11.5.1 General
Sprinklers protecting double row racks shall be positioned in the longitudinal flue spaces, preferably in
the intersection with the transverse flue (see Figures 9 and 10).
Whenever any rack or structural steelwork is likely to interfere significantly with the water discharge
from the sprinklers, additional sprinklers shall be provided and taken into account in the flow calculation.
It shall be ensured that water from sprinklers operating at intermediate levels can penetrate the goods
stored. The distance between goods stored in racking and placed back to back shall be at least
0,15m, and if necessary pallet stops should be fitted. There shall be a clearance of at least
0,15m from the sprinkler deflectors to the top of the storage.
