Attic Fire Nozzle

Haven South LLC is introducing a new technology focused on attacking attic fires in both residential and commercial construction. This technology is called attic fire attack suppression technology (AFAST). AFAST is a nozzle that will flow approximately 200 gallons per minute (gpm) into a fully charged attic fire and within one minute should quell the fire. The only moving part on this nozzle is the shut-off valve. Without obstructions, the flow pattern is about 35 feet, covering a 360-degree area with a deluge of water. The nozzle itself is attached to a five-foot piece of pipe for elevation into the attic itself. Once the nozzle has cleared the mark on the pipe it can be opened for operation. The ideal attack is vertical and as far upward into the attic as possible then bring it back down before shutting it off. It is recommended that the nozzle operation be limited to one minute before evaluation from the IC outside the building or by visual inspection from inside.

Ventilation of the roof or gable ends is a must for the operation of this nozzle. Without ventilation the steam pressure build up on the attic space could become critical and could come back down on the firefighters below. Ventilation will allow the IC to observe the smoke condition changes that will take place while the nozzle is in operation.

The AFAST nozzle comes complete and ready to use. The shut-off valve has a pistol grip style for ease in moving the nozzle into the attic area. It is recommended that this nozzle be preconnected in the hosebed for quick deployment. Being placed at the front door not charged and ready for movement into the upper floors is the best tactic. Once in place in the room below the attic, a hole can be placed in the ceiling with a tool of choice that will allow the nozzle to be inserted into the attic area. This tool is not a piercing nozzle. In older homes that are of balloon construction obstructions might include floor boards, and or chimneys. If that is the case then the scuttle hole must be found. In newer homes it is usually the truss boards that will be the obstructions but moving the nozzle up and down will clear most of those at one point or another.
