SYSTEM (AFES/MDS) COMPONENTS - Continued
Vehicles 345 And Above
1 - 10-lb Fire Extinguisher
2 - 7-lb Fire Extinguishers
The fire extinguishers consist of steel cylinders filled with Halon 1301 and equipped
with a quick-release valve assembly.
The cylinders contain HaIon fire suppressant pressurized with dry nitrogen for use on
hydrocarbon fuel fires only.
The AFES/MDS has three fire extinguishers. The one for engine fires can only be acti-
vated by using the lanyard cable pull handle. The other two AFES/MDS fire extin-
guishers, located in the crew compartment, can also be activated automatically by the
SCEA or by activating the MANUAL ELECTRIC DISCHARGE toggle switch.
All fire extinguishers will not activate at the same time when a crew member pulls the
lanyard cable pull handle located near the drivers hatch on the outside of the vehicle.
Handle must be pulled to fullest extension to discharge extinguishers.
Two portable CF3BR (monobromotrifluoromethane) fire extinguishers
are also located in the crew compartment and are separate from the
AFES. These portable fire extinguishers may be used as needed on fuel
and electrical fires. One portable fire extinguisher is located on the lower
rear door and the second is located on the right side rear canister rack.
