The present invention relates to a spray head for effective fire fighting. The spray head according to the present invention provides a uniform distribution of a fluid, such as pressurized water, over a relatively large area. To achieve this the spray head comprises a body defining a center axis and further comprising a fixation structure for fixing the spray head to a fluid supply system, a fluid inlet, a plurality of outlet nozzles arranged around the center axis, and a flow path between the inlet and the nozzles, wherein a first set of nozzles are located at a larger radial distance from the center axis than a second set of nozzles, and wherein the second set of nozzles are located at a larger radial distance from the center axis than a third set of nozzles, and wherein the nozzles comprise an essentially identical expansion passage section. The present invention further relates to method for providing a uniform fluid distribution.

The present invention concerns a portable building fire suppression system which allows fire-fighters to position the device within a building early on in the firefighting process. The device may use automated controls to begin fire suppression. Further, a number of electronics including lighting, smoke detection, alarms, camera, motion sensor, and the like may be included on the portion of the device inserted into the building. These electronic systems may provide vital information early in the firefighting process to inform fire fighters about conditions within the building.
