Which knot is commonly used for securing safety lines in a low-angle operation?

The Figure Eight knot is commonly used for securing safety lines in low-angle operations due to its reliability and security. This knot provides a strong connection that can withstand significant loads, making it suitable for rescue scenarios where safety is paramount. Its structure allows for easy tying and untieing, even after being subjected to a load, which is essential in emergency situations.

Additionally, the Figure Eight knot creates a closed loop, which can be easily used for connecting to harnesses, anchor points, or other gear. This characteristic is critical in low-angle operations, where quick and secure attachment is necessary. The knot’s design also minimizes the risk of slippage, ensuring that the safety line remains securely in place during the operation, thus enhancing the overall safety of the rescuers and victims involved.
