Section II. EQUIPMENT DESCRIPTION
1-6. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
a.
CHARACTERISTICS. The Fire Suppression Equipment Set is skid mounted and attached to a wheeled trailer
that can be easily relocated when necessary. It is equipped with two fire fighting agents designed to be effective In
fighting fires generated by hydrocarbon fuels. These agents are a dry chemical and an Aqueous Film Forming Foam
(AFFF). The dry chemical extinguishes fires by breaking up flame propagation, and is compatible with mechanical foam
Water mixed with the Aqueous Film Forming Foam agent concentrate forms a foam which is then used to form a film
over the extinguished area, preventing re-ignition. These two agents are stored m containers on the Fire Suppression
Equipment Set, making the unit self-contained.
b.
CAPABILITIES. The Fire Suppression Equipment Set has the capability of extinguishing a fire from a 20,000
gallon (75,160 liter) tank of 100/130 aviation gas in a 1500 square foot (139 square meter) berm (diked area). A 150-foot
(46-meter), non-collapsible hose and discharge nozzle is provided for dispersing the chemical agents. An Auxiliary
mobile hose reel cart is provided with a second hose reel of 150-feet (46 meters) that can be connected to the end of the
hose from the unit to provide additional area coverage without moving the entire Fire Suppression Equipment Set.
c.
FEATURES. The unit is built for rugged use and is treated with corrosion resisting coatings making It extremely
durable over a wide range of climatic conditions. The chemical agents discharge hoses are encased in a single cover for
convenient storage and use and are linked by a tie bar at the nozzles. The hose Is stored on a hose reel at the front of
the unit when not m use. The hose ends and nozzles are equipped with quick-disconnect fittings which allow rapid
connection of the auxiliary cart The skid mounted Fire Suppression Equipment Set can be un-bolted from the wheeled
trailer and removed. A lifting bar is provided to lift the unit from the cart and slots are provided for lifting with a fork-lift.
Tiedown eyes are provided to anchor the unit and cart to a truck-bed or aircraft floor. The Fire Suppression Equipment
Set can operate down to -40° F (-40° C) by using an electric heater around the AFFF tank to keep the water mixed
solution from freezing.
d.
LIMITATION. At least two, and preferably three highly skilled operators are required to fight a berm fire with this
equipment, one manning the nozzle and the others to assist In dragging and maneuvering the hoses or replacing the
nozzle operator if necessary. The unit has only a 40-50 foot (12-15 meter) range requiring close-in position and therefore
it is mandatory that all operating personnel wear protective clothing.
