ABSTRACT OF THE DISCLOSURE A system for use in a building for venting a fire with- in the building. When a fire starts within a section of a high- rise building, smoke can spread throughout the building, or at least throughout an area of the building, and can cause a panic. In order to permit the escape of smoke, the practice has been for firemen to break windows of the existing structure in order to vent the fire, thus allowing it to quickly burn out while dissipating the smoke generating from the smouldering fire. Since the breaking of windows necessarily involves some danger and the clearing of people away from the immediate area before the windows are broken, there is a loss of time before venting can take place. Further, the breaking of the windows necessi- tates their replacement. Accordingly, the present invention provides a system for venting a building, the system comprising a first vent disposed at one floor of the building and including a fixed frame, a movable frame adapted to fit within the fixed frame when in a closed position, and panel means for insertion into the movable frame. The system also comprises means for pivotally securing the movable frame to the fixed frame, means for securing the movable frame to an open position, and latch means for maintaining the movable frame in the closed position. A first release member is provided for releasing the latch means of the first vent to permit the movable frame to open to its open position. A second vent is disposed at another floor of the building and includes a fixed frame, a movable frame and a latch means. A second release member is disposed remote from the second vent for releasing the latch means of the second vent.
