SCR-5, delete the following text: 16.6.4 Fire Protection System Design Scheme “E.”

16.6.4.1

Sprinklers and horizontal barriers shall be installed in accordance with Figure 16.6.4.1(a) or Figure 16.6.4.1(b), whichever is applicable. Horizontal barriers shall be of plywood having a minimum thickness of 3⁄8 in. (10 mm) or of sheet metal of minimum 22 gauge thickness. All liquid storage shall be located beneath a barrier.

16.6.4.2

Vertical baffles shall not be installed between in-rack sprinklers.

16.6.4.3

In-rack sprinklers shall meet the following requirements:

Page 12 of 16

(1) In-rack sprinklers shall be intermediate temperature–rated, pendent sprinklers with a nominal K-factor of 25.2 and shall be listed as extended coverage control mode density/area storage sprinklers.

(2) In-rack sprinklers shall be positioned in a transverse flue below each barrier level.

(3) In-rack sprinklers shall not be positioned within 3.5 ft (1 m) of a rack upright.

(4) The minimum in-rack sprinkler discharge pressure shall not be less than a gauge pressure of 30 psi (207 kPa).

(5) Where one level of in-rack sprinklers is installed, the design shall include the 3 most hydraulically remote sprinklers on a single line.

(6) Where two levels of in-rack sprinklers are installed, the design shall include the 3 most hydraulically remote sprinklers on a single line, and the 2 most hydraulically remote sprinklers on the next adjacent level.

(7) Where three or more levels of in-rack sprinklers are installed, the design shall include the 3 most hydraulically remote sprinklers on a single line, and the 2 most hydraulically remote sprinklers on the next two adjacent levels.

(8) Foam-water sprinkler protection shall be permitted to be substituted for water sprinkler protection, provided the same design criteria is used, and that the sprinkler is listed for use with foam.

16.6.4.4

If there are adjacent bays of in-rack arrays that are not dedicated to storage of liquids, the barrier and in-rack sprinkler protection shall be extended at least 6 ft (1.8 m) beyond the area devoted to liquid storage.

16.6.4.5

Ceiling sprinkler demand shall not be included in the hydraulic calculations for in-rack sprinklers.

16.6.4.6

Water demand at point of supply shall be calculated separately for in-rack and ceiling sprinklers and shall be based on the greater demand.

16.6.4.7

Ceiling sprinklers shall meet the following requirements:

(1) Ceiling sprinkler protection shall be designed to protect the surrounding occupancy.

(2) Any sprinkler type shall be acceptable.

(3) If standard spray sprinklers are used, they shall be capable of providing not less than 0.30 gpm/ft2 over 3000 ft2 (8 mm/min over 270 m2) when supplied with water. Design area can be reduced to 2000 ft2 when using a preprimed foam-water system installed in accordance with NFPA 16 and maintained in accordance with NFPA 25.

(4) If the liquid storage does not extend to the full height of the rack, protection for commodities stored above the top horizontal barrier shall meet the requirements of NFPA 13 for the commodities stored, based on the full height of the rack.

16.6.4.8

A 500 gpm (1900 L/min) hose stream allowance shall be provided.
