Question 1.

NFPA 13 2010 Figure 17.2.1.2.1(d)

Top left corner plan view shows 8 ft max spacing going left to right. I am being told that the max spacing is 8 feet in the up to down the plan view also. I am a little confused on the 8" max spacing when using only 1 row of rack sprinklers. Where does it state so in NFPA?

 

Question 2.

Referring to the same figure 17.2.1.2.1(d) under notes. Note 1 states single level of in-rack sprinklers operating......

I am being told that the meaning is for me to have to calculate the entire level of in rack sprinklers. Where 17.2.4.3 Is telling me that I only have to calculate the 8 most demanding for one level of in racks. Which is correct.
