APPENDIX A
Section III. DEMOLITION TO PREVENT ENEMY USE
A 1-14. GENERAL. When capture or abandonment of the model 450PKP/ 100AFFF03638MC fire extinguisher to an
enemy is imminent, the responsible unit commander must make the decision to either destroy the equipment or to render
it inoperative. Based on this decision, orders are issued which cover the desired extent of destruction.
A 1-15. DEMOLITION TO RENDER THE FIRE EXTINGUISHER INOPERATIVE.
a.
Demolition by Mechanical Means. Mechanically demolish the extinguisher as follows:
(1)
Open nitrogen cylinder valves and hose nozzles and discharge agents.
(2)
Use fire axes, hammers, pry bars, pickaxes, or similar tools to:
(a)
Sever twin handlines in several places.
(b)
Sever high pressure hoses from nitrogen cylinders.
(c)
Sever low pressure lines in all accessible areas.
(d)
Destruct nitrogen pressure regulators.
(e)
Destruct and/or break off all pressure relief valves.
(f)
Empty all AFFF and dry chemical containers in the area.
b.
Demolition by Misuse. The fire extinguisher's safety devices, coupled with its rugged design, effectively preclude
any extensive damage by misuse.
A 1-16. DEMOLITION BY EXPLOSIVES OR WEAPON FIRE.
a.
Demolition by Explosives. The fire extinguisher can be effectively rendered inoperative without use of
explosives.
b.
Demolition by Weapons Fire. Small arms weapon fire can be effectively used to:
(1)
Destruct pressure regulators, manifold lines, hoses and hose reels.
(2)
Deplete nitrogen supply by destroying cylinder gages.
(3)
Render most valves inoperative.
(4)
Render nozzles inoperative.
(5)
The thickness of the AFFF and dry chemical container walls, combined with their mostly curved surfaces,
makes it unlikely that small arms fire would be effective in destroying. It is recommended that .50 caliber weapons and
armor-piercing ammunition be used for this purpose, guarding against possible ricochets.
A 1-17. DEMOLITION BY SCATTERING AND CONCEALING PARTS . The fire extinguisher can be rendered
inoperative quickly and easily by removing several components or parts. These parts are small enough to be easily
carried and disposed of by hiding, burying, or submerging in bodies of water. After depleting the nitrogen supply by
opening the nitrogen cylinder valves and hose nozzles, dispose of the following easily removed components, or parts:
