This fire protection plan, along with the enclosed HPS—I and HPS-2 storage plan, are being provided to you to outline how Bed, Bath & Beyond will achieve compliance with the Uniform Building and Fire Codes (UBC and UFC respectively). This report and the aforementioned drawings are provided for information and support for the application for the high-piled storage permit. Lastly, we anticipate that these documents will assist your department during the plan review process by providing the basis on which the design criteria was determined. This plan is based specifically on the 2001 California Building & Fire Code, as well as the 1999 edition of NFPA 13. GENERAL Bed, Bath & Beyond will occupy approximately 27,654 ft' of gross floor area. Of that area, just over one-third will be occupied by storage and display that is high-piled storage, while the remaining area will be occupied by storage and display that is low-piled storage, or some other accessory use such as offices or restrooms. Distances to exits do not exceed 200 feet at any point in the store. In addition, the stores are completely sprinklered and comply fully with all applicable standards governing high-pile storage retail warehouses. STORAGE & DISPLAY CONFIGURATIONS There will be several different storage and display configurations found in this store, including solid piled/palletized and shelf storage/display. Sheet HPS-1 shows the delineation between low-piled and high-piled storage/display areas of the main sales floor, and it also provides an area summary for the different types of storage/display that will be found throughout the store. As this plan indicates, the total high piled storage area within the building is 10,954 ft2.. The following is a brief narrative of the information presented on the referenced drawings, as well as a review of the UFC requirements for each type of storage. Solid Piled/Palletized Storage & Display Solid piled/palletized storage and display will be found at various locations on the main sales floor and also in the receiving dock area of the store. Products that will be stored or displayed in this manner include Class I-IV commodities and limited quantities of Group A plastics. It can be seen from Sheet HPS - I that in no case will solid piled/palletized storage or display occupy an individual floor area of more that 32 ft2, which is roughly equal to two (2) pallet loads of product. Maximum storage heights for this type of storage/display configuration will be 6 ft. for all products. Because storage heights will be at or below 6 ft. for all commodities involved, products stored or displayed in this manner will be considered low-piled storage, and will not be included in the total floor area used to determine the requirements of UFC Table 81-A. Shelf .Storage & Display Shelf storage and display will be found throughout the main sales floor and in the receiving backstock storage area. Products that will be stored or displayed in this manner again include Class l-IV commodities and limited quantities of Group A plastics. Typical storage heights on the main sales floor for this storage configuration will be either 6 ft. or 15 San Diego. CA • Los Angeles. CA • Detroit, Ml • Atlanta, GA • Dallas, TX • Parsippany. NJ Minneapolis, MN • Seattle, WA • St. Louis, MO Bed, Bath & Beyond - Carlsbad. CA Fire Protection Plan Page 2 of 5 ft. maximum, depending on the product and location. All shelf storage in the receiving backstock storage area will be to a maximum of 15 ft. Shelf storage/display on the main sales floor that is in excess of 12 ft. for Class l-IV commodities, and in excess of 6 ft. for Group A plastics, as well as all storage in the receiving backstock storage area will be considered high-piled combustible storage, and therefore will be included in the total floor area used to determine the requirements of UFC Table 81-A. Shelf storage/display on the main sales floor that is less than 6 ft. high will be considered low-piled storage, and therefore will not be included. Rack Storage The only racks within the facility are found within Receiving/Stock Area. The remainder of the fixtures are shelf storage. COMMODITY CLASSIFICATION INFORMATION As was stated previously, the commodity classifications for products that will be found in this store range from Class I noncombustible products in cardboard containers to High Hazard Group A plastics. UFC Section 8 101.4.1 provides examples for the various types of commodities and their proper classification. In addition to these examples, there are three code sections that are critical to determining commodity classification, and ultimately to determining the overall classification of the building. First, UFC Section 269 provides the Code's definition of High-Piled Combustible Storage, which includes "...storage of combustible materials in closely packed piles or combustible materials onpallets, in racks or on shelves where the top of storage is greater than 12 feet in height." This definition also gives the Fire Chief the latitude to include "...certain high-hazard commodities, such as... Group A plastics... and similar commodities, where the top of storage is greater than 6feet in height." This definition is important because approximately 60% of the storage in this building will be at heights less than 6 feet, with most of the high-hazard commodities being stored at heights less than 6 feet. Second, UFC Section 8101.4.3 and Figure 8101.4-A provide criteria which allow a commodity containing limited amounts of Group A plastics to be classified as a Class IV or Class III commodity. Specifically, if a commodity contains only 10-15% by weight of unexpanded Group A plastics, it can be considered a Class IV commodity, and if less than 10% by weight it can be considered a Class III commodity. This type of analysis is important for products such as pillows, comforters, kitchen appliances and other similar products that will be found in a Bed, Bath & Beyond store. Finally, UFC Section 8 101.5.2 allows the designation of a high-piled combustible storage area to be based on a lesser hazard class provided the higher hazard product is limited in quantity and the sprinkler system can be demonstrated to provide the level of protection (i.e. the appropriate application density) necessary for the higher hazard commodity. This requires an engineering analysis of both the commodity classifications for all products and the sprinkler system design requirements for all products. Specifically, if the following criteria can be met, the lower hazard classification will be allowed: Storage of the higher hazard commodity must be limited to a contiguous floor area of no more than 120 sq. ft., Where multiple areas of higher hazard commodity are present, they must be separated from each other by a minimum of 25 feet, and The sprinkler system must be able to deliver the application density for the higher hazard commodity over a minimum 900 sq. ft. design area. The quantity of Group A plastics that will be found in this store is limited, with the majority of these products being stored or displayed in solid piles or on low-piled shelf storage units to a maximum height of 6 feet. Where these products are stored at heights above 6 feet, they are arranged so that the storage meets the requirements of UFC Section 8101.5.2. Bed, Bath & Beyond - Carlsbad, CA Fire Protection Plan Page 3 of 5 In particular, the Group A plastic products are consolidated into clusters occupying floor areas of 120 sq. ft. or less, with these clusters being separated from each other by a distance of at least 25 feet. Additionally, back stock of any given product will be found on the shelving immediately above the display for that product. Finally, because the sprinkler system is designed for the worst case of Group A plastics, the density is already provided. Therefore, because the storage configuration and the sprinkler system will both be able to meet all of the criteria set forth in UFC Section 8101.5.2, the appropriate commodity classification for this building will be Class IV. SPRINKLER DESIGN CRITERIA The automatic wet-pipe sprinkler system required by UFC Table 81-A will be design and installed in accordance with the 1999 edition of NFPA 13. The design criteria for the building will be based on Group A plastics. The storage and display configuration used in this store has one more somewhat unique aspect, that being the fact that it is shelf storage to 15 ft. The requirements for protection of solid piled/palletized and shelf storage/display of Group A plastics are presented in NFPA 13, Section 7-3.3, while the requirements for protection of rack storage of these products are presented in NFPA 13, Section 7-4.4. As with the Class 1-IV protection requirements, there are a number of factors that must be considered before the appropriate level of protection can be determined, including whether the plastic is expanded or nonexpanded, cartoned or exposed, and if the pile is stable or unstable. For this store, all storage configurations will include expanded: and nonexpanded, cartoned and exposed, stable piles of commodity. The following summaries present the conditions that will be found in this store, along with the required design density criteria. Solid-piled and Shelf Storage Up To 6 feet High (Main Sales Floor) Maximum Storage Height: 6'0" under a 17'-4" max. high ceiling Minimum Aisle Width: 410" Packaging Methods: Cartoned and exposed, nonencapsulated, stable piles Temperature Rating: 286 OF Base Design Criteria: 0.271 gpm/ft2 - Determined from NFPA 13, Column C of Table 7-3.3.2.2, interpolating between 5 ft. and 12 ft. storage heights as allowed by Section 7- 3.3.2.2.2. Shelf Storage In Excess of 15 feet High Maximum Storage Height: 15'-0" under a 17'-4" max. high ceiling Minimum Aisle Width: 410" Packaging Methods: Cartoned and exposed, nonencapsulated, stable piles Temperature Rating: 286 OF Base Design Criteria: 0.40 gpm/ft2 - Determined from NFPA 13, Column C of Table 7-3.3.2.2, Rack Storage or Shelf Storage In Excess ofl5ft. High (Receiving/Stock Areq) Maximum Storage Height: 15'-0" under a 17'-4" max. high ceiling Minimum Aisle Width: 410" Packaging Methods: Cartoned and exposed, nonencapsulated, stable piles Temperature Rating: 286 OF Base Design Criteria: 0.45 gpm/ft2 - Determined from NFPA 13, Figure 7-4.4.2.3 In this case the 15 ft. high rack storage configuration results in the most restrictive design criteria for the main sales floor. Bed. Bath & Beyond - Carlsbad, CA Fire Protection Plan Page 4 of 5 GENERAL FIRE PROTECTION & LIFE SAFETY REQUIREMENTS Requirements for fire protection and life safety features are presented in UFC Section 8102 and Table 81-A. Application of these requirements is driven primarily by the hazard classification of the commodities being stored or displayed, and the total floor occupied by the storage/displays. The hazard classification of the storage area is in turn dependent on the commodity classification of the products being stored or displayed and the storage heights. The impact of the Code's definition of high-piled combustible storage has been discussed previously. Sheet HPS- I shows the limits of all areas having storage and/or displays more than 12 feet in height for Class I-IV commodities and more than 6 feet in height for high hazard commodities. The limits for these areas have been laid out to include all shelf storage and any adjacent aisles, up to a maximum aisle width of 30 inches, which is the minimum required aisle width for shelf storage, as well as the stockroom. From the HPS-I plan it can be seen that there is a total of 10,954 ft' of public and non-public accessible high-piled storage on the main sales floor, backstock storage area, and the receiving/backstock storage area. Fire Department Access Fire Department access roads are provided on both the front and rear of the building (even though they are not required by UFC Table 81-A). Because there is no high-piled storage area in excess of 12,000 ft' in this building, additional doors above those required for normal exiting are not required by UFC Table 81-A. Smoke and Heat Removal Because there is no high-piled storage area in excess of 12,000 ft' in this building, smoke and heat vents are not required by UFC Table 81-A. Hose Stations and Hose Connections Because there is no high-piled storage area in excess of 12,000 ft' in this building, hose stations and hose connections are not required by UFC Table 81-A. Curtain Boards Curtain boards are not required by UFC Table 81-A. Because this is a Group M occupancy building under 50,000 sq.ft. in undivided area, curtain boards are riot required by UBC section 906.1. Aisles Aisle widths will vary by location in the store. In all cases, the minimum aisle width will be maintained at 4 ft. It can be seen from Sheet HPS-1 that some of the aisles are much larger than this (i.e. 12 to 16 feet), but these larger areas will typically be used for solid-piled floor displays. When this is the case, the minimum clear width between the floor displays and adjacent shelf storage structures will be maintained at 3 ft. In the backstock storage areas, the minimum aisle width will be maintained at 4 ft. Flue Spaces Flue space requirements do not apply to shelf storage and solid-piled/palletized storage configurations (UFC Sections 8103 & 8104). All rack storage structures that will be found in this store will be single row racks, and therefore are not required to be provided with longitudinal flue spaces. Minimum 3 inch transverse flue spaces will be provided in the rack storage structures. Bed, Bath & Beyond - Carlsbad, CA Fire Protection Plan Page 5 of 5 Housekeeping & Maintenance Practices The following general house keeping and maintenance practices will be instituted: Proper clearances will be maintained between combustible stock and all ignition sources. Minimum vertical clearance of 18 in. will be maintained between top of storage and sprinkler deflector. Smoking will be prohibited within the store, and NO SMOKING signs will be conspicuously displayed. Exit doors will be maintained clear and unobstructed, and will be opened weekly to ensure their operation. Exit signs will be kept illuminated while the building is occupied. Emergency lighting in the building will be checked monthly. During restocking operations, a minimum unobstructed aisle width of 2 ft. will be maintained. Fire extinguishers will be mounted three feet to five feet from the floor in a conspicuous area and identified with a sign. Fire extinguishers will be placed so that an occupant would not have to travel more than 75 feet to reach one. We feel this fire protection plan is complete, and will provide adequate fire and life safety for the occupants of the building.
