| Intent | Intent 1: To exempt egress facilities serving a dwelling unit from
the requirements of Sentences 3.3.1.3.(8) and (9), and 3.3.1.9.(7) which
would otherwise:
This is on the basis that there is a second
means of egress from the dwelling unit available if the route through a means
of egress leading to the exit is impeded, blocked, or untenable.
This is to limit the probability that persons will not have the
choice of an alternative egress route in the case where one route is blocked
or obstructed in an emergency situation, which could lead to delays in the
evacuation or movement of persons to a safe place, which could lead to harm
to persons.
