Abstract:

Old style sprinkler deluge systems, discharging as much as 0.35 galminsq ft of Aqueous Film Forming Foam AFFF, have been found to be incapable of suppressing 900-sq ft JP-4 fires with 400-sq ft simulated wing obstructions rapidly enough to prevent structural damage to simulated aircraft in hangars. Two oscillating monitor nozzles, in combination with a 0.20 galminsq ft water deluge system, were tested on 100-sq ft pan fires of JP-4 at 50 and 100 psi, using three different AFFF agents. The application rate was approximately 0.1 galminsq ft. Both nozzles afforded equivalent performance. One of the three agents was found to require more than twice as much time to achieve control as the other two agents.
