Application 2: This also applies to certain mezzanines,
as stated in Sentence 9.9.8.6.(1).

Intent | Intent 1: To limit the probability that an excessive portion of the
required exiting capacity will be concentrated at one location, which could
lead to insufficient width in other exits to permit efficient egress in an
emergency situation if the exit becomes obstructed or inaccessible, which
could lead to delays in the evacuation or movement of persons to a safe place,
which could lead to harm to persons. |
