Intent 1:

To limit the probability of an inadequate clear surface for users to adjust their gait when entering or exiting a flight of stairs, or for users to turn to negotiate a doorway in a stairway, which could lead to:

  • persons falling, or
  • persons falling in an emergency, which could lead to delays in the evacuation or movement of persons to a safe place.

This is to limit the probability of harm to persons.
