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
