 Concealed Space Protection 



Presenters: Karl Wiegand, P.E.



NFPA 13 requires that all combustible spaces greater than 6 inches in height be protected by sprinklers.  However, standard spray sprinklers are not capable of developing adequate spray patterns to provide acceptable protection for spaces that are between 6 and 36 inches in height.  For these spaces specially listed sprinklers that provide a more horizontal spray pattern that is capable of developing quickly are necessary.  NFPA 13 acknowledges this and requires the use of sprinklers that has been specifically listed for combustible concealed spaces to be used in all spaces between 6 and 36 inches in height.  The standard does not, however, provide any installation requirements for these sprinklers.   In order to pass their rigorous testing requirements, these specially listed sprinklers that are used in combustible concealed spaces need to be installed in different configurations that typical spray sprinklers.  The intent of this presentation is to provide guidance at to what types of spaces these sprinklers can protect and the different installation requirements for protecting each of these types of spaces to stay within these sprinklers’ listings.
