JUMP TO FULL CODE CHAPTER
In-rack sprinklers shall be installed at the first tier level at or above one-half of the storage height.
The minimum of 6 in. (150 mm) vertical clear space shall be maintained between the sprinkler deflectors and the top of a tier of storage.
(A) Sprinkler discharge shall not be obstructed by horizontal rack members.
In-rack sprinklers shall be located at an intersection of transverse and longitudinal flues.
The maximum horizontal distance between in-rack sprinklers shall be 5 ft (1.5 m).
Where distances between transverse flues exceed the maximum allowable distances, sprinklers shall be installed at the intersection of the transverse and longitudinal flues, and additional sprinklers shall be installed between transverse flues to meet the maximum distance rules.
Where no transverse flues exist, in-rack sprinklers shall not exceed the maximum spacing rules.
The water demand for sprinklers installed in racks shall be based on simultaneous operation of the most hydraulically remote eight sprinklers.
Sprinklers in racks shall discharge at not less than 15 psi (1.0 bar) for all classes of commodities. (See Section C.19.)
