OS3 Safety in Use



Intent 1:

Where users are not likely to be familiar with the stairway or ramp, to limit the probability of an abrupt termination of a handrail at the end of a flight of stairs, which could lead to an inability to establish or maintain a grasp on the handrail when making a transition to or from stairs, 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.
