When in use the discharge end of the hose will be fitted with a nozzle so that the operator may control the manner in which water is projected at a fire. Standard nozzle sizes are 12 mm, 16 mm and 19 mm.
Spray nozzles must be capable of producing a plain jet without spread and have a throw of at least 12 m. The spray must produce a reasonably fine spray which can form a curtain, from behind which it is possible to approach a fire. The spray pattern would have a diameter of, say, 5 m at a distance of 2 m from the nozzle.
A standard type of nozzle which by a twist-grip operation is able to shut off the hose discharge or deliver it as a jet or spray according to the operator’s desire. Some diffuser nozzles also have a water curtain capability.
When large volumes of water are used for fire fighting consideration must be given to the stability of the vessel.
