Evaluation of the TRIMAX 280 System

Evaluations of the TRIMAX 280 were conducted to determine its suitability for use by Marine Corps personnel in support of forward deployed units; specifically, MOS 7051, Aircraft Rescue and Firefighting Specialists with the primary mission of rescue and fire suppression during aviation related incidents. This test series evaluated the TRIMAX 280 for fire fighting operational adequacy and overall system performance using fixed orifice and variable stream nozzles with compressed air foam. A series of five JP-8 pool fires of 2500-sq ft, three JP-8 3500-sq ft pool fires with F100 engine nacelle mockup, and one JP-8 700-sq ft with F100 engine nacelle mockup were used to evaluate the 90% control and full extinguishment times. System operation was evaluated by conducting tests for throw distance, agent duration, agent stream decay, agent flow rate, expansion ratio and 25% drainage time. The TRIMAX 280 controlled and extinguished all but one of nine fires. The first 3500-sq ft fire attempted was not extinguished prior to agent depletion. System evaluation showed no performance inadequacies. The original document contains color images.
