PORTABLE FIRE EXTINGUISHING - DESCRIPTION AND OPERATION
_______________________________________________________
1. General_______
A. Portable fire extinguishers are installed in several general locations in the passenger compartment. If the extinguisher is not easy to see, the location will be identified with a placard. The extinguishers are usually installed in one or more of these areas: galley or lavatory stowage areas, closets, doghouses, or near attendant seats. A fire extinguisher is also installed in the flight compartment.
B. The portable extinguishers are attached to wall-mounted brackets by quick-release mounting straps.
2. Component Details (Fig. 1)_________________
A. Halon Extinguishers
(1)
Halon extinguishers are used to extinguish electrical and flammable liquid fires.
(2)
The halon extinguisher is rechargeable. A pressure gage shows when you must recharge or replace the fire extinguisher.
(3)
To operate the extinguisher, pull the handle locking pin. Hold the extinguisher upright and squeeze the handle and lever together. Point the nozzle flow at the base of the fire. The halon extinguishing agent leaves no residue after discharge.
B. Pressurized Water Extinguishers
(1)
Pressurized water extinguishers are used to extinguish nonelectrical fires.
(2)
The water extinguisher is rechargeable. An antifreeze is added to the water to prevent freezing.
(3)
A carbon dioxide cartridge is mounted on the handle of the extinguisher. To operate the extinguisher, turn the cartridge. This punctures the cartridge and pressurizes the water container. Push the trigger and aim the nozzle flow at the base of the fire.
