The conversation in the office kept going back to hvac ductwork and how you would place an ESFR sprinkler underneath when it became an obstruction... Normally there will be commodity stored under the duct, but in this situation, no stock will be in the catwalks, just the racks... so the additional ESFR sprinklers will spray the catwalks and not necessarily the commodity... is this over kill??

For any other obstruction you would use the same ESFR's below the obstruction as you used at the ceiling/roof. Craig L.

Do you continue installing ESFR sprinklers under each level or can you install control mode sprinkler under the catwalks while the ESFR's at the ceiling protect the commodity?? I did look up the archives and a few people have asked similar questions over the years, but I don't see an answer... NFPA 13, 2007 ed. Thank you in advance!
