These Guidelines have been developed in recognition of reasonable
and realistic performance-based requirements for fixed water-based
fire-fighting systems for ro-ro spaces and special category spaces.
These Guidelines and the fire tests are intended for closed
ro-ro spaces and special category spaces defined by SOLAS regulations II-2/3.12 and II-2/3.46, respectively.
Deluge systems can be applied on open ro-ro spaces when the actual
wind condition is taken into consideration. Systems using automatic
sprinklers are only permitted for closed ro-ro and special category
spaces or other spaces where wind conditions are not likely to affect
system performance.
