The remote area for a wet hydraulically-calculated sprinkler system contains two different hazard classifications - Light and Ordinary Hazard Group II.
When using the density/area method of NFPA 13, is each sprinkler calculated only to the hazard within the room it protects? If the OH2 spaces are confined to small storage rooms (with walls and doors), does the OH2 density have to extend beyond the OH2 room at all?
