Which statement about SPRAT ropes is true?

Which statement about SPRAT ropes is true?

• A. They are made from natural fibers and have high strength.
• B. They are made from synthetic fibers such as nylon, polyester, or aramid, with a minimum breaking strength of 22.2 kN.
• C. They are always used as dynamic ropes with high stretch.
• D. They have no specified minimum breaking strength.

Answer: (B)

Spring from the idea that rope access gear uses reliable, modern materials with clear strength specs. SPRAT ropes are designed as synthetic kernmantle ropes, typically made from nylon, polyester, or aramid. These materials provide predictable strength, resistance to moisture, and good durability in harsh work environments. A defined minimum breaking strength is required to establish a safe operating margin, and for SPRAT ropes that value is 22.2 kN. Natural fiber ropes—like sisal or manila—don’t meet these standards because they absorb water, degrade more quickly, and have inconsistent strength, making them unsuitable for SPRAT work. The statement about always using dynamic ropes with high stretch isn’t accurate for rope access, where static or low-stretch ropes are often preferred for work positioning and rescue. And there is, in fact, a specified minimum breaking strength; saying there isn’t would be false.
