Investigation of the Feasibility of Synergistic Enhancement of Halogenated Fire Extinguishants

摘要

The report presents results of a program to test the feasibility of synergistically enhancing the effect of halogenated fire extinguishants with addition of free radical initiators. Data are presented from screening for the synergistic enhancement effect by means of 1) flame speed measurements of hydrogen-air flames to which initiator-inhibitor mixtures are added, 2) flammability limits of heptane-air flames to which initiatorinhibitor mixtures are added, and 3) small scale pan fire tests using initiator-extinguishant mixtures. Results of the experimental program are discussed and attempts made to relate observations to known combustion phenomena. (Author)
