How should the litter be connected to the mainline ropes?

The most effective method for connecting the litter to the mainline ropes is through an interwoven or double long tail bowline knot. This knot is preferred in rope rescue scenarios because it creates a secure loop that is strong and reliable, while also being relatively easy to untie after use, even after heavy loading.

The interwoven or double long tail bowline provides a stable connection point that distributes the load evenly, minimizing the risk of slippage or failure during rescue operations. It allows for easy attachment and detachment from the litter, which is crucial in emergencies when time is of the essence.

Furthermore, the design of the long tail bowline allows for sufficient strength, making it ideal for suspending loads such as litters carrying victims. Its structure also avoids the risk of unintentional disconnection under dynamic loads, which can occur during rigging or when moving the litter.

Utilizing a simpler knot, such as a square knot or clove hitch, may not provide the same level of security or load distribution that is necessary in rescue operations, making them less suitable for this critical application.
