Further testing has developed protection schemes that could allow the liquids in Table to be stored in unlimited quantities. Response Message: Public Comment No. 44-NFPA [Section No. 12.8] Public Comment No. 45-NFPA [Sections A , A ] Page 13 of 37

14 A The provision of automatic sprinklers designed to protect Class IV commodities to a height of 20 ft (6 m) for the liquid storage quantities and arrangements allowed in a general-purpose warehouse should not be construed as providing adequate protection. Fire tests utilizing such design criteria on the allowed storage arrangements have never been conducted, and other test results imply that control of a liquid pool fire might not be obtained. Examples of fire protection can be found in Chapter 16. A In addition to the control of fires provided by a strong protection scheme and the use of listed liquid-container combinations (ignition of packaging scenario), the limiting of container size further reduces the potential for the development of a large accidental spill that could be ignited after its release, resulting in operation of a large number of ceiling sprinklers and wide area ignition of other lower hazard commodities, such as expanded or unexpanded plastics (spill and delayed ignition scenario). This eliminates the need for protection features that would ordinarily be associated with storage of flammable and combustible liquids. A Exception No. 2 is based on work done by FM Global, which showed that flammable liquids in plastic containers could cause uncontrollable fires under certain conditions of storage in generalpurpose warehouses. A research project on flammable liquids container storage carried out by Underwriters Laboratories Inc., under the auspices of the National Fire Protection Research Foundation, has suggested a test protocol that can judge the capability of packaging systems to withstand a small ignition source or to minimize the rate at which the lading is released from the containers, so that the fire can be controlled by automatic sprinklers.

31 1 of 44 9/6/2016 1:40 PM Vertical baffles shall not be installed between in-rack sprinklers In-rack sprinklers shall meet the following requirements: (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.

32 2 of 44 9/6/2016 1:40 PM 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 Ceiling sprinkler demand shall not be included in the hydraulic calculations for in-rack sprinklers Water demand at point of supply shall be calculated separately for in-rack and ceiling sprinklers and shall be based on the greater demand 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/ft 2 over 3000 ft 2 (8 mm/min over 270 m 2 ) when supplied with water. Design area can be reduced to 2000 ft 2 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 A 500 gpm (1900 L/min) hose stream allowance shall be provided.

36 4 of 44 9/6/2016 1:40 PM Second Revision No. 209-NFPA [ Section No ] In-rack sprinklers shall meet the following requirements: (1) In-rack sprinklers shall be ordinary temperature rated, quick-response sprinklers. Sprinklers shall have a nominal K-factor equal to or greater than 8.0. An intermediatetemperature sprinkler shall be used where ambient conditions require. (2) In-rack sprinklers shall be installed below each barrier level. (3) In-rack sprinklers shall provide a minimum discharge flow of 30 gpm (110 L/min) out of each of the hydraulically most remote six sprinklers (six on one line or three on two lines) if one barrier level is provided, or out of each of the hydraulically most remote eight sprinklers (eight on one line or four on two lines on the same level ) if two or more barrier levels are provided. The minimum in-rack sprinkler discharge pressure shall not be less than a gauge pressure of 10 psi (0.69 bar).
