
valve)
• Ground servicing panel (with a gauge and filler valve)
• Fuselage-mounted overboard relief valve (frangible disc)
• Two oxygen mask/regulator units and goggles

OXYGEN BOTTLE
The oxygen bottles [1418 liter (50.1 cubic feet)] are located in the forward fuselage
underfloor area. Normal charge pressure at 21°C (70°F) is 1850 psi.
Charge pressure is indicated as follows:
• Gauge on the bottle shutoff valve
• Gauge on the ground servicing panel
• Oxygen quantity is indicated on the EICAS status page
When bottle pressure becomes excessive, approximately 2600 psi, all oxygen is
vented overboard by a pressure regulator unit working in conjunction with a fuselagemounted
relief valve. Overpressure causes the OXY HP RELIEF disc, located on the
left front fuselage, to blow out.
The pressure regulator unit regulates flow to the crew mask regulator unit to 72.5 psi
and the unit’s strain gauge transmits pressure signals to EICAS.
The crew mask/regulator unit regulates the flow to the crew masks. Oxygen is
supplied via the regulator at either ambient or slightly over ambient pressure
