Intent

Intent 1:

To limit the probability that fire or smoke will spread into the lobby from an elevator shaft, which could lead to untenable conditions in the exit, 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 supersede the application of Sentence 9.9.8.5.(3) by allowing elevator doors to open onto certain lobbies, on condition that elevator doors remain normally closed, which should provide adequate separation in the event of a fire.
