2 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] Special Definitions. The following is a list of special terms used in this chapter: (1) Anchor Building. A building housing any occupancy having low- or ordinary-hazard contents and having direct access to a mall structure, but having all required means of egress independent of the mall concourse. (See ) (2) Food Court. A public seating area located in a mall concourse that serves adjacent food preparation tenant spaces. (See ) (3) Gross Leasable Area. Fifty percent of major tenant areas, and 100 percent of all other floor areas designated for tenant occupancy and exclusive use, including storage areas. The area of tenant occupancy is measured from the centerlines of joint partitions to the outside of the tenant walls. (See ) (4) Mall c C oncourse. A roofed or covered common pedestrian area within a mall structure that serves as access for two or more tenants and does not exceed three levels that are open to each other. (See ) (a)* Open Mall Concourse. A mall concourse that either (1) has 50 percent or more of the total area of the solid mall concourse perimeter walls and solid roof area open to the atmosphere with openings distributed uniformly over the length of the mall concourse, or (2) has an approved open mall concourse engineering analysis. (b) Enclosed Mall Concourse. A mall concourse that does not meet the definition of open mall concourse. (5)* Mall Structures. A single building enclosing a number of tenants and occupancies wherein two or more tenants have a main entrance into one or more mall concourses. For the purpose of this chapter, anchor buildings shall not be considered as a part of the mall structure. (See ) (6) Major Tenant. A tenant space, in a mall structure, with one or more main entrances from the exterior that also serve as exits and are independent of the mall concourse. (See ) Supplemental Information File Name A _4_a_.docx A _5_.docx Description Submittal Date: Mon Aug 01 14:46:47 EDT 2016 Response Message: The proposed changes are the result of task group work that was initiated at the completion of the 2015 revision cycle. The focus of the task group was to update terminology related to shopping malls to better describe the applicability and intent of the Code sections as well as develop language to address both enclosed and open mall concourses. The changes proposed here as public comments represent a continuation of the work proposed during the First Draft stage. The focus of these changes is to clarify the proposed definitions of open and enclosed mall concourses and to address the impact of these new definitions on the current mall provisions. Open mall concourses are becoming a very common design of mall type structures where as much of the pedestrian area is open to the outside. The provisions developed here recognize this now popular design approach and also recognize that the hazards with open mall concourses are different than enclosed mall concourses. Much thought and discussion was contributed by the full committee during the Second Draft meeting. Annex language was carefully developed to assist users in understanding and applying the new open mall concourse concept. The changes proposed in the multiple Second Revisions throughout Section incorporate the concept of open mall concourse as set forth in the definitions shown in this revision. Public Comment No. 125-NFPA [Section No ]

3 A (4)(a) An open mall concourse is permitted to serve as the public way provided that the open mall concourse meets the definition of public way in accordance with this Code. It is intended that the open mall concourse be designed, constructed, and arranged to permit the natural venting of smoke and other products of combustion to the outside air through openings in the walls, roof, or combination thereof of the mall concourse. The solid area of the mall concourse walls and horizontal projection of the solid area of any roof structures, including shade structures, awnings, and canopies, that cover the mall concourse is to be summed to determine the aggregate area of solid construction associated with the mall concourse. A mall concourse can be considered an open mall concourse where at least fifty percent (50%) of the aggregate area of solid construction is open to the atmosphere. Open areas can include entrances to the mall concourse (e.g. such as barred gates which allow air to pass through versus an entrance storefront), clearstory spaces between the mall building (structure which houses tenants) and the roof above, and openings in the roof assembly. In order for the openings to be effective they must also be distributed uniformly over the length of the mall concourse. Caution must be exercised in the design and construction so as to not create areas of possible congestion for smoke and hot gasses to accumulate, such as a pitched (steep slope) roof assembly within the mall concourse. Roof assemblies are permitted to have holes or open areas which represent openings to the outside. The roof assembly is also permitted to consist of a structure or assembly which allows the venting of the mall concourse. Examples of these vented roof structures include a roof trellis or an exposed roof structural frame only with no roofing materials. These types of structures that would permit the omission of automatic sprinkler protection, in accordance with NFPA 13, could be included to serve as open space for the purposes of the calculation of areas open to the outside air. Caution should be taken not to allow vegetation to grow into and around these structures which could reduce or impede the venting capabilities.

4 A (5) A mall structure can include either an enclosed mall concourse or an open mall concourse. A mall structure may be enclosed by construction which could range from total enclosure to construction which is open, either partially or totally, to the outer air. For structures without complete walls and/or roof, the termination of the mall exit discharge would determine the extent of the structure.

5 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] General The mall structure shall be treated as a single building for the purpose of calculation of means of egress and shall be subject to the requirements for appropriate occupancies, except as modified by the provisions of ;, and the mall concourse shall be of a clear width not less than that needed to accommodate egress requirements as set forth in other sections of this Code * Open Mall Concourse Engineering Analysis. A mall concourse shall be permitted to be classified as an open mall concourse where an approved engineering analysis demonstrates that the mall concourse is designed to keep the smoke layer interface at 6 ft (1830 mm) above the highest walking level surface open to the mall concourse, for a period equal to 1.5 times the calculated egress time or 20 minutes, whichever is greater. Supplemental Information File Name A docx Description Submittal Date: Mon Aug 01 14:49:07 EDT 2016 Response Message: New section sets performance criteria which can be used to define an open mall concourse in order to apply the new provisions for open mall concourses, as newly defined, throughout The performance criteria is based on other engineering analyses in the code such as atria.

6 A Multiple fire scenarios may need to be considered to evaluate overall tenability of the mall concourse space. See Section 5.5.

7 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] * Pedestrian Way Travel Distance. The mall concourse shall be permitted to be considered a pedestrian way, provided that the criteria of and are met The travel distance within a tenant space to an exit or to the mall concourse shall not exceed the maximum travel distance permitted by the occupancy chapter An additional 200 ft (61 m) shall be permitted for travel through the enclosed mall concourse space or 300 ft (91 m) for travel through the open mall concourse, provided that all the following requirements are met: (1)* The mall concourse shall be of a clear width not less than that needed to accommodate egress requirements, as set forth in other sections of this chapter, but shall be not less than 20 ft (6100 mm) wide in its narrowest dimension. (2) On each side of the mall floor area, the mall concourse shall be provided with an unobstructed exit access of not less than 10 ft (3050 mm) in clear width parallel to, and adjacent to, the mall tenant front. (3)* The exit access specified in (2) shall lead to an exit having a width of not less than 66 in. (1675 mm). (4) The mall concourse, and all buildings connected thereto, except open parking structures, shall be protected throughout by an approved, supervised automatic sprinkler system in accordance with (1), which shall be installed in such a manner that any portion of the system serving tenant spaces can be taken out of service without affecting the operation of the portion of the system serving the mall concourse. (5)* Walls dividing tenant spaces from each other shall have a fire resistance rating of not less than 1 hour, and all of the following also shall apply: (a) (b) The partition shall extend to the underside of the ceiling or to the floor or roof or floor deck above. No separation shall be required between a tenant space and the mall concourse. (6)* Mall concourses with a floor opening connecting more than two levels shall be provided with a smoke control system. Supplemental Information File Name A _1_.docx Description Submittal Date: Mon Aug 01 14:52:24 EDT 2016 The concept of pedestrian way was used in the code to prevent the mall concourse from being enforced as a corridor. The term pedestrian way is not defined in the Code and is not used in any other provisions in Section Section includes provisions for travel distance within the tenant space and the mall concourse area so the change in title reflects the requirements. The change more clearly coordinates with title and application of new terminology in this chapter and those used by current industry standards : The code has other scenarios where additional travel is permitted in exterior environments, or scenarios where extra protection features offer additional safety to occupants. The travel distance extension here represents a similar principle with comparable hazards and

8 of 28 9/20/2016 4:01 PM conditions (example: where special provisions have been made for the control and removal of smoke and products of combustion such as smoke protected assembly seating ( /13), outdoor stadia, facilities with exterior exit access and egress components which are open to the outside air). The new definition of open mall concourse provides support for increase in travel distance. A (1): New annex reference sends users to a section in the general mercantile on wheeled carts or kiosks obstructing a means of egress to assist in enforcing the clear width (5): Consistent terminology from Chapter 8 and definition. Without deck the demarcation is left up to the AHJ. Clarifies the termination point of the partition. Has to extend to the finished deck of the roof or floor. Response Message:

9 A (1) See Section

10 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] Dead ends not exceeding a length equal to twice the width of the mall concourse for enclosed mall concourses or two and a half times the width of the mall concourse for open mall concourses, measured at the narrowest location within the dead-end portion of the mall concourse, shall be permitted. Submittal Date: Mon Aug 01 15:00:27 EDT 2016 The increase in dead end travel compares to other occupancies that allow from 20 to 50 ft. Many occupancies allow a 20 ft dead end in nonsprinklered buildings and an increase to 50 ft where the building is protected throughout by an automatic sprinkler system. This proposed increase in dead end travel for open mall concourses represents the specific hazards associated with open mall concourses based upon the new definition proposed for open mall concourses. The change coordinates with other occupancies where special arrangements have been provided to prevent for the accumulation of smoke in the means of egress. Response Message:

11 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] * Emergency lighting shall be provided in accordance with Supplemental Information File Name A docx Description Submittal Date: Mon Aug 01 21:20:26 EDT 2016 Response Message: A pointer back to the core chapter section on emergency lighting reminds users about the application of emergency lighting. The means of egress including exit access and exit discharge will need to be defined based on whether the structure is being enforced as an open mall concourse or an enclosed mall concourse.

12 A For the purposes of emergency lighting the open mall concourse should be considered a component of the means of egress. See Section

13 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] Emergency Forces Notification. Emergency forces notification shall be provided and shall include notifying all of the following: (1) Fire department in accordance with (2) Local Approved, local emergency organization, if provided Submittal Date: Mon Aug 01 15:13:30 EDT 2016 Response Message: The local emergency organization should also be approved by the Authority Having Jurisdiction. The language is consistent with NFPA 5000.

14 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ New Section after ] Risk Analysis for Mass Notification. Mall structures shall conduct a risk analysis to determine the need for a mass notification system in accordance with Section Submittal Date: Mon Aug 01 12:20:21 EDT 2016 Response Message: After the First Draft meeting a task group was established to develop text for if and when the new provisions of Section 9.14 should apply to mercantile and business occupancies. After multiple meetings of the task group as well as input from the full committee the proposed text identifies mall structures as appropriate mercantile occupancies for requiring a risk analysis to determine if a mass notification system is required. Mall structures are large structures that incorporate a number of different tenant uses and tend to have a higher occupant load. There have been multiple recent events in mall structures that would support the requirement for a risk analysis for mass notification systems. These systems can provide real time communication and response to the occupants.

15 0 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] Kiosks. Kiosks and similar structures (temporary or permanent) shall not be considered tenant spaces and shall meet all of the following requirements: (1) Combustible kiosks and similar structures shall be constructed of any of the following materials: (a) Fire-retardant-treated wood complying with the requirements for fire-retardant-impregnated wood in NFPA 703, Standard for Fire Retardant Treated Wood and Fire-Retardant Coatings for Building Materials (b) Light-transmitting plastics complying with the building code (c) Foamed plastics having a maximum heat release rate not greater than 100 kw when tested in accordance with ANSI/UL 1975, Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes, or in accordance with NFPA 289, Standard Method of Fire Test for Individual Fuel Packages, using the 20 kw ignition source (d) Metal composite material (MCM) having a flame spread index not greater than 25 and a smoke developed index not greater than 450 in accordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials, when tested as an assembly in the maximum thickness intended for use (e) Textiles and films meeting the flame propagation performance criteria contained in NFPA 701, Standard Methods of Fire Tests for Flame Propagation of Textiles and Films Kiosks or similar structures located within the mall concourse shall be protected with approved fire suppression and detection devices. (2) The minimum horizontal separation between kiosks, or groups of kiosks, and other structures within the mall concourse shall be 20 ft (6100 mm). (3) Each kiosk, or group of kiosks, or similar structure shall have a maximum area of 300 ft 2 (27.8 m 2 ). Submittal Date: Mon Aug 01 15:14:27 EDT 2016 Response Message: Provisions for the protection of kiosks have been moved to Section for extinguishing systems which retains the extinguishment provisions in same section.

16 1 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] * Smoke Control. Smoke control in accordance with Section 9.3 and complying with 8.6.7(5) shall be provided in a an enclosed mall concourse with floor openings connecting more than two levels stories. Submittal Date: Mon Aug 01 15:16:58 EDT 2016 This proposed change to mandate smoke control only for enclosed mall concourses connecting more than two levels represents the specific hazards associated with open versus enclosed mall concourses based upon the new definition proposed for open mall concourses. The change coordinates with other occupancies and other changes within the mall section where special arrangements have been provided to prevent for the accumulation of smoke in the means of egress.

17 2 of 28 9/20/2016 4:01 PM Second Revision No NFPA [ Section No ] Automatic Extinguishing Systems The mall structure and all anchor buildings shall be protected throughout by an approved, supervised automatic sprinkler system in accordance with (1) and through The system shall be installed in such a manner that any portion of the system serving tenant spaces can be taken out of service without affecting the operation of the portion of the system serving the mall concourse * Any shade structures, canopies, awnings, or similar structures in the open mall concourse shall be protected by an approved, supervised automatic sprinkler system in accordance with Section * Kiosks or similar structures located within the enclosed mall concourse shall be protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7. Supplemental Information File Name A docx A docx Description Submittal Date: Mon Aug 01 15:42:52 EDT and Annex: Many open mall concourses contain shade structures and other features that may necessitate the need for automatic sprinkler protection. The proposed languages points user to the applicable section of Chapter 9 and then to NFPA 13 for the necessary guidance on how to protect these features : This text was formerly located in the section specifically for kiosks and is being relocated here to keep requirements for extinguishment in one section; makes the section more user friendly. Response Message:

18 A Examples of these roof type structures include but are not limited to shade structures, canopies, awnings or other similar structures located above the open mall concourse which serve as a screen or shelter from the sun, rain, or other atmospheric and climatological effects. However, these structures are designed to only partially enclose the area above a mall concourse, allow the mall concourse to be open to the atmosphere, and not serve as roof that is designed to separate the conditioned space of the mall concourse from the exterior atmosphere. These structures are permitted to be supported by the mall building, mall concourse walls, or can be self-supporting. It is intended that these structures be protected by a supervised automatic sprinkler system where required by NFPA 13 unless allowed to be omitted with approval of the AHJ.

19 A Sprinklers may be omitted in kiosks located in portions of open mall concourses where no roof exists. Where sprinklers are provided at the mall concourse ceiling, the obstruction provisions of NFPA 13 also apply.
