Rescue/Retrieval: What PPE requirement exists when working in enclosed spaces?

• A. Entrant and attendant are required to wear rescue harness when working in enclosed spaces.
• B. PPE is optional in enclosed spaces.
• C. Only entrant needs harness; attendant not required.
• D. Harness required only if asked by supervisor.

Answer: (A)

When you’re working in enclosed spaces, having a rescue/retrieval setup is essential for safety. A rescue harness is worn by both the person entering the space and the standby attendant. This allows a quick, controlled extraction if something goes wrong, with a retrieval line connected to an outside mechanism so the rescuer can aid without exposing themselves to the same hazards inside the space. Because a safe rescue depends on having a ready retrieval system, this PPE requirement is mandatory and not left to supervisor discretion or limited to just the entrant.
