Which statement is least aligned with standard confined space entry requirements?

• A. Wearing a full body harness
• B. Using SCBA or SAR for air supply
• C. Lifeline attached
• D. Not requiring a safety plan

Answer: (D)

A safety plan is essential for permit-required confined space entries because it lays out how hazards will be identified, controlled, and managed, who is involved, how monitoring and communication will be maintained, and how rescue will be handled if something goes wrong. Without it, there’s no written, approved approach to protecting workers in the space.

Wearing a full body harness is part of a retrieval system, enabling a safe rescue or retrieval of the entrant. A lifeline attached to the entrant is similarly a key part of monitoring and recovering someone inside the space. Using a supplied-air respirator or SCBA is required when the atmosphere inside the space could be toxic or have insufficient oxygen, ensuring the entrant has breathable air. Each of these elements supports safe entry and rescue operations.

In contrast, not requiring a safety plan misses a fundamental element of safe confined space operations. The plan coordinates the permit process, hazard controls, atmospheric testing requirements, ventilation, standby/rescue arrangements, communication, and roles, making it a baseline requirement for entry.
