St. Louis Gets Crash Truck
A crash buck that can apply about 22,500 gallons of foam in less than 2 minutes is the newest addition to the file fighting facilities maintained by the St. Louis Fire Department at the Municipal Airport. The P-2 is a Seagrave-FWD civilian version of a type of crash truck developed by the Air Force in 1963 to protect large aircraft at Strategic Air Command bases.
Almost everything about the 67,000-pound P-2 is of outsize proportion. For example, its overall dimensions are: length, 35 feet; width, 8 feet 8 inches; and height, 11 feet 6 1/2 inches. The wheels are almost 6 feet high.
When both its 340-hp engines are engaged for propulsion, the truck can accelerate from a standstill to 55 mph in less than 60 seconds. Driver-controlled TractionLocks in all axle and transfer differentials eliminate differential action and give the vehicle maximum ability for reaching a fire under the most adverse ground conditions.
When the fire scene is reached, one of the engines powers a 1,400-gpm, single-stage, centrifugal pump to provide a pressure of about 200 psi at the two turret nozzles for generating foam. The crash truck’s tanks hold 2,300 gallons of water and 200 gallons of foam concentrate. This is enough to produce approximately 22,500 gallons of foam.
The vehicle will operate in temperatures ranging from extreme heat down to —65 °F. A winterization kit that is available includes a gasoline fluid heater of 90,000 Btu—large enough to heat a six-room house. In addition, an air conditioner can keep the cab at a comfortable working temperature in extreme heat conditions.
