||Fire research has shown that combustion can be prevented by increasing the heat capacity of the atmosphere. This can be effected by addition to the air of perfluorocarbons such as carbon tetrafluoride (CF4), hexafluoroethane (C2F6) and octafluoropropane (C3F8), which being physiologically inert permit life to be sustained; they can also be used to extinguish existing fires. On account of the production of toxic decomposition products by C2F6 and C3F8, however, only CF4 appears acceptable from the toxicity standpoint for use in habitable atmospheres.
