OS3 Safety in Use



Intent 1:

To limit the probability that excessive variance in the configuration of a flight will disrupt the gait of users, which could lead to:

  • persons misstepping and tripping, which could lead to harm to persons, or
  • persons misstepping and tripping in an emergency -- when traffic flow is expected to be limited owing to the presence of exit stairs as an alternate option -- which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
