  • Ensure covers or railings protecting temporary access openings are secured in place at all times when an opening is not being used.
  • Provide readily visible warning signs that clearly display the nature of the hazard and any protective action required.
  • Wear fall protection where there is a danger of falling.
  • Establish and discuss safe work procedures. Identify and control all hazards to finish the job safely.
  • Train all persons, especially workplace examiners, to recognize and understand safe job procedures before beginning work. Communicate and correct hazards in a timely manner.
