How much of the victim's body weight should a rescuer not exceed while performing a rescue?

During a rescue, the guideline that a rescuer should not exceed 70% of the victim's body weight is based on safety and effectiveness principles. This limit is crucial for ensuring that the rescuer maintains enough strength and stability to perform the rescue safely while also managing the victim's weight effectively in the water.

If the rescuer were to exceed this percentage, it could lead to inadequate control over the victim during the rescue, increasing the risk of both the rescuer and victim succumbing to exhaustion or panic. Staying within the 70% threshold allows for better maneuverability, reduces the risk of injury, and ensures that the rescuer can assist the victim back to safety without compromising their own safety. This guideline is part of standard practices in lifeguarding to ensure that rescues are conducted safely and effectively.
