This project is an investigation of advanced fire suppression agents as replacements for Halon 1211 used in U.S. Air Force flightline and aircraft portable fire extinguishers. Materials tested in this test series emphasized agent blends containing bromoalkanes. Baseline tests were run with Halon 1211. The testing took into account agent discharge patterns, flow rates, wind conditions and technique, and allowed comparison of agent effectiveness to that of Halon 1211. Blends of small amounts up to 24 weight percent of 1-bromopropane in a hydrofluoropolyether showed enhanced fire extinguishment performance over that of either of the pure components. Similar enhancement was seen with HFC-23fa and 1-bromopropane. Results were compared to those obtained in similar testing performed for the U.S. Army.
