When should the RCS authorize entry under the Re-Entry Permit?

• A. Before any entry, verify that PPE is present.
• B. After a brief visual inspection of the site.
• C. Only after confirming all specified entry conditions are met and hazards mitigated.
• D. Once the permit is issued, re-entry may begin immediately.

Answer: (C)

Authorization to enter under a Re-Entry Permit happens only after confirming that all specified entry conditions are met and hazards are mitigated. The permit defines the controls needed—such as isolating energy sources, applying lockout/tagout, conducting atmospheric testing and continuous monitoring, ensuring appropriate PPE, establishing communication, and having rescue and emergency procedures ready. Merely having PPE on hand or doing a quick visual look does not guarantee the environment is safe, because conditions can change or still be unsafe even after a permit is issued. The entry should begin only after the supervisor has verified that every required condition is in place and effective, and then ongoing monitoring and controls must continue during entry.
