What is the difference between entry and exit procedures in re-entry planning?

• A. Exit procedures define how and when to leave and revert to cold zone.
• B. Entry procedures describe how to enter safely.
• C. Entry procedures describe how to enter safely; exit procedures define how and when to leave and revert to cold zone.
• D. Exit procedures are unrelated to safety during exit.

Answer: (C)

Understanding re-entry planning means recognizing that entering a potentially hazardous area and leaving it are two phases with their own safety steps. Entry procedures describe how to approach and enter the area safely, including PPE, monitoring, communications, and authorization. Exit procedures describe how and when to leave and how to revert to the cold zone, including doffing, decontamination, accountability, and returning to safe conditions. This separation matters because entering focuses on starting work without exposing people to danger, while exiting ensures contaminants are removed, everyone is accounted for, and the environment is restored to a safe state.
