Which option lists the valid anchor point to secure a tieback or lifeline?

• A. Water Tank
• B. Dunage
• C. Concrete Wall
• D. Water Tank Dunage

Answer: (D)

The key idea is choosing an anchor point that is fixed, solid, and capable of taking the load without shifting or failing. When securing a tieback or lifeline, you want a surface that can distribute the load and not damage the structure you’re attaching to. Water Tank Dunage is the best choice here because it uses the water tank as a stable support and employs dunage (load-distributing padding) to spread the load and protect the tank surface. This setup helps create a reliable, rated anchor point while reducing the risk of crushing or slipping, which can happen if you attach directly to a smooth or unsupported surface. The other options either describe non-anchoring items (dunage alone), a surface that may not be a proper anchor by itself (water tank), or a different structural option (concrete wall) that isn’t specified as the prepared, rated anchor in this context.
