In rope rescue, what is the purpose of a belay line?
Answer: To serve as a backup safety in case the main line fails
A belay line is a secondary safety system protecting against main-line failure.
What knot is commonly used to create a fixed loop at the end of a rescue rope?
Answer: Figure-eight on a bight
The figure-eight on a bight makes a strong, easily inspected fixed loop.
A typical static kernmantle life-safety rope used in rescue has what minimum diameter for general use?
Answer: 9.5 mm to 11 mm
General-use life-safety rope is typically around 11 mm (technical-use is thinner).
What is a mechanical advantage system primarily used for in rope rescue?
Answer: Multiplying hauling force to raise a load
A mechanical advantage (pulley) system multiplies force to haul heavy loads uphill.
What does the term 'two-tensioned rope system' (TTRS) describe?
Answer: Two ropes both sharing the load with no slack belay
TTRS uses two loaded ropes sharing the load instead of a separate slack belay.
When building an anchor, what principle helps ensure no single failure causes total collapse?
Answer: Redundancy
Redundancy provides backup anchor points so one failure doesn't cause total failure.
What is the maximum recommended angle between anchor legs to limit force multiplication?
Answer: Under 90 degrees
Keeping the internal angle under 90 degrees limits dangerous force multiplication on anchors.
