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.
