Why not cut a 100mm (4") slot across the centre of each 2.3m(7'-6") shelf thus producing a transverse flue and reducing the shelf size to that of a pallet and it becomes open shelves. If product could encroach on flue space fit edge barriers or mesh to ensure flue is kept clear.

Sent: Saturday, 9 June 2012 8:50 AM To: [email protected] Subject: Shelf storage for pharmaceuticals Gentlemen: We are dealing with a warehouse for pharmaceutical commodities (class IV), where we have racks and also 5 rows of solid shelf structure 20 ft high with solid shelves spaced vertically 14 inches. Shelf dimensions are 7,5 ft x 3 ft. ( 23 sq ft), arranged so that the lateral flue space is of 5 inches. Roof height is 40 ft. The question regards protection criteria for the solid shelf structures. Per NFPA 13 definition, our shelves do not comply with the maximum depth of 30 inches. Our shelves have 36 inches. Also there are not provisions for shelf storage with a height above 15 ft. Commentary to 14.2.1 on the handbook ( 2010 Edition, page 562) says that shelf storage exceeding 15 ft. can be protected according criteria for rack storage in chapter 16. The issue is that it does not seems possible or effective to protect this solid shelve structure with in-rack sprinklers. It appears that there is no criteria to protect this with only ceiling sprinklers. CMSA and ESFR does not apply to shelf storage. Any idea on how to solve this? J.P.
