Which of the following is a listed benefit of polyester slings?

• A. economical
• B. heavy weight
• C. needs frequent replacement
• D. magnetic properties

Answer: (A)

Polyester slings are economical, which is why this is the listed benefit. They cost less upfront than metal slings and, with proper use and inspection, offer a favorable life-cycle cost. They’re also lightweight and easy to handle, but the key point tied to the question is the affordable purchase and overall lower cost. The other options describe traits that aren’t benefits: they’re not heavy (they’re actually lightweight), they don’t inherently require frequent replacement, and magnetic properties aren’t a typical advantage of polyester slings.
