Look at heights measured from the top of the pallet storage rack. From: Sprinklerforum [mailto:[email protected]] On Behalf Of James Crawford Sent: 2018/11/13 3:19 PM To: [email protected] Subject: Pallet storage above overhead doors
We are working on a project where the tenant wants to store pallets above the overhead loading doors to a height of 6'-0" in the loading dock area.. The project will be using Factory Mutual data sheets, so I went to DS8-24 Idle Pallet Storage and because they are on racks it send me to DS8-9 and 8-9 tells me to use rack storage for Un-cartoned, un-expanded Group "A" plastics Table 10. Based on the height of the building (40'-0") I would need ESFR K25 operating at 60psi to protect 6'-0" of wooden pallets, this seems a little excessive. So if we add a level of in-racks sprinkler heads and use Table 13 we would have 5' to 10' storage above the sprinkler and 10' to 20' clearance above the top of the pallets. So this tells me to use the 15' storage from Table 10 or ESFR K25 @ 25psi plus 1 level of in-racks. Still seems a little excessive. Am I reading this right?
