A fire fighting apparatus for confining a fire to an immediate area defined by a plurality of fire retardant curtains which are dropped from container cabinets upon actuation of a release mechanism which may be triggered manually or coincidentally with the actuation of a fire extinguishing device associated with the mechanism to be patented. In a preferred form, a plurality of fire retardant curtains are stored in a plurality of modular cabinets which are suspended from a ceiling covering the area to be protected. The release mechanism which allows the curtains to drop from one cabinet is connected to the release mechanism of adjacent cabinets for simultaneous operation of all associated cabinets. In use, operation of an automatically actuated fire extinguishing system, such as discharge of carbon dioxide to the area to be protected, causes a gas pressure drop serving to actuate the trigger mechanism which allows each door lock to move toward a released position to which it is normally biased. In the extended position, the curtains have their edges disposed adjacent one another so as not only to confine the extinguishing gas to a desired area but also to permit workers to escape through the curtains or fire fighting personnel to enter therethrough.
