When should a rope not be tensioned at right angles to the current during in-water operations?

Tensioning a rope at right angles to the current can create several hazards, which is why it should generally be avoided during in-water operations. When the rope is tensioned perpendicular to the current, it can pull rescuers into the main flow of water, increasing the risk of being swept away or overpowered by the current.

In addition, when operating under such conditions, the dynamic forces exerted on the rope can lead to sudden and unpredictable movements, which may compromise the safety and control of both the rope and the personnel involved. It can also lead to scenarios where a victim or a rescuer becomes inadvertently entrapped in the current due to the line's position.

Gathering all these considerations, it's evident that maintaining a safe angle for tensioning the rope is crucial, especially in moving water rescue operations. Therefore, the assertion that a rope should not be tensioned at right angles to the current during in-water operations reflects sound safety practices in swiftwater rescue scenarios.
