Shadow Areas

The NFPA sprinkler standards do not require water to physically spray on every square foot of floor area in a building.  Obstructions such as columns, wing walls and partitions are allowed to exist which create small areas within the sprinkler’s coverage area where water may not directly fall.  This presentation will discuss the limitations and allowances of NFPA 13, NFPA 13R and NFPA 13D with respect to this feature that sometimes occurs in sprinkler system layout.


Approved for Contractor I, II, IV and Waterbased Inspectors.
