Which knot is preferred for tying two rescue ropes of equal diameter at the end?

• A. Square knot
• B. Bowline knot
• C. Figure 8 bend
• D. Clove hitch

Answer: (C)

The figure 8 bend is preferred for tying two rescue ropes of equal diameter at the end because it creates a secure, reliable connection that maintains the strength of both ropes. This knot is designed specifically for joining two ropes and is often used in climbing and rescue situations due to its ease of tying and untying, even after bearing load. When tied correctly, the figure 8 bend does not slip and provides a larger surface area in contact, which distributes the load evenly across both ropes. This is particularly important in rescue operations where the safety of individuals depends on the integrity of the knot under pressure. In contrast, while knots like the square knot might work for securing lighter materials, it is not as secure or reliable for joining rescue ropes and can slip under certain conditions. The bowline knot is excellent for creating a fixed loop but does not serve the purpose of connecting two separate ropes. The clove hitch is more suited for anchoring or tying to a post rather than joining two ropes together. This makes the figure 8 bend the optimal choice for the situation described.
