What installation requirement ensures belay cable safety?

• A. Must have a full-strength backup component or system in place
• B. Must be attached to a tree with rope
• C. No backup needed
• D. Use nylon rope for belay

Answer: (A)

Redundancy in a belay setup is essential. Having a full-strength backup component or system means there’s a second line or independent anchor that can arrest a fall if the primary line or anchor fails. This backup protects against a single point of failure and keeps the belay cable safe by ensuring there’s a fail-safe that can take loads if anything goes wrong with the main system. The other ideas don’t provide that guaranteed safety: attaching to a tree with rope doesn’t ensure the anchor’s strength or provide redundancy; no backup eliminates the safety net; and simply choosing nylon rope for belay doesn’t address the critical need for an independent, strong backup in the installation.
