A water spray mist is used to cool a compartment fire before discharge of a gaseous fire suppression. As a result, less water and less fire suppression agent is needed than required with conventional method of suppressing compartment fires. The water spray may be continued for a short time after initial discharge of the fire suppression agent, and may be restarted after the fire has been extinguished. Also, the present invention reduces the levels of toxic and corrosive gases in compartment created during the suppression of compartment fires by the use of a gaseous fire suppression agent.

[ What is claimed is:] [1.] A method of suppressing fire within a compartment, comprising the steps of:spraying, at a pressure of no more than about 150 psi and before introducing a gaseous fire suppression agent into said compartment, water onto a fire in said compartment, in an amount sufficient to cool the ambient temperature in said compartment to below 100.degree. C., but no greater than the amount required to cool said ambient compartment temperature to 200.degree. C., thus forming a cooled compartment;introducing a gaseous fire suppression agent into said cooled compartment, in an amount sufficient to extinguish said compartment fire.
