Performance Effectiveness Testing of the Expeditionary Fire Suppression System. Phase II
Abstract
On behalf of AAC/WMO, the Air Force Research Laboratory evaluated the Expeditionary Fire Suppression System (EFSS). The EFSS is a modified-commercial, combined-agent system that can be mounted on an Air Force P-20 truck or heavy duty, general purpose truck. The preliminary tests and evaluations of the EFSS 5120-7 to determine its effectiveness included foam and dry chemical flow rates; foam throw distance and foam expansion ratio. The overall performance of the EFSS was good. Expansion ratio, throw distance and flow rates were all within acceptable ranges. The majority of the problems experienced with the EFSS 5120-7 were a result of the regulators, which could easily be resolved with filter to remove debris from the compressed air. The foam system needs to be evaluated to determine why that part of the system is activated when the dry chemical system is being discharged. The dry chemical system is performing less than optimal, with approximately 50% of the total dry chemical volume not being discharged with the given volume of compressed air.
