Which knot is frequently used for rescue operations due to its strength and versatility?

The Figure-8 knot is favored in rescue operations primarily because of its strength, reliability, and ease of use. This knot forms a secure loop that can handle heavy loads and is less likely to slip or come undone compared to other knots when properly tied. Its design allows for high visibility and easy identification, which is crucial in emergency situations where time and clarity are essential.

Additionally, the Figure-8 knot is versatile and can be used in various applications within rope rescue scenarios, such as creating a harness or securing a rope to a harness. It can also be easily untied after loading, unlike some other knots that may be difficult to release after use.

This knot plays a central role in many systems utilized in rope rescue due to those qualities, making it a go-to choice for professionals in the field.
