Intent | Intent 1: To limit the probability that persons will not have a choice
of an alternative egress route in the case of one route to an exit being blocked
or obstructed in an emergency situation, which could lead to delays in the

to persons. Intent 2: To limit the probability that two alternative access routes
to a floor area from exits will be simultaneously blocked or obstructed in
an emergency situation, which could lead to emergency responders being delayed
in gaining access to a floor area, 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.
