Shore-based rope rescue is a crucial technique used in swiftwater rescue operations, where rescuers work from the shore to assist victims caught in fast-moving water. This type of rescue avoids direct swimming or wading into the current, focusing instead on utilizing ropes and lines to secure and stabilize the victim from a safe distance. It includes a variety of methods such as stabilization lines, snag lines, and inverted paddle snag lines, each designed to handle different rescue scenarios effectively.

Stabilization Line: A Critical Lifeline in Swiftwater Rescue

The stabilization line plays a vital role in supporting the victim by allowing them to hold onto the line with their arms or hands. This line helps the victim keep their head above water, ensuring they can breathe until further rescue steps can be taken. It is particularly important in fast-moving currents, where any lapse in maintaining a secure position can be dangerous.

One of the key challenges with the stabilization line is the load placed on the belayer—the person managing the line from shore. As the situation persists, fatigue can build up due to the constant strain of holding the line. To mitigate this, a hip belay technique is often recommended. This method helps distribute the load more evenly across the body, reducing fatigue and increasing endurance.

The 120-degree rule is another important factor to consider. This rule states that if the angle between two belayers is 120 degrees, the force exerted on both the victim and the belayers is equal. For example, if the victim is subjected to a 50-kilogram force, the belayers will also experience a 50-kilogram load. This balance is critical to avoid overloading any one party. Although this perfect angle is not always feasible, minimizing the angle can help reduce the strain on the belayers. Additionally, a backup belayer can further stabilize the situation by securing the belayer from behind, ensuring they do not lose footing or slip off the rocks.

In terms of safety, it is crucial to have both upstream and downstream safety teams in place. Upstream safety helps prevent other individuals from being swept into the rescue area, while downstream safety is essential for two reasons: rescuing any rescuers who may fall into the water and retrieving victims who were not secured upstream. These safety measures are vital to maintaining control over the situation, ensuring all parties involved are protected.

Snag Line: Overcoming Obstacles in Swiftwater Rescue

The snag line is another essential tool in shore-based rope rescue, designed to assist victims who are trapped by obstacles like rocks or branches in the water. The snag line is positioned lower in the water to help free the victim from these hazards. This method often works in tandem with the stabilization line to secure the victim while releasing them from entrapment.

To deploy a snag line, rescuers on opposite banks of the river must coordinate. For example, one rescuer on the right bank throws the line to a rescuer on the left bank. The rescuer on the left bank then secures the line using carabiners and fills throw bags with rocks to weigh the line down in the water. The rescuers then work together, gradually pulling the line upstream until they can free the victim from the obstacle.

The 120-degree rule comes into play here as well. The farther upstream the rescuers move, the less force is needed to pull the victim free. However, it’s important to ensure that when the snag line crosses the stabilization line, it does so beneath it. This prevents the snag line from interfering with the stabilization of the victim, allowing for a smoother rescue process.

Inverted Paddle Snag Line: A Tactical Approach to Overcoming Currents

In situations where the current makes it difficult to position the snag line correctly, the inverted paddle snag line technique offers a solution. This method involves using the shaft of a paddle to lower the snag line below the victim. One of the primary challenges with the standard snag line is that even when weighted with rocks, the current may push the line above the victim, making it difficult to position correctly.

By using a paddle, rescuers can guide the snag line more effectively, ensuring it reaches the right position to free the victim. This approach is particularly useful in scenarios where the current is too strong for conventional snag line deployment.

Cinches: Securing the Victim with Precision

Cinches are techniques used to secure the victim tightly with a rope during a swiftwater rescue. There are several types of cinches, each designed for different situations. The simple cinch is a basic method that can be easily adapted from a stabilization line, offering a straightforward yet effective way to secure a victim.

Simple Cinch: Step-by-Step

1. Throw the Rope: Begin by stretching the stabilization line across the river. The rescuer on one bank throws a throw bag to the rescuer on the opposite bank.
2. Clip In: The rescuer on the receiving side clips the throw bag line to the stabilization line.
3. Perform the Cinch: The belayer pulls the rope downstream and under the stabilization line, then pulls diagonally to secure the victim.
4. Swing to Shore: The belayer pulls the victim toward the shore while the other belayer maintains tension and slackens the line as needed.

KUI Cinch: For Shoreline Victims

The KUI cinch is used when the victim is close to the shore. Rescuers throw the rope simultaneously from both banks, creating a cinch around the victim. This method requires careful coordination, and the key move is the over-and-under technique, where one rescuer passes over the other’s line, forming a tight cinch.

Carlson Cinch: For High-Risk Situations

The Carlson cinch is a more advanced technique used in life-threatening situations or body recovery. Once tightened, it is not easily released, which can cause internal injuries if used improperly. This method is generally reserved for situations where the victim’s condition is critical or in the case of recovering a body.

In all cinch methods, proper technique and coordination are crucial to ensure the victim’s safety. While the simple cinch and KUI cinch are more flexible, the Carlson cinch should only be used when absolutely necessary, due to the risks involved.

Conclusion

Shore-based rope rescue is an essential skill in swiftwater rescue operations, offering a safe and effective way to assist victims without directly entering the water. Techniques such as the stabilization line, snag line, and cinches provide rescuers with the tools they need to perform these operations efficiently. However, each method requires careful attention to detail, from maintaining the correct angles to coordinating movements with other rescuers.

Understanding these techniques not only increases the chances of a successful rescue but also ensures the safety of both the victim and the rescuers involved. While these methods are effective, they require practice and precision, making training and preparation key components of any swiftwater rescue operation.
