What additional feature should be present on a life safety rope?

A life safety rope should indeed possess high visibility color as an additional feature. This enhances safety during rescue operations, particularly in low-light or hazardous environments. A brightly colored rope can aid rescuers in quickly locating and identifying the rope during an emergency. Visibility can be especially crucial when time is of the essence, such as during nighttime operations or in situations where smoke or debris may impair visibility.

High visibility color helps distinguish the rope from its surroundings, improving the ability to track its position and monitor for any potential issues while the rope is in use. This feature aligns with the overall goals of technical rescue, which prioritize the safety and efficiency of both rescuers and victims during operations.

Other characteristics listed, such as low soaking capability, dynamic elongation, and durability against heat, are important in their own right and contribute to the overall performance of the rope, but they do not enhance the immediate visibility and identification of the rope under emergency conditions the way a high visibility color does.
