Effect of Suppressants on Metal Fires

摘要

The present study is limited to examining the effect of the vapors of varioushalogen-containing suppressants on the burning of pure magnesium and titanium rods in a slow flow of oxygen-containing gas. The test configuration was instrumented to allow quantitation of the effect of the vapors on the rate of burning. The agents examined in the presence of burning magnesium included halon 1301 (the reference case), HFC-125, HFC-227ea, FC-218 and CF3I. For titanium, time limitations narrowed the study to halon 1301, HFC-227ea(sup 2) and HFC-125.
