Abstract:
Replacements for the current commercial halons should
posses a diverse set of properties which are rarely
found together in the same molecule. Thus, the ideal
candidate for the replacement of halon 1301 would be a
nontoxic gas which is reactive in flames and in the
troposphere, yet at the same time, inert in the
stratosphere and in its storage environment. The
present generation of replacements, as typified by the
core candidates listed in Section 1, were selected on
the basis of a compromise, whereby fire suppression
efficiency was sacrificed to ensure acceptable
environmental properties. The research reported in this
section was directed at developing the capability to
predict the fire suppression effectiveness, propensity
to generate corrosive combustion products, and
environmental impact of a molecule on the basis of its
structure. This is essential to the development of a
rational approach to the search for new and more
effective fire fighting chemicals.
