Gross
area shall be the area of the floor within the inside perimeter of the outside
walls of the floor of the building under consideration with no deductions for
corridors and passage-ways, stairs, closets, thickness of interior walls,
columns, lifts and building shafts or other features. However the proponent may
consider the area including the outside wall thickness, if he so desires. All
factors expressed are in gross area unless marked net.
(2)
Occupant
load in dormitory portions of homes for the aged, orphanages, insane asylums,
etc, where sleeping accommodation is provided, shall be calculated at not less
than 7.5 m2 gross floor area per person.
(3)
These
shall include gymnasium, table tennis room, billiard room and other gaming
rooms, library, swimming pool and like.

parking areas under occupancy other than storage shall also be 30 square meter
per person.
15.9. Exit
Requirements:-
15.9.1.

emergency as per clauses 4.2 to 4.4.2.5 of Part 4 of the National Building Code
of India, 2016/this part of regulations.
15.9.2.
General Requirements:-
The
following general requirements shall apply to exits.-
(a)
Unless
otherwise specified, lifts, escalators, moving walks and revolving doors shall
not be considered as exits and shall not constitute any part of the required
exit.
(b)
Every
exit, exit passageway and exit discharge shall be continuously maintained free
of all obstructions or impediments to full use in the case of fire or other
emergency.
(c)
Every
building having human occupancy shall be provided with exits sufficient to
permit safe egress of occupants in case of fire or other emergency.
(d)
In
every building or structure, exits shall comply with the minimum requirements
of this Part of regulations, except those not accessible for general public
use.
(e)
No
building shall be so altered as to reduce the number, width or protection of
exits to less than that required.
(f)
For
non-naturally ventilated areas, fire doors with 120 minutes fire resistance
rating shall be provided and particularly at the entrance to lift lobby and
stair well where a funnel or flue effect may be created, inducing an upward
spread of fire, to prevent spread of fire and smoke.
(g)
Exits
shall be so arranged that they may be reached without passing through another
occupied unit/passage in others control, if they pose challenge or restriction
in means of egress.
(h)
Doors
in exits shall open in the direction of exit. In case of Group D Assembly
Buildings and Group C Institutional Buildings (Subdivision C-1 Hospitals and
sanatoria), exit door shall not open immediately upon a flight of stair and all
such entries to the stair shall be through a landing, so that such doors do not
impede movement of people descending from a higher floor when fully opened (see
Sketch No. 8 A). While for other occupancies, such doors shall not reduce the
pathway in the landing by more than half the width of such staircase (see
Sketch No. 8 B). Overhead or sliding doors shall not be installed.
(i)
At
least half of the required exit stairs from upper floors (rounded to the next
higher number) shall discharge directly to the exterior or through exit
passageways.
(j)
Unless
otherwise specified, all the exits and exit passageways to exit discharge shall
have a clear ceiling height of at least 2.4 meter. However, the height of exit
door shall be at least 2.0 meter (see Sketch No. 9.)
(k)
Where
changes in elevation of more than 300 mm are encountered in the exits, ramps or
sloped surfaces shall be used with handrails and floor finish materials that
contrast with the adjacent finish materials.
(l)
The
capacity of the means of egress required from any storey of the building shall
not be reduced along the path of egress travel until arrival to the exit
discharge.
(m)
The
lifts, escalators, moving walks, turnstiles and revolving doors shall not be
considered in determining the required capacity of means of egress for the
individual floors or the building.
(n)
Turnstiles
or similar devices that restrict travel to one direction or that are used to
restrict unauthorized entry shall not be so placed as to obstruct any required
means of egress. Alternative door openings of required exit width shall be
available within 3 meter of such devices, if installed.
(o)
Suitable
means shall be provided so that all access controlled exit doors, turnstiles,
boom barriers and other such exits shall automatically operate to open mode
during emergencies like fire, smoke, acts of terrorism, etc, so that people can
safely and quickly egress into safe areas outside. If required, a master
controlling device may be installed at a strategic location to achieve this.
(p)
Penetrations
into and openings through an exit are prohibited except those necessary like
for the fire protection piping, ducts for pressurization and similar life
safety services. Such openings as well as vertical passage of shaft through
floors shall be protected by passive systems.
(q)
Walking
surfaces in exit access shall comply with the following requirements for smooth
exit:

Slope
perpendicular to the direction of travel shall not exceed 1 in 48.
(iv)
Walking
surfaces shall be slip resistant along the entire path of travel.
15.9.3.
Number of Exits:- The minimum required number of exits in a building shall be
determined based on occupant load (see Table XXI as specified in regulation
15.8.1) and width required per person (see Table XXII as specified in
regulation 15.9.5) as appropriate to the type of exit for respective
occupancies, subject to complying with maximum travel distance requirement (see
Table XXIII as specified in regulation 15.9.6).
15.9.4.
Arrangement of Exits:-
(a)
Exits
shall be so located that the travel distance on the floor shall not exceed the
distance given in Table XXIII as specified in regulation 15.9.6.
(b)
Travel
distance shall be measured from the most remote point within a storey or a
mezzanine floor along the natural and un-obstructed path of horizontal or
vertical egress travel to the door to an exit.
(c)
The
dead end corridor length in exit access shall not exceed 6 meters for
educational, institutional and assembly occupancies. For other occupancies, the
same shall be 15 meter (see Sketch No. 11.).
(d)
Exits
shall be placed as remote from each other as possible and shall be arranged to
provide direct access in separate directions from any point in the area served.
15.9.5.
Capacity of Exits:-
(a)
Exit
capacity is the number of people that can pass through a stairway, level
components (door and corridor) and ramps.
The
total capacity of all the respective means of egress serving a floor shall be
sufficient to allow egress of the entire population of the floor.
(b)
The
unit of exit width, used to measure the capacity if any exit, shall be 500 mm. A
clear width of 250 mm shall be counted as an additional half unit. Clear width
less than 250 mm shall not be counted for exit width.
(c)
Width
per person for stairways, level components and ramps shall be determined using
the capacity factors in accordance with Table XXII.
Note:
If an exit doorway measures 1,000 mm in clear width, it would be defined as
providing exit capacity for 1,000/6.5 occupants, that is, 153 persons (say 150
persons) and number of such exit doorways can then be calculated depending on the
occupant load.

When
calculating stairways, level components and ramps and other exit means, the
capacity of the entire system shall have to be based upon the minimum capacity
available from any part of the system. The corridor, if so provided shall also
to be planned with consideration of exit access adequacy for the number of
occupants. Further, the situation of doors opening to an exit stairway shall be
considered. If the stairway provides an exit capacity of 150 persons, and the
doors leading into the stairway provide an exit capacity of 153 persons, the
overall exit system would be considered to provide the minimum exit capacity of
only 150 persons afforded by the stairway. The exit planning will be limited by
the most restrictive exit calculation under the means of egress.
(e)
In
the procedures for determining required egress capacity, the number of required
means of egress is based on a floorby-floor consideration, rather than the
accumulation of the occupancy loads of all the floors. However, the number of
means of egress cannot decrease as an occupant proceeds along the egress path.
15.9.6.
Types of Exit access and exits:-
Various
types of exit access and exits are doorways, corridors and passageways,
horizontal exits, internal staircases, exit passageways, external staircases
and ramps.
