A coaxial turbulent spray burner was used to determine
the suppression characteristics of twelve different fire
fighting agents in elevated temperature hydraulic fluid
and jet fuel (JP-8) spray flames. The effectiveness of
the gaseous agents, being considered as alternatives to
halon 1301, was compared based upon the mass required
for suppression and the equivalent storage volume,
normalized by the amount of halon 1301 required to
suppress the flame. The elevated temperature results
were compared to measurements previously obtained with
the incoming air and JP-8 at ambient temperature. No
statistically significant difference in relative agent
performance was found between the heated hydraulic flame
and the previous JP-8 experiments. There was a trend
toward higher agent concentrations when the fuel was
JP-8 and the temperature of the incoming reactants was
150 deg C. In all three experiments, the halon 1301
required the least mass to extinguish the flame,
followed by nitrogen. The rest of the alternative
fluorinated agents considered required between 1.2 and
2.4 times more mass to suppress the various flames.
