Abstract:

An experimental program was conducted wherein mixtures of two fire suppressing agents, and a gelling agent bromotrifluoromethane, CBrF3, ammonium dihydrogen phosphate ADP and Cab-O-Sil were prepared as a potential suppressing agent for habitable aircraft interiors. These mixtures, although capable of extinguishing a combination class A and B fire, yielded a large quantity of particulates causing a high degree of obscuration and were, therefore, considered unsuitable for this application. A mixture of Halon 2402, ADP and Cab-O-Sil was prepared and found to be an excellent suppressing agent against the combination class A and B fire. This agent may be suitable for this application after certain toxicological questions are resolved. Author
