What is one disadvantage of a direct haul system?

The correct answer highlights a specific challenge associated with a direct haul system, particularly in environments such as rocky terrains or glacial areas. In a direct haul system, the load is lifted directly upward using a pulley system with little deviation from the vertical path. This can lead to the rope becoming trapped or "entrenched" in crevasse lips during rescue operations. When the rope gets stuck, it can hinder progress, complicate the rescue, and potentially put both the rescuer and the victim at risk.

Understanding this disadvantage is crucial for rescuers, as they must be aware of the environment and how specific systems will perform under those conditions. This knowledge helps them make informed decisions in planning and executing their rescue operations effectively, prioritizing safety and efficiency.
