They also facilitate the generation of STEAM that enables a more rapid extinguishment of the fire in the confined spaces of the cockloft.

T/F
The original one piece HRN has not been removed from companies equipped with the combination nozzle. These companies carry both so the non-train members can use the one piece HRN. Engine companies not trained in the use of the combination nozzle system should continue to use the conventional high-rise nozzle or cockloft nozzle as required . 3.7.11 page 18.
