1-15. Commissary Equipment. Commissary equipment provides for chilled and frozen
food storage, food preparation, food service, waste disposal, sanitation, and galley
exhaust and fire protection. Chilled and frozen food storage units are free-
standing refrigeration units. Food preparation units are freestanding steam kettle,
ranges, microwave ovens, fryers, and associated equipment. Food service units
include milk dispenser, coffee maker, and soft drink dispensing machine. Waste
disposal and sanitation are provided by a garbage disposal, solid waste compactor,
and dishwasher. The dishwasher and garbage disposal are connected to the ship's
sewage piping system. Galley air exhaust is provided by an exhaust hood tied to
ducting and galley exhaust fan which is part of the environmental control system.
1-16. Laundry Equipment. Laundry equipment is used by the LCU crew to wash, dry,
and maintain uniforms and linen. Laundry equipment consists of an electric
automatic washer, electric dryer, ironing board, clothes wringer, double sink, and
storage cabinet. The automatic washer and double sink drain to the ship's sewage
piping system.
1-17. Fire Fighting System. The fire fighting system provides fire stations and
specialized chemical fire suppression equipment throughout the vessel. The fire
fighting system consists of HALON fire suppression systems, foam proportioners, foam
tank, fire stations, fire monitors, fire fighting equipment, and washdown system.
The HALON system provides fire

suppression where highly flammable conditions exist. These areas are the main
engine room and paint locker room. The system extinguishes fires in these spaces by
actuated by pull cables or pneumatic actuators. Rate-of-rise temperature detectors,
when activated, set off an alarm in the pilothouse; however, the detectors do NOT
automatically start the HALON system. There is a 60-second delay during which the
siren sounds, warning personnel to evacuate the protected area. Pressure switches
interconnected with the electrical system of the LCU are activated during the delay
for ventilation equipment and lube/fuel oil pump shutdown. Upon discharge, the
HALON cylinders will release and flood the designated area in approximately 10
seconds.
b. Foam Proportioners . The fire fighting system has the capability of inducing
aqueous film forming foam (AFFF) into the fire monitors and foam stations. L i q u i d
AFFF is induced into the system via two AFFF three-way proportioners that provide
suction to the AFFF tank when water pressure is supplied from either fire pumps No.
1 or 2, auxiliary fire pump, or bilge/ballast pump through system alignment. The
system has the capability to discharge sufficient foam to cover the main deck
through fire monitors port and starboard (pilot house top), foam station 2
(pilothouse top) and foam station 1 (engine room) with 6 inches of foam. This foam
proportioning system can be aligned to supply seawater only, by closing the two AFFF
tank suction valves.
c. Fire Stations. Fire stations provide
seawater for fire suppression
throughout the ship. Fire stations consist
of fire plugs connected to the
bilge/ballast and fire main piping system.
Installed at each fire station is an
all-purpose nozzle with 50 feet of hose and
a spanner wrench.
