Abstract: A portable fire fighting apparatus has a plurality of tanks containing a variety of fire fighting agents, a piping arrangement for selectively connecting the tanks to respective discharge nozzles, and a central control panel which is provided with a plurality of control valves and elements for selectively controlling the discharge of the fire extinguishing agents through the nozzles. In a preferred embodiment, the apparatus has three tanks containing water, a chemical fire extinguishing agent, and a foam concentrate, respectively. Water only or a water/foam concentrate mixture is controllably discharged through a first nozzle, while the chemical fire extinguishing agent may be separately or simultaneously discharged through a second nozzle. A piping arrangement for purging the nozzles following discharge is provided and is controllable from the central control panel. The apparatus may be adapted for mounting on a truck, a forklift, or other vehicle.
