Abstract:
1. A method for an environmentally safe testing of a foam delivery system on a fire fighting vehicle, comprising: providing a mobile platform adapted for movement to a location having said fire fighting vehicle, said mobile platform including a surrogate fluid storage tank and a first ball valve pipingly connected to said surrogate fluid storage tank, said surrogate fluid storage tank housing an environmentally safe surrogate fluid; transporting said mobile platform to the location of said fire fighting vehicle to conduct a test of the foam delivery system on said fire fighting vehicle; connecting one end of a first flexible hose to an outlet port of said first ball valve; connecting an opposite end of said first flexible hose to a first port of a first universal adapter; connecting a second port of said first universal adapter fitting to a fitting connector pipingly connected to a drain valve having a first inlet/outlet port and a second inlet/outlet port; closing an isolation valve located on said fire fighting vehicle to prevent Aqueous Film Forming Foam (AFFF) from a foam tank on said fire fighting vehicle from passing through a second ball valve into the foam delivery system on said fire fighting vehicle; allowing said surrogate fluid to flow from said surrogate fluid storage tank into the foam delivery system on said fire fighting vehicle by opening said first ball valve, said drain valve, and said second ball valve; controlling a flow rate of said surrogate fluid through said foam delivery system, the flow rate of said surrogate fluid through said foam delivery system being controlled by a metering valve pipingly connected to said second ball valve on said fire fighting vehicle, wherein said second ball valve is pipingly located down line of a third end of a T, wherein a first end of said T is connected to said foam tank and a second end of said T is connected to said first inlet/outlet port of said drain valve; providing an environmentally safe pressurized liquid to the foam delivery system on said fire fighting vehicle; mixing said surrogate fluid with said pressurized liquid to form a surrogate fluid mixture under pressure, said surrogate fluid mixture being formed by an eductor located on said fire fighting vehicle and connected to said metering valve; providing said surrogate fluid mixture to a plurality of nozzles located on said fire fighting vehicle under pressure testing each of said plurality of nozzles with said surrogate fluid mixture; and measuring the flow rate of said surrogate fluid from said surrogate fluid storage tank with a flow sensor located on said mobile platform.
