What should a rescuer evaluate about the litter or patient if the mainline operator releases the DCD?

When a mainline operator releases the descent control device (DCD), it is crucial for the rescuer to assess the situation regarding the litter or patient because the system’s stability is compromised. In this scenario, the most significant concern is that the load—including the litter and patient—will begin to swing freely without control. When the DCD is released, the tension in the rope is lost, and there are no mechanisms in place to manage or stabilize the load; as a result, it may begin to move in an uncontrolled manner.

This uncontrolled swing can pose a risk to both the patient and the rescue personnel, as it may lead to collisions with environmental hazards or create further complications needing additional rescue operations. Therefore, understanding that the load will swing freely emphasizes the necessity for rescuers to be vigilant and prepared to react quickly to prevent accidents and ensure safety during the operation.
