(a) The step specified in A.36.2.2.7.2(3) normally sends a portion or all (per 36.4.4.3.4) of the tenant space’s occupant load into the mall. (b) Any remaining occupants are sent through the back of the tenant space into an exit passageway that might serve multiple tenant spaces and the mall. (4) The width of the exit passageway is required to be sized for the most restrictive of the following: (a) Width of not less than 66 in. (1675 mm) per 36.4.4.2.2(3) (b) Portion of the egress capacity from the largest single tenant space being served by the exit passageway (c) Portion of the egress capacity from the mall being provided by the exit passageway The concepts used in A.36.2.2.7.2(4)(a) through (c) include the following: (1) After proper egress capacity is provided for the mall/pedestrian way, each tenant space is then required to independently provide egress capacity for its occupants. (2) The mall required exit passageway width and the tenant space required exit passageway width are not required to be added together. (3) The required exit passageway width for a tenant space is not required to be added to that of other tenant spaces using the same exit passageway. A.36.2.5.10 To eliminate the obstruction to the means of egress of the interior exit access and the exterior exit discharge, it is the intent to provide adequate area for transit and parking of wheeled carts or buggies used by customers. This area includes corral areas adjacent to exits that are constructed to restrict the movement of wheeled carts or buggies therefrom. A.36.2.7.2 The basis for the exemption to the general rule on complete enclosure of exits up to their point of discharge to the outside of the building is that, with the specified safeguards, reasonable safety is maintained. A stairway is not considered to discharge through the street floor area if it leads to the street through a fire resistance–rated enclosure (exit passageway) separating it from the main area, even though there are doors between the first-floor stairway landing and the main area. The provisions of 36.2.7.2 should not be confused with those for open stairways, as permitted by 36.3.1(1). A.36.3.2.1 It is the intent to permit a suspended natural gas–fired unit heater that complies with the requirements of 9.2.2 to be installed and used in a mercantile occupancy without classifying the area in which it is located as hazardous. A.36.3.2.1.1 These areas can include, but are not limited to, areas used for general storage, boiler or furnace rooms, and maintenance shops that include woodworking and painting areas. A.36.3.2.2 The requirement for separating high hazard contents areas from other parts of the building is intended to isolate the hazard, and 8.2.3.3 is applicable.


A.36.3.2.3 It is not the intent to prohibit the use of equipment that is used less frequently and does not produce significant grease grease-laden vapors such as that equipment used for cooking demonstrations. A.36.3.6.1 The intent of 36.3.6.1(2) and (3) is to permit spaces within single tenant spaces, or within buildings protected throughout by an approved, supervised automatic sprinkler system, to be open to the exit access corridor without separation.

A.36.4.4.2.2(5) Mall Building. A mall building might enclose one or more uses, such as retail and wholesale stores, drinking and dining establishments, entertainment and amusement facilities, transportation facilities, offices, and other similar uses. A.36.4.4.24.2(3) The minimum requirement for terminating mall exit access in not less than 66 in. (1675 mm) of egress width relates to the minimum requirement for not less than one aisle in Class A

mercantile occupancies with 30,000 ft2 (2800 m2) or greater sales area to be 60 in. (1525 mm) in width. A.36.4.4.24.2(5) Walls providing tenant separations are only required to extend to the underside of the ceiling assembly, regardless of the ceiling's fire-resistive rating. If a ceiling is not provided in either of the tenant spaces, then the wall should extend to the underside of the roof or floor above. A.36.4.4.24.2(6) Fire experience in mall shopping centers indicates that the most likely place of fire origin is in the tenant space, where the combustible fire load is far greater than in the mall. Furthermore, any fires resulting from the comparatively low fire load in the mall are more likely to be detected and extinguished in their incipient stages. Early detection is likely due to the nature of the mall as a high-traffic pedestrian way. Such fires produce less smoke development in a greater volume of space than fires in the more confined adjacent tenant space. Smoke control systems that address fire experience in malls are necessary to ensure the integrity of the mall as a pedestrian way by maintaining it reasonably free of the products of combustion for a duration not less than that required to evacuate the area of the building that is affected by the fire. Secondary considerations should include the following: (1) Confinement of the products of combustion to the area of origin (2) Removal of the products of combustion, with a minimum of migration of such products of combustion from one tenant space to another (3) Achievement of evacuation without the need for smoke control in one- and two-level mall buildings protected by automatic sprinklers Systems, or combinations of systems, that can be engineered to address fires in malls of three or more levels include the following: (1) Separate mechanical exhaust or control systems (2) Mechanical exhaust or control systems in conjunction with heating, ventilating, and air-conditioning systems (3) Automatically or manually released gravity roof vent devices, such as skylights, relief dampers, or smoke vents (4) Combinations of items (1), (2), and (3) in this list, or any other engineered system designed to accomplish the purpose of this section A.36.4.4.36.5 It is not the intent of 36.4.4.36.5 to require that large tenant spaces be considered anchor stores. A tenant space not considered in determining the occupant load of the mall is required to be arranged so that all of its means of egress will be independent of the mall. A.36.4.4.47.3.2 It is the intent to permit the omission of visible alarm notification appliances from the mall or pedestrian way in mall buildings. It is anticipated that occupants with hearing impairments will receive cues from other building occupants and respond accordingly. Visible signals should be provided in public restrooms and other adjunct spaces in the mall subject to occupancy solely by persons with hearing impairments. A.36.4.4.69.2 Rooms opening onto the exit passageway are intended to include building service elevators, elevator machine rooms, electrical rooms, telephone rooms, janitor closets, restrooms, and similar normally unoccupied spaces not requiring hazardous area protection in accordance with Section 8.7.

(3) The required exit passageway width for a tenant space is not required to be added to that of other tenant spaces using the same exit passageway. A.37.2.5.2 The purpose of 37.2.5.2 is to avoid pockets or dead ends of such size that they pose an undue danger of persons becoming trapped in case of fire. It is recognized that dead ends exceeding the permitted limits exist and, in some cases, are impractical to eliminate. The authority having jurisdiction might permit such dead ends to continue to exist, taking into consideration any or all of the following: (1) Tenant arrangement (2) Automatic sprinkler protection (3) Smoke detection (4) Exit remoteness A.37.2.5.3 It is recognized that common paths of travel exceeding the permitted limits exist and, in some cases, are impractical to eliminate.

Secondary considerations should include the following: (1) Confinement of the products of combustion to the area of origin (2) Removal of the products of combustion, with a minimum of migration of such products of combustion from one tenant space to another (3) Achievement of evacuation without the need for smoke control in one- and two-level mall buildings protected by automatic sprinklers Systems, or combinations of systems, that can be engineered to address fires in malls of three or more levels include the following: (1) Separate mechanical exhaust or control systems (2) Mechanical exhaust or control systems in conjunction with heating, ventilating, and air-conditioning systems (3) Automatically or manually released gravity roof vent devices, such as skylights, relief dampers, or smoke vents (4) Combinations of items (1), (2), and (3) in this list, or any other engineered system designed to accomplish the purpose of this section A.37.4.4.36.5 It is not the intent of 37.4.4.36.5 to require that large tenant spaces be considered anchor stores. A tenant space not considered in determining the occupant load of the mall is required to be arranged so that all of its means of egress will be independent of the mall. A.37.4.4.69.2 Rooms opening onto the exit passageway are intended to include building service elevators, elevator machine rooms, electrical rooms, telephone rooms, janitor closets, restrooms, and similar normally unoccupied spaces not requiring hazardous area protection in accordance with Section 8.7. A.38.1.3.2.2(4) Means to prevent spilled fuel from accumulating and entering the business occupancy building can be by curbs, scuppers, special drainage systems, sloping the floor away from the door openings, or elevation differences not less than 4 in. (100 mm). A.38.2.2.2.2 The words “principal entrance/exit doors” describe doors that the authority having jurisdiction can reasonably expect to be unlocked in order for the facility to do business. A.38.2.3.2 It is not the intent that this provision apply to noncorridor or nonpassageway areas of exit access, such as the spaces between rows of desks created by office layout or low-height partitions.

A.38.3.2.1 It is not the intent of this provision that rooms inside individual tenant spaces that are used to store routine office supplies for that tenant be required to be either separated or sprinklered. A.38.3.2.2 The requirement for separating high hazard contents areas from other parts of the building is intended to isolate the hazard, and 8.2.3.3 is applicable.


A.38.3.2.3 It is not the intent to prohibit the use of equipment that is used less frequently and does not produce significant grease grease-laden vapors such as that equipment used for cooking demonstrations. A.38.3.6.1 The intent of 38.3.6(1) through (3) is to permit spaces to be open to the exit access corridor without separation. A.38.3.6.1(1) Where exits are available from an open floor area, such as open plan buildings, corridors are not required to be separated. An example of an open plan building is a building in which the work spaces and accesses to exits are delineated by the use of tables, desks, bookcases, or counters, or by partitions that are less than floor-to-ceiling height. A.38.3.6.1(2) It is the intent of this provision that a single tenant be limited to an area occupied under a single management and work the same hours. The concept is that people under the same employ working the same hours would likely be familiar with their entire tenant space. It is not the intent to apply this provision simply because tenants are owned by the same organization. For example, in a government-owned office building, the offices of different federal agencies would be considered multiple tenants, because an employee normally works for one agency. The agencies might work various hours. Another example of multiple tenancy would be a classroom building of a university, because some classrooms might be in use at times when other classrooms are not being used. A.39.1.3.2.2(4) Means to prevent spilled fuel from accumulating and entering the business occupancy building can be by curbs, scuppers, special drainage systems, sloping the floor away from the door openings, or elevation differences not less than 4 in. (100 mm). A.39.2.2.2.2 The words “principal entrance/exit doors” describe doors that the authority having jurisdiction can reasonably expect to be unlocked in order for the facility to do business. A.39.2.5.2 It is recognized that dead ends exceeding the permitted limits exist and, in some cases, are impractical to eliminate. The authority having jurisdiction might permit such dead ends to continue to exist, taking into consideration any or all of the following: (1) Tenant arrangement (2) Automatic sprinkler protection (3) Smoke detection (4) Exit remoteness A.39.2.5.3 It is recognized that common paths of travel exceeding the permitted limits exist and, in some cases, are impractical to eliminate. The authority having jurisdiction might permit such common paths of travel to continue to exist, taking into consideration any or all of the following: (1) Tenant arrangement (2) Automatic sprinkler protection (3) Smoke detection (4) Exit remoteness A.39.3.2.1 It is not the intent of this provision that rooms inside individual tenant spaces that are used to store routine office supplies for that tenant be required to be separated or sprinklered. A.39.3.2.2 The requirement for separating high hazard contents areas from other parts of the building is intended to isolate the hazard, and 8.2.3.3 is applicable.

A.39.3.2.3 It is not the intent to prohibit the use of equipment that is used less frequently and does not produce significant grease grease-laden vapors such as that equipment used for cooking demonstrations. A.39.4.2.2 In some cases, appreciable cost might be involved in bringing an existing occupancy into compliance. Where this is true, it would be appropriate for the authority having jurisdiction to prescribe a schedule determined jointly with the facility, allowing suitable periods of time for the correction of the various deficiencies and giving due weight to the ability of the owner to secure the necessary funds.
