Which characteristic of laid rope increases its risk of abrasion damage?

The characteristic of laid rope that increases its risk of abrasion damage is primarily related to its outer construction that allows fibers to surface. This construction results in exposed strands or fibers on the surface of the rope, which can easily come into contact with rough surfaces, leading to increased wear and damage. When the outer fibers are exposed and not tightly woven into the core of the rope, they are more vulnerable to abrasion from friction against edges, rocks, or other abrasive materials.

In contrast, options like the extensive use of synthetic fibers or the way fibers are interwoven does not significantly alter the tendency for abrasion damage in laid rope. While synthetic materials may be more durable than natural fibers, the construction of the rope is the key factor in this context. The weight of the rope also doesn't contribute to its susceptibility to abrasion; rather, it relates to handling characteristics rather than how easily the rope can be damaged by abrasion.

Thus, the outer construction that allows fibers to surface is a critical factor that elevates the risk of abrasion damage, making it an essential consideration in both the selection and maintenance of laid rope in rescue operations.
