Hiii
I visited a warehouse (8.6 m height) which is protected by upright sprinklers (K-5.6) . Now the client have added a steel mezzanine structure with racks above and below. Now local Fire authority have asked to *provide sprinklers(in rack type) at the ceiling level of the mezzanine for the below racks.* ** Racks below will be stored with electronic good items in cartons (mainly items for electronic panels). Max storage height will be 4 m. Their are 5 multiple row racks (2.4m wide and 9.3 m length) and 2 single row racks of 1.2 m wide and 9.3 m length). aisle width of 1.2 m between racks. >From NFPA ,I could see only one layer rack sprinklers enough for each rack and since only 9.3 m length I need only 3 in rack sprinklers per rack. when the sprinklers provided at ceiling Is this the correct way forward?? Can we provide In rack sprinklers at ceiling in these cases? I am not finding it easy to locate the answer. Any help welcome Thaanx in advance Sam _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
