ABSTRACT:
A dual purpose fire fighting and ventilation apparatus comprising a rigid conduit having an inlet end to be connected to a source of water under pressure and having an outlet end. The conduit is mounted in a generally horizontal position in an opening in a building such as a window or doorway, and a fogging nozzle is connected to the outlet end and is located within the building. Manually operable controls serve to adjust the spray pattern of the nozzle as well as moving the nozzle in a vertical path. In use, the conduit is inserted through the opening in the building and locked to the building with the nozzle facing outwardly through the opening. The spray pattern is adjusted and the nozzle is then elevated to create a spray pattern back through the opening and thus provide an aspirating action to draw smoke and air outwardly through the opening to reduce the upward propagation of combustion.
