Abstract

The recent ban on halon 1301 production (as a result of its ozone depleting potential) has resulted in an extensive search for replacements and alternatives. The applications of fire suppression efficiency screening methods constitute an important aspect of this search process because good screening methods can facilitate the identification, comparison, and selection of potential candidates for halon replacement. Most of the current methods for fire suppression efficiency screening (e.g., cup burners) are designed for evaluating fire suppressant agents that can be delivered in the form of vapor. Potential uses of liquid agents as replacements have been recently proposed in several applications (e.g., shipboard machinery spaces, engine compartments in armored vehicles). Therefore, there is a need for the development of a reliable screening method for liquid agents that can be delivered in droplet form. The objective of our work is to design, construct, and demonstrate a laboratory-scale apparatus to screen liquid agents in a well-controlled experimental setting.
