Is it a concealed space? If so, is it combustible or non-combustible? NFPA 13 will consider a building fully sprinklered while allowing sprinklers not be installed in all areas. Does your space meet the criteria to be exempted from sprinklers? Travis Mack,

That is for CMSA only. Using standard spray, you want to look at 8.6.5.2.1.8. That is the reference for smaller than 3” not needing to meet the 3x rule. For 3” and larger, you must comply with 3x rule for standard spray. Travis Mack, CFPS, CWBSP, RME-G, SET

It is my understanding you can use the ceiling with the pendent sprinklers as the floor level when measuring the QR reduction. Travis Mack, CFPS, CWBSP, RME-G, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107

Brian: You say the insurance guy is saying Grp A on racks. 25’ storage 30’ ceiling. Chapter 15 is solid piled / palletized. 0.45/2500 is 12’ storage up to 15’ ceiling. I think you are a bit off there based on your description. Chap 17 is rack storage of plastics. Location has meaning.
