Abstract:

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 candidate.
