We have a building with a 70ft deck that is classified as OH2. We have been asked by the insurance company to use the 2025 version instead of our adopted 2019 version. From the table 19.2.3.2.5 we are going to use 11.2k standard spray sprinklers at a density of 0.45/1950. My questions are.... 1 - Do I go with 100sq ft max area per head because the density is 0.45 or can I use 130sq ft because the area is still considered OH2? I would think 130sq ft but just want to verify. 2 - Do I go with 250 or 500 hose? I would think 250gpm.
