Optical Measurements of Toxic Gases Produced during Firefighting Using Halons
Several optical techniques Fourier transform infrared (FT-IR) emission and absorption spectroscopy, mid- and near-infrared tunable diode laser (MIR-TDL, NIR-TDL) absorption spectroscopy have been used to measure toxic gases produced during inhibition of flames by halogenated hydrocarbons (Halons). Fire types studied include low-pressure premixed flames, atmospheric-pressure counterflow diffusion flames, open-air JP-8 (turbine fuel) fires, and confined JP-8 fires. Spectra are presented and analyzed for these fires inhibited by CF3Br (Halon 1301) and C3F7H (FM-200). For real-scale fire testing, it is shown that type and amount of toxic gases produced during fire inhibition are highly dependent on fire conditions and temperatures, and that some species not considered important (CF2O) are often produced in significant amounts.
