What prompted the shift from natural fiber rope to synthetic rope?

The transition from natural fiber rope to synthetic rope primarily stemmed from fiber degradation issues associated with natural fibers. Natural fibers, such as manila or sisal, are susceptible to environmental factors including moisture, UV light, and biological degradation. This vulnerability can lead to significant loss of strength and safety, especially in demanding conditions typical of rescue operations.

Synthetic ropes, made from materials like nylon or polyester, are designed to resist these degradation factors, offering a longer lifespan and greater durability under varying environmental conditions. This shift ensures that rescue personnel can rely on equipment that maintains its integrity and strength over time, enhancing safety and performance in rescue scenarios.

While improved manufacturing technology, cost-effectiveness, and advancements in rescue techniques are all important factors in the evolution of equipment and methods, the immediate impetus for switching to synthetic ropes was the inherent limitations and safety risks posed by natural fiber degradation.
