Core Concepts and Principles Flashcards

What is the primary purpose of a rebelay in a rope access system?

Answer: To create an intermediate anchor that redirects the rope away from hazards or edges

A rebelay re-anchors the rope partway down to avoid abrasion points or reposition the line.

How does a deviation differ from a rebelay?

Answer: A deviation pulls the rope sideways to change its path without the rope being re-tied to an anchor

A deviation uses a sling and connector to redirect the rope's path rather than re-anchoring it.

As the angle between the two legs of a Y-hang anchor increases toward 120 degrees, what happens to the load on each anchor?

Answer: It increases until each leg carries about 100% of the load

At 120 degrees each leg bears roughly the full load, so wide angles should be avoided.

Which practice best protects ropes where they pass over a sharp building parapet?

Answer: Installing edge protection such as rope protectors or edge rollers

Edge protection prevents cutting and abrasion of the rope at contact points.

What feature should a descender used on the working line have according to rope access best practice?

Answer: An auto-locking or hands-free stop function

Auto-locking descenders stop the technician if they lose control or let go.

After a rope has been subjected to a significant shock load, what is the correct action?

Answer: Remove it from service and follow the manufacturer's retirement guidance

Shock-loaded ropes may have hidden core damage and should be retired per manufacturer guidance.

Why should a drop zone or exclusion zone be established below rope access work?

Answer: To protect people below from falling tools and debris

Barricaded exclusion zones keep the public and coworkers clear of dropped-object hazards.
