CAUTION: Do not use on electrical or grease-type fires.
Halon Fire Extinguishers
Halon fire extinguishers contain a liquified 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.
To use the Halon fire extinguisher, hold the extinguisher upright, and remove the
ringed safety pin. From a distance of 8 to 10 feet, aim the extinguisher nozzle at
the base of the flames and press the top lever.
WARNING: If a 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.

Systems Description
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.
Miscellaneous Emergency Equipment
Additional emergency equipment is stowed at strategic locations throughout the
airplane as shown in the Emergency Equipment diagram.
Emergency Locator Transmitters (ELTs)
ELTs are installed as shown in the Emergency Equipment diagram. ELTs transmit
when slide/rafts are deployed into water.
