Abstract
We investigate the rationale for the use of CF,Br as a reference standard for alternative fire suppresants. Stating efficiencies of alternative agents on a relative basis to that of CF,Br is well founded from an engineering standpoint, but less so from a mechanistic standpoint. The behavior of CF,Br is, in several significant respects, atypical of fire suppressants, which act by catalytic scavenging of flame radicals. In particular, saturation effects, dependence of inhibition efficiency on flame temperature, and changes in flame structure are significantly different for CF,Br than for other catalytic substances including iron and alkali metals. For this reason, the use of CF,Br as an archetype for catalytic suppressants must be qualified to account for these differences.Citation
