Obstructions to ESFR and CMSA Sprinklers

Victoria B Valentine, PE

Early suppression fast response sprinklers (ESFR) and control mode specific application (CMSA) sprinklers are commonly used in protecting storage scenarios.  These sprinklers undergo different product testing in order to achieve their listing.  With the large volume of water that comes from each of these sprinklers they are extremely sensitive to obstructions.  Fixtures, structural members, and more, may or may not be considered obstructions to sprinkler discharge.  This seminar will explore the rules for positioning ESFR and CMSA sprinklers when obstructions are present.
