Intent

Intent 1:

To limit the probability that obstructions in an exit will reduce the exit width, which could lead to:

  • insufficient width to permit efficient egress 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, and
  • emergency responders being delayed in gaining access to floor areas in an emergency situation, which could lead to delays or ineffectiveness in emergency response operations, 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 limit the probability that fixtures, turnstiles or construction projecting into, or fixed within, an exit will lead to collision, tripping, falling or other risks of injuries, which could lead to harm to persons.
