NFPA-13 2002 Table 8.12.2.2.1 Protection Areas and Maximum Spacing of ESFR 
Sprinklers.   



iven: a large structure that is 32 feet high at one end and 29'-4½ high at the 
low point. 

he storage area requiring ESFR heads is located in the middle areas of the 
building. The high point 
 is 31' at the northern edge of the storage area.The roof slopes down to 29'4.  
About 50' of the room has a structure that is 30 feet or less. Could this "low" 
area utilize 
the 12 foot maximum spacing allowed by NFPA?  (100 sq.ft.- 12' max..spacing) Or 
must the entire area 
be spaced 10' x 10' maximum?
