(a) General. — The construction of stairs and exits

shall conform to the occupant load requirements of buildings, reviewing

stands, bleachers and grandstands:

:red

(1) Determinations of Occupant Loads. — The Occupant

load permitted in any building or portion thereof shall be determined

by dividing the floor area assigned to that use by the unit area

allowed per occupant as determined by the Secretary.

(2) Exit Requirements. — Exit requirements of a

building or portion thereof used for different purposes shall be

determined by the occupant load which gives the largest number of

persons. No obstruction shall be placed in the required width of an

exit except projections permitted by this Code.

(3) Posting of Room Capacity. — Any room having an

occupant load of more than 50 where fixed seats are not installed, and

which is used for classroom, assembly, or similar purpose shall have

the capacity of the room posted in a conspicuous place near the main

exit from the room.

(4) Changes in Elevation. — Except in Groups A

Occupancies, changes in floor elevations of less than 300 millimeters

along any exit serving a tributary occupant load of 10 or more shall be

by means of ramps.

(b) Exits

(1) Number of Exits. — Every building or usable

portion thereof shall have at least one exit. In all occupancies,

floors above the first storey having an occupant load of more than 10

shall not have less than two exits. Each mezzanine floor used for other

than storage purposes, if greater in area than 185 square meters or

more than 18.00 meters in any dimension, shall have at least than two

stairways to an adjacent floor. Every storey or portion thereof, having

an occupant load of 500 to 999 shall have at least three exits. Every

storey or portion thereof having an occupant load of 1000 or more shall

have at least four (4) exits. The number of exits required from any

storey of a building shall be determined by using the occupant loads of

floors which exit through by using the occupant loads of floors which

exit through the level under consideration as follows: 50 percent of

the occupant load in the first adjacent storey above (and the first

adjacent storey below, when a storey below exits through the level

under consideration) and 25 percent of the occupant load in the storey

immediately beyond the first adjacent storey. The maximum number of

exits required for any storey shall be maintained until egress is

provided from the structures. For purposes of this Section basement or

storeys. Floors above the second storey, basements and cellars used for

other than service of the building shall have not less than two exits.

width of exits shall be divided approximately equally among the

separate exits. The total exit width required from any storey of a

building shall be determined by using the occupant load of that storey

plus the percentage of the occupant loads of floors which exits through

the level under consideration as follows: fifty (50) per cent of the

occupant load in the first adjacent storey above (and the first

adjacent storey below when a storey below exits through the level under

consideration) and twenty five per cent of the occupant load in the

storey immediately beyond the first adjacent storey. The maximum exit

width from any storey of a building shall be maintained.
