Accidental discharge of the fire extinguisher could very easily cause severe
frostbite to body parts.
Small parts or tools laying around could become
dangerous flying projectiles when propelled by 750 psi of discharging Halon.
Be careful not to strike the bottles with objects or tools. When handling
the bottle, ensure they are not dropped or accidentally discharged.
When
performing maintenance or repair on any AFES, do not work alone.
Always
have one other person assisting you throughout the maintenance or repair
process.
WARNING
AFES is designed to provide 2 to 4 hours of fire
protection AFTER vehicle shutdown.
Turning MASTER
switch OFF does NOT deactivate AFES. Working on AFES
when active may cause serious injury to personnel.
2.
Deactivation.
The first step taken in the DEACTIVATION of the engine or crew AFES is to
turn the MAINTenance switch of the test and alarm panels to the OFF
(vertical) position.
A common flat-tip screwdriver is used to move the
switch to the appropriate position. The MAINTenance switch is to be used by
authorized organizational personnel or support maintenance personnel only.
Figure 10 provides an illustration of the T/A panels. The engine and crew
T/A panels are quite similar in appearance and perform a similar function.
Note that Item (1) in Figure 10 is the MAINTenance switch. The MAINTenance
switch has two positions, the horizontal position and the vertical position.
When the MAINTenance switch is in the horizontal position, power is being
supplied to the AFES.
When in the vertical position, the AFES is not
powered and maintenance can be accomplished.
With T/A panel switch is in
the vertical position, MASTER switch OFF, ensure all of the panel lights go
off to include the POWER ON light (Item 4, Figure 10). Disconnect battery
ground cables.
The second step in the AFES DEACTIVATION process is to move the ammunition
racks to the rear of the vehicle.
Ammunition racks are moved to provide
access to the fire extinguishers located on the front wall of the crew
compartment directly behind the projectile racks.
