- 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 0ºC) 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.
