What purpose do festoons serve in a high line system?

Festoons in a high line system play a crucial role in managing the tag lines effectively. By maintaining a certain configuration of the tag lines, festoons help prevent them from sagging, which can cause difficulties during operation and create potential hazards. Properly arranged festoons ensure that tag lines have the necessary tension and that they remain accessible and functional throughout the rescue process. This management is vital for maintaining safety and efficiency, as sagging lines can lead to complications in maneuvering loads or can contribute to entanglement during a rescue operation.
