The Small Room Rule allows for simplified sprinkler layout and calculations in spaces where the fire hazard is considered low and the room size is relatively small. This simplification recognizes that the limited space and occupancy type reduce the risk of a rapidly spreading fire, allowing for a less stringent sprinkler system design.
These modifications offer flexibility in sprinkler placement within small rooms without compromising fire protection effectiveness.
