Firebane 1115 and Firebane 1179 fire extinguishing agents were evaluated in scenarios typical of flight line fires. Undiluted Firebane has a freeze point below -20 F and is described as having low corrosion in brass and aluminum and acceptable corrosion in carbon steel and hot-dipped galvanized steel. Evaluations included JP-8 pool fires and three-dimensional JP-8 engine nacelle rear engine fires, which consisted of a 4-gal/min running fuel fire and 100-ft2 pool fire below the engine nacelle. The agents were assessed on extinguishment time, volume of agent used, and effectiveness on the fires. Compressed air foam systems were used for the evaluations, the recommended agent delivery method for Firebane. At full concentration neither Firebane 1115 or 1179 were effective at extinguishing rear engine fires. Firebane 1115 mixed 10 percent by volume with water was effective at extinguishing the simulated engine fire, and Firebane 1115 mixed 50 percent by volume with water was also effective on the engine fire but took more time and agent than the 10-percent mix. Firebane 1115 at full concentration and diluted 10 percent by volume with water extinguished JP-8 pool fires. |
