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 agents.
Models and theories on the mechanisms of the breakdown processes are presented.
