same fire resistance rating and opening protective fire protection rating as those required for the stair enclosure.
[101:7.2.6.3]
The width of an exit passageway shall be sized to accommodate the aggregate required capacity of all exits that discharge through it, unless one of the following conditions applies:
* Where an exit passageway serves occupants of the level of exit discharge as well as other stories, the capacity shall not be required to be aggregated.
As provided in Chapters 36 and 37 of NFPA 101, an exit passageway in a mall structure shall be permitted to accommodate occupant loads independently from the mall concourse and the tenant spaces. (See 36.2.2.7.2 and 37.2.2.7.2 of NFPA 101.)
In new construction, the minimum width of any exit
passageway into which an exit stair discharges, or that serves as
a horizontal transfer within an exit stair system, shall meet the
following criteria:
The minimum width of the exit passageway shall be not
less than two-thirds of the width of the exit stair.
Where stairs are credited with egress capacity in accordance with 14.8.3.2, the exit passageway width shall be
sized to accommodate the same capacity as the stair, with
such capacity determined by use of the capacity factors in
Table 14.8.3.1.
The total capacity of the means of egress for any
story, balcony, tier, or other occupied space shall be sufficient
for the occupant load thereof unless one of the following
conditions exists:
The AHJ shall be permitted to establish the occupant
load as the number of persons for which existing means
of egress is adequate, provided that measures are established to prevent occupancy by a greater number of
persons.
The egress capacity shall have been previously approved
as being adequate.
The occupant load in any building or portion thereof shall be not less than the number of persons determined by dividing the floor area assigned to that use by the occupant load factor for that use as specified in Table 14.8.1.2, Figure 14.8.1.2(a), and Figure 14.8.1.2(b). Where both gross and net area figures are given for the same occupancy, calculations shall be made by applying the gross area figure to the gross area of the portion of the building devoted to the use for which the gross area figure is specified and by applying the net area figure to the net area of the portion of the building devoted to the use for which the net area figure is specified. [101:7.3.1.2]
MP: The occupant load is the maximum probable number of occupants present at any time.
aAll factors are expressed in gross area unless marked "net."
bSee A.14.8.1.2.
cFor determining occupant load in mercantile occupancies where, due to differences in the finished ground level of streets on different sides, two or more floors directly accessible from streets (not including alleys or similar back streets) exist, each such floor is permitted to be considered a street floor. The occupant load factor is one person for each 40 ft2 (3.7 m2) of gross floor area of sales space.
eFor any food court or other assembly use areas located in the mall concourse that are not included as a portion of the gross leasable area of the mall structure, the occupant load is calculated based on the occupant load factor for that use as specified in Table 14.8.1.2. The remaining mall concourse area is not required to be assigned an occupant load.
fThe portions of the mall concourse not used as gross leasable area are not required to be assessed an occupant load based on Table 14.8.1.2. However, means of egress from a mall concourse are required to be provided for an occupant load determined by dividing the gross leasable area of the mall building (not including anchor buildings) by the appropriate lowest whole number occupant load factor from Figure 14.8.1.2(a) or Figure 14.8.1.2(b).
Each individual tenant space is required to have means of egress to the outside or to the mall concourse based on occupant loads calculated by using the appropriate occupant load factor from Table 14.8.1.2.
Each individual anchor store is required to have means of egress independent of the mall concourse.
The occupant load in any building or portion
thereof shall be permitted to be increased from the occupant
load established for the given use in accordance with 14.8.1.2
where all other requirements of this Code are also met, based
on such increased occupant load. [101:7.3.1.3.1]
The AHJ shall be permitted to require an approved
aisle, seating, or fixed equipment diagram to substantiate any
increase in occupant load and shall be permitted to require
that such a diagram be posted in an approved location.
[101:7.3.1.3.2]
Where an exit
serves more than one story, only the occupant load of each
story considered individually shall be used in computing the
required capacity of the exit at that story, provided that the
required egress capacity of the exit is not decreased in the
direction of egress travel. [101:7.3.1.4]
Where means
of egress from a story above and a story below converge at an
intermediate story, the capacity of the means of egress from the
point of convergence shall be not less than the sum of the
required capacity of the two means of egress. [101:7.3.1.5]

shall be added to the required egress capacity of the room in
which it is located. [101:7.3.1.6]
The width of means of egress shall be measured in
the clear at the narrowest point of the egress component under
consideration, unless otherwise provided in 14.8.2.2 or
14.8.2.3. [101:7.3.2.1]
Projections within the means of egress of not more
than 41/2 in. (114 mm) on each side shall be permitted at a
height of 38 in. (965 mm) and below. In the case of stair and
landing handrails forming part of a guard, in accordance with
7.2.2.4.5.3 of NFPA 101, such projections shall be permitted at
a height of 42 in. (1065 mm) and below. [101:7.3.2.2]
Egress capacity for approved components of means of egress shall be based on the capacity factors shown in Table 14.8.3.1, unless otherwise provided in 14.8.3.2. [101:7.3.3.1]
For stairways wider than 44 in. (1120 mm) and subject to the 0.3 in. (7.6 mm) width per person capacity factor, the capacity shall be permitted to be increased using the following equation:
[14.8.3.2]
where:
C
=
capacity, in persons, rounded to the nearest integer
Wn
=
nominal width of the stair as permitted by 14.8.3.2 (in.)
The required capacity of a corridor shall be the occupant load that utilizes the corridor for exit access divided by
the required number of exits to which the corridor connects,
but the corridor capacity shall be not less than the required
capacity of the exit to which the corridor leads. [101:7.3.3.3]
The width of exit access serving not more than six people, and having a length not exceeding 50 ft (15 m) shall meet both of the following criteria:

means of egress at each story, provided that the required
number of means of egress is not decreased in the direction of
egress travel. [101:7.4.1.4]
