A common line for fire main and deck foam line can only
be accepted provided it can be demonstrated that the hose nozzles
can be effectively controlled by one person when supplied from the
common line at a pressure needed for operation of the monitors. Additional
foam concentrate should be provided for operation of 2 nozzles for
the same period of time required for the foam system. The simultaneous
use of the minimum required jets of water should be possible on deck
over the full length of the ship, in the accommodation, service spaces,
control stations and machinery spaces.
