Two types of rope used in life-safety situations are:

• A. Dynamic and static rope.
• B. Utility and kernmantle rope.
• C. Dynamic and utility rope.
• D. Twisted and braided rope.

Answer: (A)

Ropes used in life-safety situations are judged by how much they stretch under load. Dynamic rope is designed to elongate when a load is applied, absorbing the energy of a fall and reducing the peak forces on the person or system. Static rope has very little stretch, providing predictable length and greater control for tasks like hauling, lowering, or rigging in a rescue. Because of these distinct behaviors, the two types commonly associated with life-safety use are dynamic rope and static rope. Other pairings mix construction or general-purpose rope types that don’t address how the rope behaves under load, which is the key factor in selecting rope for safety-critical work.
