| 摘要： | In the winter of 2002, the Halon 1211 flight line extinguisher was evaluated for fire fighting effectiveness by a standard protocol developed at the Air Force Research Laboratory for engine nacelle fires. The extinguisher was found to be 90 effective at extinguishing fires in ambient temperatures ranging from 44 degrees to 77 degrees F. In 2007, extinguishing agents selected as potential replacements for Halon 1211 were evaluated under the same protocol. Results of those evaluations called into question the effectiveness of Halon 1211 at higher ambient temperatures. Five additional fires were done with the Halon 1211 flight line extinguishers in October and November 2007 at temperatures of 78 degrees to 85 degrees F. All five fires were extinguished in an average time of 18 s, and required an average of 61 lbs of Halon. These results were commensurate with results from the original series of evaluations done in 2002. |
