A set of blends for extinguishment of fires, suppression of explosions, and inertion against fires and explosions is disclosed. The blends are comprised of a bromine-containing component and a fluorine-containing component. The bromine-containing component is comprised of one or more hydrobromoalkanes, hydrobromoalkenes, and/or hydrobromoarenes. The fluorine-containing component is comprised of one or more fluorine-containing halocarbons, which may also contain chlorine. Specifically provided as fluorine-containing halocarbons are saturated and unsaturated hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, perfluoroethers, hydrofluoroethers, and/or hydrofluoropolyethers. This provides a blend that mimics the fire and explosion protection action of halons and hydrobromofluorocarbons without the environmental impact associated with these compounds, which contain bromine and fluorine in the same molecule.

Cette invention se rapporte à un ensemble de mélanges conçus pour éteindre les incendies et empêcher les explosions, et pour limiter leurs effets. Ces mélanges comportent un composant contenant du brome et un composant contenant du fluor. Le composant contenant du brome est constitué d'un ou de plusieurs hydrobromoalcanes, hydrobromoalcènes et/ou hydrobromoarènes. Le composant contenant du fluor est constitué d'un ou de plusieurs halocarbures contenant du fluor et pouvant également contenir du chlore. Les halocarbures contenant du fluor sont notamment des hydrofluorocarbures, des perfluorocarbures, des perfluoroéthers, des hydrofluorocarbures, des hydrofluoropolyéthers et/ou des hydrochlorofluorocarbures saturés ou non saturés. Le mélange obtenu simule l'action des halons et des hydrobromofluorocarbures, s'agissant de la protection contre les incendies et les explosions, sans présenter les effets nuisibles sur l'environnement associés à ces composés qui contiennent du brome et du fluor dans la même molécule.
