a means is required to identify and assure control of
inspection cycle. To accomplish this, all portable, hand-
operated fire extinguishers intended for use in Army
aircraft will be tagged as follows:
All serviceable fire extinguishers installed in
aircraft will have a DD Form 1574 (Serviceable
Tag Materiel) attached. The DD Form 1574 will
show next inspection due, as stated in DA PAM
738-751.
Fire extinguishers are considered unserviceable
if the gross weight stamped on data ring, as
shown in figure 2-3, is not legible or the data
ring is missing.
Fire extinguishers determined unserviceable or
requiring a scheduled inspection will be replaced
with a serviceable fire extinguisher, tagged with
a DD Form 1574.
Fire extinguishers received through supply
channels that are in original manufacturer's
packaging and show no evidence of damage
shall be considered serviceable and will be
tagged accordingly, prior to installation in
aircraft.
(6)
Location of fire extinguishers. Fire extinguishers
shall be located throughout the shop in readily
accessible areas.
(7)
Marking of fire lanes. Fire lanes shall be
marked and kept clear for emergency personnel should
