What technique helps to minimize fatigue while working over the edge during a litter operation?

Leaning back and away from the cliff during a litter operation is an effective technique for minimizing fatigue. This position allows the individual to use gravity to their advantage while managing the weight of the litter and the patient. By shifting their weight away from the edge, a rescuer can create a more stable and comfortable posture, which reduces the strain on their muscles and allows for longer periods of operation without excessive fatigue.

In a rescue scenario, especially on steep or rugged terrain, maintaining a balanced and ergonomic posture is crucial. Leaning back decreases the physical demand on the arms and shoulders, enabling the rescuer to better conserve energy while ensuring safety during the operation.
