- Abstract
- Results were summarized from Bureau of Mines studies on the effectiveness of halogenated agents as fire and explosion suppressants and on the limitations of a commercial Halon 1301 extinguisher for use as an ignition-quenching device. Halons containing bromine tend to be more effective than those without bromine in inerting hydrocarbon-air mixtures; the Halon 1301 requirement for inerting methane-air mixtures was greater than that report in NFPA literature. Dispersion experiments revealed that extinguishment failures in the mine tests were attributable to nonuniform agent distribution which resulted in the formation of voids with very low agent concentrations.
