which could lead to congestion at landings, 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 emergency responders will

which could lead to harm to persons. Intent 3: To limit the probability that a person exiting onto a ramp
will experience an immediate change in slope, which could lead to tripping
or falling, which could lead to harm to persons. |
