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.
Inertia Reels
Inertia 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. They are
used to lower the flight deck occupants to the ground during emergency egress
through the flight deck overhead door. (Refer to Flight Deck Overhead Door
in
Chapter 1, Section 40, for additional information.)
Fire Extinguishers
Halon and water fire extinguishers are located throughout the passenger cabin. A
Halon extinguisher is also located 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
and use 100% oxygen with emergency selected.
CAUTION: For electrical fires, remove the power source as soon as
possible. Avoid discharging directly on persons due to
possibility of suffocating effects. Do not discharge too close to
fire as the discharge stream may scatter the fire. As with any
fire, keep away from the fuel source. Avoid breathing vapors,
fumes and heated smoke as much as possible.
