Patent attributes
The present invention provides a firefighting system using a boom truck for delivering fire suppressant fluid to remote areas in burning structures. The system includes a fluid delivery conduit having a distal end fitted with a nozzle that discharges fluid in a 360 degree arc perpendicular to the direction of the conduit. The nozzle is constructed using a first disk with a central opening, and a second disk attached in spaced relationship having a curved conical projection that extends back through the central opening in the first disk. A third disk with a conical forwardly extending projection is attached to the second disk. When the conical projection is forced through a window on a building wall section, fluid is discharged to otherwise inaccessible areas in the building and harmful gases are simultaneously vented from the building.
