- Abstract
- Condensed-phase fire suppressing agents (eg. NaHCO3 particles and fine-water droplets) have been shown to be equally or more effective than the counterpart gaseous fire suppressing agents. Previous studies have also indicated that certain metallic compounds (eg. Fe(CO)5 and TiC14) are even more effective in suppressing laboratory scale flames. However, the toxicity associated with latter group of compounds has precluded their direct use in real fires. As part of this work, the concept of encapsulating such effective compounds safely within solid support particles and subsequent delivery to a flame for suppression is being investigated. The preliminary results of this effort will be presented. Another approach of enhancing the condensed-phase agents considered is the combination of thermal fire suppressing capabilities of water with chemical solvents. For example, addition of about 5% NaOH by mass to water and delivering it as a fine-mist is shown to reduce the mass of water-NaOH needed by a factor of 2.5. These results and other water-metallic compound solution flame suppression results will be presented.
