What is the function of a backup line in a rope rescue operation?

• A. To wrap the casualty's leg in a protective sleeve.
• B. To decorate the rigging.
• C. To provide redundancy and back up the main line.
• D. To replace anchor entirely.

Answer: (C)

Redundancy and protection of the main rope are essential in rope rescue operations. A backup line runs alongside the main line to provide a second, independent path for control and safety. If the primary rope, anchor, or load path were to fail or shift, the backup line helps arrest movement, maintain control, and allow the operation to continue without dropping the casualty. It’s not used for decoration, not meant to wrap the casualty’s leg, and it does not replace the anchor; instead, it supplements the system to keep people safe even if something goes wrong with the main line.
