Abstract:
Due to its ozone-depleting potential, halon 1301 (CF3Br)
has been banned from production under the Montreal
Protocol. The research for halon replacement(s) has led
to the reconsideration of using water in certain
applications. However, under cold storage conditions
(below 0DGC) water will freeze, thus posing a limitation
in low temperature operations. Certain additives, if
selected properly, not only can suppress the freezing
point of water but also can improve its fire suppression
effectiveness. Some water-based agents have recently
been proven to be more effective than pure water when
used in the form of mist to suppress a small JP-8 pool
fire. Among the thirteen agents they tested, potassium
lactate (60% w/w) and potassium acetate (60% w/w) were
found to be far superior than pure water and other
candidate solutions.
