John It should be recognized that the above is my opinion as a member of the NFPA 13 Technical Committee on Sprinkler Discharge Criteria, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the AFSA nor the NFPA, nor any of their technical committees.

Ed Kramer Lawrence, KS -----Original Message----- From: sprinklerforum-boun...@lists.firesprinkler.org [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Todd - Work Sent: Wednesday, November 20, 2013 8:45 AM To: sprinklerforum@lists.firesprinkler.org Subject: Misc storage and QR sprinkler deduction I am working on a school project where there is a basement that will be used for storage (3300 sqft, 13 ft ceiling). I am basing my design on 10 ft high storage of miscellaneous stuff, which I am calling Class IV. This would be a 0.20/1500 sprinkler density, which is the same as the requirement for OH2. Since I have a marginal water supply and am at the far end of the system, minimizing the design is critical. My question is this; can I use the RA deduction for QR heads in OH2 with the curves for low piled storage? Or does the fact that this is storage negate that reduction? Must be my day for question....
