 TM 55-1905-223-SDC
If the fire persists after expending two PKP extinguishers with little or no effect, low-velocity fog
should be used. Low-velocity water fog is superior to PKP on Class A and Class B fires.
6-18. AFFF. Aqueous Film Forming Foam (AFFF) is carried in 2-1/2 gallon, 28-pound portable
extinguishers. When fighting flammable liquid fires, aim the discharge at the base of the flame and apply it in
a slow, steady side-to- side sweeping motion so that the liquid overruns the fire surfaces, establishing and
maintaining the film that smothers the fire. After the film is established, do not break it by splashing the
stream on the film surface. In the case of a Class A fire, the stream should be pointed directly at the source of
the flames to penetrate and cool the fuel. The effective range of AFFF extinguisher discharge is 15 to 20 feet
from the nozzle to the base of the fire. The 695 gallon foam tank contains sufficient foam to cover the main
deck two times with 6 inches of foam.
Section IX. BASICS OF FIGHTING FIRE
6-19. GENERAL. While firefighting techniques cannot be set forth in any chronological pattern, the
following basic rules apply to nearly all situations:
a. Isolate the fire. Close all doors, hatches and vents, and secure blowers. All flammable liquid
system piping in the affected area should be isolated from damage control deck.
b. Shut down electrical circuits in the compartment where the fire is located and in adjacent spaces
to be sprayed or flooded.
c. Bring required firefighting equipment to the scene.
d. Lead out two hoses from different plugs, when practical, to the area of the fire; rig one hose with
an applicator, and charge both hoses.
e. Station a crewman with OBA, gloves, and head lamp, to control the nozzle for each of the two
separate hoses.
f. Station a backup crew member with OBA, electrically safe rubber gloves, and head lamp to relieve
the crewman on the nozzle or perform rescues.
g. Set fire boundaries in surrounding compartments and topside by rigging extra hoses to cool
decks, overheads and bulkheads, and by removing combustible materials.
h. Rig portable pumps which can be used if fire main pressure is lost.
i. Station crew members at arms room sprinkler controls.
J. Combat the fire from the best position possible to protect personnel; approach a topside fire from
windward, if possible. Consideration should also be given to approaching the fire from the bottom, if possible.
k. In compartments fully involved with fire, the firefighter should reduce the heat and flame before
entering by liberal application of water fog through doors and air ports into upper areas of the compartment. In
