In rack sprinklers water demand
In rack sprinklers water demand
(OP)
Greetings colleagues,
I have a room that will store chemicals in plastic bins in racks of two rows. The room has ceiling sprinkler but we will be installing in rack sprinklers in both rows. For the hydraulic calculation I'm considering 7 active sprinklers per level (14 total) plus a hose demand of 500 gpm. Do I need to balance this demand with the ceiling sprinklers and supply the water demand for both? I had the notion that if the in rack sprinklers work properly it would prevent the ceiling sprinklers from activating simultaneously unless it was a really intense fire.

12.1.3.4.5 Where the clearance to ceiling exceeds 10 ft (3.0 m) for Section 16.3 or Section 17.2, protection shall be based upon the storage height that would result in a clearance to ceiling of 10 ft (3.0 m) or providing one level of supplemental, quick-response in-rack sprinklers located directly below the top tier of storage and at every flue space intersection.
