Which type of rope is not recommended for rescue according to the material?

• A. Synthetic fiber ropes
• B. Nylon ropes
• C. Polyester ropes
• D. Natural fiber ropes

Answer: (D)

Rope choice in rescue matters because how a rope behaves under load, moisture, and edge wear determines safety and reliability. Natural fiber ropes—like manila or cotton—don’t hold up well in real-world rescue conditions. They soak up water, and when wet they lose a lot of strength, become heavier and harder to handle, and deteriorate faster through rot and mildew. They also tend to have poorer abrasion resistance and less predictable performance, making them more prone to damage or failure when loaded or dragged over rough edges. Because of these weaknesses, natural fibers are not trusted for critical rescue work. In contrast, synthetic ropes are designed to maintain strength when wet, offer more consistent performance, and resist environmental damage, which is why they’re preferred in rescue scenarios.
