Under NFPA 1500, if anything being supported by the rope is alive, the rope is designated as a Lifeline.

• A. Only for training
• B. False
• C. Only when used for rescue
• D. True

Answer: (D)

A line is treated as a lifeline when its purpose is to protect or rescue a person in a life-safety situation. If anything being supported by the rope is alive, the rope is performing a life-safety function, so it is designated a lifeline. This designation means the line must meet lifeline requirements for selection, use, inspection, and training, regardless of whether you’re using it for training, routine work, or actual rescue. The key idea is that the involvement of a living being being supported by the rope triggers lifeline status, not the context or purpose alone. Therefore, the statement is true.
