Rescue harness: who must wear?

• A. PPE is optional.
• B. Only entrant.
• C. Only attendant.
• D. Entrant and attendant are required to wear rescue harness when working in enclosed spaces.

Answer: (D)

When people work in enclosed spaces, there’s a need for a quick and controlled way to pull someone out if something goes wrong. A rescue harness provides a secure attachment point to a retrieval line, making that rescue possible without unnecessary struggle or delay. Because conditions can change and a rescuer or the entrant may need assistance, both the person entering the space and the person outside monitoring must wear a rescue harness. The entrant’s harness is linked to the retrieval line so responders can haul them out efficiently, while the attendant carries or is connected to the same rescue setup to stay protected and ready to assist or be retrieved if needed. PPE isn’t optional in these scenarios, and limiting harness use to only one role would leave someone unprotected and hinder rescue operations.
