Thermal breakdown of extinguishing agents

Abstract
Four fire extinguishing agents has been investigated, bromotrifluoromethane, Halon

1301, pentafluoroethane, HFC 125, heptafluoropropane, HFC 227ea and dodecafluoro-2-

methylpentane-3-one, C6F-ketone. The inerting concentrations were determined in a cubic

pressure vessel with a volume of 8 litres. A cup burner was used to find the flameextinguishing

concentrations for the agents. Thermal breakdown was also studied and for

this purpose the studied agent was introduced into a flame of propane in a tubular burner.

The produced combustion products were analysed both with conventional IR-techniques

and with FTIR. It was found that HF and COF2 were produced from all studied... (More)
