Which element must be attached to every entrant's harness?

• A. Flashlight
• B. Radio
• C. Lifeline
• D. Hard hat

Answer: (C)

Lifelines attached to every entrant's harness are essential for safe entry into hazardous or low-visibility environments. The lifeline provides a direct, controlled way for a rescuer outside the space to locate and retrieve the entrant or to assist them in exiting if conditions change or the entrant becomes incapacitated. By keeping the line attached and managed by a dedicated safety person or anchored to a fixed point, the team maintains accountability and a clear path to safety, even when you can’t rely on sight or voice alone. While a flashlight, radio, or hard hat are important tools for protection and communication, they do not guarantee rapid rescue or location in a dangerous space, which is why the lifeline is the required attachment.
