Intent 1:
To limit the probability that because of the absence
of a solid riser
- persons wearing leg braces or prosthetic devices will
not able to guide their foot up over the riser to the next step and
- persons using canes or crutches will not be able to
place them against the riser to maintain balance,
which could lead to the person not being able to circulate
within a building without the assistance of another person.
