What is a way to avoid heat fusion?

To avoid heat fusion in rescue scenarios, rigging ropes so that they do not make contact is an effective strategy. Heat fusion occurs when ropes are subjected to excessive friction, leading to heat buildup that can weaken or damage the fibers of the rope. By ensuring that ropes are separated and do not rub against each other or any other surfaces, you minimize the risk of friction and heat-related damage. This method helps maintain the integrity and strength of the ropes during a rescue operation, ensuring they perform as intended and keeping the safety of the rescue team paramount.

While other options might involve the positioning and use of ropes, they do not directly address the need to prevent contact, which is essential for avoiding heat fusion.
