What are the two types of rope used in life-safety situations?

In life-safety situations, the two types of rope that are predominantly used are dynamic rope and static rope.

Dynamic rope is designed to stretch under load, which allows it to absorb the shock of a fall. This elasticity makes it particularly suitable for climbing and other operations where sudden loads can occur, as it reduces the impact forces on the climber and the anchor points. Therefore, when safety is a priority, the ability of a rope to extend and absorb energy is critical, and dynamic ropes are specifically engineered for these scenarios.

Static rope, on the other hand, is designed with minimal stretch, making it ideal for applications where safety and stability are paramount, such as rappelling, rope rescue, and securing items. The low elasticity ensures that the rope does not stretch significantly under load, allowing for more precise control and stability when moving or securing personnel and equipment.

Other types of ropes mentioned in the other choices, such as utility and kernmantle, serve different purposes that may not be focused on life safety. Utility ropes are more versatile and can be used for various tasks, but are not specifically designed for life-safety situations. Kernmantle refers to the construction method used in certain ropes where the core provides strength and the outer sheath protects it
