1.45 Airplane General, Emergency Equipment, Doors, Windows-Emergency Equipment Introduction
Emergency equipment described in this chapter includes:
• emergency evacuation signal system
• emergency locator transmitters (ELTs)
• escape reels
• fire extinguishers
• portable flight deck emergency equipment locations
• portable passenger cabin emergency equipment locations.
Emergency Evacuation Signal System
The emergency evacuation signal system alerts the flight attendants to evacuate
the passenger cabin. Evacuation command switches are located on the flight deck
and at the flight attendant panels.
Placing the flight deck EVAC COMMAND switch to ON activates the evacuation
signals on the flight deck and on the flight attendant panels. With the flight deck
EVAC COMMAND switch in ARM, pressing an EVAC COMMAND switch on
a flight attendant panel will activate the evacuation signals on the flight deck and
on the flight attendant panels. With the flight deck EVAC COMMAND switch in
the OFF position, all emergency evacuation panels are disabled.
Emergency Locator Transmitter (ELT)
Passenger Cabin
ELTs are installed in the passenger cabin, as shown in the Emergency Equipment
Locations – Passenger Cabin diagram.
Two emergency locator transmitters are installed:
• one in the lavatory outboard stowage at door 1L
• one in the lavatory outboard stowage at door 4R.
Fuselage Mounted Emergency Locator Transmitter (ELT)
An ELT is mounted to the top of the fuselage in the passenger cabin area.
The ELT automatically transmits distress signals on 121.5 MHZ, 243 MHZ, and
406 MHZ if a deceleration is sensed, or if the ELT switch is positioned to ON.
The EICAS alert message ELT ON is displayed if the transmitter is activated. The
ELT can be deactivated by placing the ELT switch to RESET momentarily, then
ARMED.

Escape Reels
Escape reels are attached to the airplane structure in the flight deck ceiling. The
reels are stowed in a compartment near the flight deck overhead door.
Fire Extinguishers
Halon and water fire extinguishers are located throughout the passenger cabin and
on the flight deck.
Halon Fire Extinguishers
Halon fire extinguishers contain a liquefied gas agent under pressure. The
extinguisher pressure indicator shows three pressure ranges:
• acceptable
• recharge
• overcharged.
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 is used primarily on electrical,
fuel, and grease fires.
WARNING: If a halon fire extinguisher is to be discharged in the flight
deck area, all flight crew members must wear oxygen masks
