| Intent | Intent 1: To supersede the requirements in Sentence 9.9.6.6.(1),
which prohibits exit doors to open directly onto a step, on the basis that
a step of limited height will minimize the danger of door blockage from ice
or snow without creating an undue risk of injury or delay. This
is to limit the probability that the accumulation of ice or snow outside the
door will block the door, which could lead to persons being unable to leave
the building 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.
