How often must entry permits be updated during normal working hours?

• A. Every hour
• B. During normal working hours
• C. At the end of each shift change
• D. When changes occur

Answer: (C)

Entry permits are part of a permit-to-work system, and the best practice during normal operations is to refresh and reissue them at shift changes. This end-of-shift update ensures the incoming crew starts with a current picture of hazards, controls, and restricted areas, and it confirms who is authorized to work and what tasks are allowed. It also captures any changes that occurred during the previous shift, so responsibilities and precautions are clearly transferred. Waiting for changes to happen or updating only on an hour-by-hour basis isn’t as reliable for handover and can lead to misunderstandings about current conditions. Regular handover updates maintain continuity, accountability, and safety.
