Extensive trials were carried out at West Midlands FRS training facility at Oldbury where a first floor room was taken to 600 degrees in a controlled fire situation. Using the Floor Below Nozzle, from the room below, the temperature was reduced to 90 degrees in just 20 seconds without a single fire fighter entering the test room.The Floor Below Nozzle is specifically designed to be long enough to protrude out of a lower window where the long, angled barrel is raked upwards, firing a solid jet of water through the upper window, hitting the ceiling and rapidly gas cooling prior to fire crew entry. This is a major step forward in High Rise fire fighter safety and significantly reduces the risks associated with rising room temperatures.Supplied as standard with 2½” Instantaneous Male or BSP threaded inlet fitting the Floor Below fire nozzle is fully sectional for ease of transportation and independently controlled via a lever-operated ball valve.
