To limit the probability of insufficient clearance
between a handrail and any surface behind it, which could lead to:
- a person's hand becoming wedged or caught between the
handrail and the surface behind it, which could lead to harm to the
person, and
- a person not having a secure grip and falling, which
could lead to harm to the person.
Intent 2:
To limit the probability of insufficient clearance
between a handrail and any surface behind it, which could lead to:
- a person's hand becoming wedged or caught between the
handrail and the surface behind it when using the exit stairway or
ramp in an emergency situation, and
- a person not having a secure grip and falling, when
using the exit stairway or ramp in an emergency situation.
This is to limit the probability of
delays in the evacuation or movement of persons to a safe place, which
could lead to harm to persons.
