Intent | Intent 1: To limit the probability that persons will enter a dead
end portion of a corridor during an emergency situation and be prevented from
retracing their steps as a result of crowd pressure or untenable conditions,
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 exempt a corridor entirely within a suite from the requirement
in the remainder of the Sentence which restricts the length of dead end portions
on the basis that the occupants are familiar with the suite arrangement and
are expected to make appropriate decisions in an emergency. |
