- Abstract
- This project evaluated the performance of a precision metering system for the P-19 firefighting vehicle and the effectiveness of 1 percent AFFF in fighting large hydrocarbon fires. The metering system was designed, manufactured, installed, and test assistance provided by the Hypro Corporation. This system replaces the around-the-pump inductor foam metering system, originally installed in the P-19, with a modern closed-loop computer-controlled system. The Hypro metering system is a well engineered; metering accuracy is excellent. The primary nozzles of the P-19, roof and bumper turrets, maintain metering at either 1 or 3 percent within the specified tolerance of ±0.1 for 1 percent and ±0.3 percent. One percent AFFF was found to be at least as effective and possibly more effective, than 3 percent AFFF in extinguishing large JP-4 fires.
