Intent | Intent 1: To limit the probability that egress routes from a mezzanine
will become untenable in a fire situation during the time involved in reaching
the exits accessible at mezzanine level, which could lead to delays in the
evacuation or movement of persons to a safe place, which could lead to harm
to persons. Intent 2: To clarify that mezzanines are to be provided with exits
on the same basis as required for floor areas. Intent 3: In cases where mezzanines are not included in the definition
of floor area, this expands the application of Section 3.4. to
such mezzanines. |
