In the event of a self-rescue, what should be the immediate action taken?

The immediate action to take during a self-rescue is to attach the snaphook to an anchor point. This step is critical because it secures the individual to a reliable support, preventing further fall or injury while additional actions are taken to ensure safety. By anchoring oneself, a person can stabilize their position and begin the process of evaluating their situation or calling for assistance without the risk of falling or being in a precarious state.

Securing to an anchor point serves as a foundational step in the self-rescue process, allowing for safe maneuvering and the ability to strategize the next steps effectively. It ensures that, even if the situation feels precarious, there is a safety measure in place that can help prevent exacerbating the emergency. Each of the other choices, while important in the overall context of safety, are not the immediate priorities when looking to secure oneself and gain a stable footing in a self-rescue situation.
