Live Fire Evaluation of the Expeditionary Fire Suppression System (EFSS); Phase I

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 system uses AFFF-based compressed air foam and PKP dry chemical. Phase I evaluated the effectiveness of the modified-commercially available EFSS on live fires on static pool and running fuel fires. The EFSS performed well in the live fire evaluations conducted at Tyndall AFB, FL. The system consistently showed the capability to extinguish both pool and running fuel fires. Several minor problems were encountered with the system but were quickly resolved by the manufacturer and the equipment was put back into service. Issues with the filters, switch covers and the additional capacity on the high pressure air will need to be addressed by the manufacturer in subsequent units.
