SECTION 2304 DESIGNATION OF HIGH-PILED STORAGE AREAS 2304.1 General. High-piled storage areas, and portions of high-piled storage areas intended for storage of a different commodity class than adjacent areas, shall be designed and specifically designated to contain Class I, Class II, Class ifi, Class N or high-hazard commodities. The designation of a high-piled combustible storage area, or portion thereof intended for storage of a different commodity class, shall be based on the highest hazard commodity class stored except as provided in Section 2304.2. 2304.2 Designation based on engineering analysis. The des- ignation of a high-piled combustible storage area, or portion thereof, is allowed to be based on a lower, hazard class than that of the highest class of commodity stored when a limited quan- tity of the higher hazard commodity has been demonstrated by engineering analysis to be adequately protected by the auto- matic sprinkler system provided. The engineering analysis shall consider the ability of the sprinkler system to deliver the higher density required by the higher hazard commodity. The higher density shall be based on the actual storage height of the pile or rack and the minimum allowable design area for sprin- kler operation as set forth in the density/area figures provided in NFPA 13. The contiguous area occupied by the higher haz- ard commodity shall not exceed 120 square feet (111 m2) and additional areas of higher hazard commodity shall be separated from other such areas by 25 feet (7620 mm) or more. The sprin- kler system shall be capable of delivering the higher density 282 over a minimum area of 900 square feet (84 m2) for wet pipe systems and 1,200 square feet (11 m2) for dry pipe systems. The shape of the design area shall be in accordance with Section 903. SECTION 2305 HOUSEKEEPING AND MAINTENANCE 2305.1 Rack structures. The structural integrity of racks shall be maintained. 2305.2 Ignition sources. Clearance from ignition sources shall be provided in accordance with Section 305. 23053 Smoking. Smoking shall be prohibited. Approved "No Smoking" signs shall be conspicuously posted in accordance with Section 310. 2305.4 Aisle maintenance. When restocking is not being con- ducted, aisles shall be kept clear of storage, waste material and debris. Fire department access doors, aisles and exit doors shall not be obstructed. During restocking operations using manual stocking methods, a minimum unobstructed aisle width of 24 inches (610 mm) shall be maintained in 48-inch (1219 mm) or smaller aisles, and a minimum unobstructed aisle width of one-half of the required aisle width shall be maintained in aisles greater than 48 inches (1219 mm). During mechanical stocking operations, a minimum unobstructed aisle width of 44 inches (1118 mm) shall be maintained in accordance with Section 2306.9. 23053 Pile dimension and height limitations. Pile dimen- sions and height limitations shall comply with Section 2307.3. 2305.6 Arrays. Arrays shall comply with Section 2307.4. 2305.7 Flue spaces. Flue spaces shall comply with Section 2308.3.

Figure 1) are automatic sprin- klers of the fusible solder type. They are "standard response - spray sprin- klers" that produce a hemispherical water distribution pattern below the deflector. The 11.2 K-factor, ELO-231 Sprinklers were subjected to full scale, high-piled storage, fire tests to qualify their use in lieu of 5.6 or 8.0 K-factor standard spray sprinklers for the protection of high-piled storage. Higher flow rates can be achieved at much lower pressures with the 11.2 K-factor, ELO-231 Sprinklers - mak- ing their use highly advantageous in high density applications, such as the protection of high-piled storage. Wax or lead coatings can be used to extend the life of the copper alloy com- ponents used in Series ELO-231 sprin- klers beyond that which would other- wise be obtained when exposed to corrosive atmospheres. Although wax and lead coated sprinklers have passed the standard corrosion tests of the applicable approval agencies, the testing is not representative of all pos- IMPORTANT Always refer to Technical Data Sheet TFP 700 for the "INSTALLER WARNING" that provides cautions with respect to handling and instal- lation of sprinkler systems and com- ponents. Improper handling and in- stallation can permanently damage a sprinkler system or its compo- nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely. Page 1 of 6 sible corrosive atmospheres. Conse- quently, it is recommended that the end user be consulted with respect to the suitability of these corrosion resis- tant coatings for any given corrosive environment. The effects of ambient temperature, concentration of chemi- cals, and gas/chemical velocity, should be considered, as a minimum, along with the corrosive nature of the chemical to which the sprinklers will be exposed. An upright intermediate level version of the Series ELO-231 Sprinklers for in-rack applications can be obtained by utilizing the Series ELO-231 Up- right Sprinkler with the WSG-2 Guard & Shield, and a pendent intermediate level version of the Series ELO-231 Sprinklers can be obtained by utiliz- ing the Series ELO-231 Pendent Sprinkler with the WS-2 Shield. If there is a possibility of the pendent interme- diate level version being exposed to mechanical damage, a G-2 Guard can be added. WARNINGS The 11.2 K-factor, Series ELO-231 Upright and Pendent Sprinklers de- scribed herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the National Fire Pro- tection Association, in addition to the standards of any other authorities hav- ing jurisdiction. Failure to do so may impair the performance of these de- vices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition. The installing contractor or manufac- turer should be contacted with any questions. Installation of Series EL 0-231 Pen- dent Sprinklers in recessed escutch- eons will void all sprinkler warranties, as well as possibly void the sprinkler's Approvals and/or Listings.
