Abstract

Heptafluoropropane is one of the clean agents substituted for Halon for use in gas protection systems. The design concentration with respect to a particular fuel is an important parameter in the system design and will be studied in this article. Current standard requirements for the protection of Class B fires with the clean agent are briefly reviewed. The minimum design concentration will be measured by the cup burner test. Agents were tested on extinguishing fires from three liquid fuels - propanol, petrol, and kerosene. Two different sizes of cups and chimneys are used. The results on heptafluoropropane are compared with two other gaseous extinguishing agents - carbon dioxide and Inergen. This study confirms that the required amount of heptafluoropropane for extinguishing the above three fires is much smaller than the other two agents tested.
