Abstract:
An international consensus to remove Chlorofluorocarbon CFC compounds from production and U.S. national policy to implement the resulting protocols has motivated the U.S. Air Force to embark on a program to find a suitable replacement for Halon 1211, currently used to extinguish flight line fires. This research addressed the feasibility of conducting a combustion toxicology CT program to assess the toxic products of the combustion interaction of JP-8 and the Group 1 or so-called Near Term candidate replacement agents for Halon 1211 HCFCs -123, -124, and -142b. A laboratory scale experiment benchmarked on large scale testing of a 150 sq ft pool fire was developed on the basis of Froude scaling of the full scale fire to a 15 x 15 cm pan fire. A prototype apparatus was developed and investigation into the use of animal behavior methods as an indicator of human incapacitation was conducted. The result is a new method which may potentially be utilized for future toxicity studies of the combustion interaction of current and future U.S. Air Force fuels with various fire extinguishants.
