under the cab. The reel is provided with 150 feet of
1 1/4-inch-diameter hose. The handline has a 75 to 100
gpm discharge capacity. An air motor provides for
powered rewind. Four 30-pound PKP dry-chemical
fire extinguishers are provided with each vehicle.
When both the roof turret (750 gpm) and the bumper
turret (250 gpm) are operating, the truck depletes its
self-contained water supply in 1 1/2 minutes.
P-19 FIRE FIGHTING
TRUCK
The P-19 has a diesel-engine-powered, 4 × 4,
all-wheel-drive chassis. A single diesel engine powers
the truck drive train and water pump. The fire-fighting
systems of the truck are self-sufficient.
No outside
source for extinguishing agents is needed. The truck
contains its own pressure pumps and fire-fighting
equipment. Water, foam, and Halon 1211 are carried in
tanks built into the truck body.
The truck body is
insulated, which prevents heat loss from the truck's
interior during cold weather.
The insulation also
provides protection from fire heat.
Water or a combination of water and foam can be
used to put out a fire. Agents are delivered through the
cab-mounted roof turret, the bumper turret, or the
handline. These can be used alone or at the same time.
The Halon system uses its own handline. The chassis
design allows the truck to operate in all kinds of
weather and on off-road terrain.
The P-19 has a water capacity of 1,000 gallons, and
the foam tank holds 130 gallons. The single-roof turret
has a discharge capacity of 500 gpm, and the bumper
turret discharges agent at 250 gpm.
AFFF can be applied by using a 100-foot,
1-inch-diameter (60-gpm), reel-mounted handline.
Five hundred pounds of Halon 1211 is also available on
another 100-foot-long, 1-inch-diameter, reel-mounted
handline.
