Environmental concerns related to the destruction of
stratospheric ozone has initiated the phasing out of the
ubiquitous fire-fighting agent Halon 1301 (CF3Br) from
the U.S. Army inventory. 2-H heptafluoropropane (C3F7H,
FM-200, HFC-227ea) has been identified as one of the
alternative agents for unoccupied spaces of critical
installations formerly protected by Halon 1301. For
occupied spaces, where fires must be suppressed in a
short period of time (250 ms), to minimize exposure to
extreme heat and toxic fumes, a mixture of C3F7H with
sodium bicarbonate (NaHCO3) or water with potassium
acetate has been chosen as a leading halon replacement
