Core Concepts and Principles Flashcards

Which knot is commonly used to create a secure end-of-line loop for anchoring in rope access?

Answer: Figure-eight on a bight

The figure-eight on a bight is strong, easy to inspect, and widely used for anchor loops.

Why do knots reduce the effective strength of a rope?

Answer: Tight bends concentrate stress on fibers at the curve

Sharp bends in a knot unevenly load fibers, reducing rope strength by roughly 20-35%.

What is the purpose of a stopper knot at the end of a working line?

Answer: To prevent the technician from descending off the end of the rope

An end knot stops the descender from running off the rope end.

What type of connector should be used for life-safety connections in rope access?

Answer: Self-locking or screw-locking carabiner rated for life safety

Locking carabiners rated for life safety prevent accidental gate opening.

What is the main purpose of the shock-absorbing lanyard often used between the back-up device and harness?

Answer: To limit impact forces on the body and anchors during a fall arrest

Energy absorbers reduce peak arrest force on the technician and the system.

When should ropes and equipment be inspected in a SPRAT system?

Answer: Before each use, plus periodic documented detailed inspections

Pre-use checks by the user and periodic documented inspections by a competent person are both required.

Which situation best describes work positioning, as opposed to fall arrest?

Answer: The technician is supported in position by the rope system while working

Work positioning holds the worker in place under tension, while fall arrest stops a fall that has already started.
