What action should be taken immediately if a bystander offers to help during a rescue?

The most effective action when a bystander offers to help during a rescue is to ensure they are capable and provide clear instructions. This approach is essential because it not only assesses the bystander's ability to assist effectively but also fosters a coordinated effort during the rescue.

By verifying that the bystander has the necessary skills or knowledge, a lifeguard can ensure that any help provided is both safe and effective. For instance, if the bystander is inexperienced in rescue techniques, they could inadvertently complicate the situation or even become a second victim. By giving clear instructions, the lifeguard can guide the bystander on how best to assist without compromising the safety of everyone involved. This collaborative approach can significantly enhance the chances of a successful rescue, ensuring that all involved are informed and prepared.

Other options do not promote safety or effective teamwork. For example, ignoring a bystander might mean missing out on valuable assistance, while allowing them to take charge could lead to disorder and confusion. Jumping directly into the water without briefing creates unnecessary risks, not only for the rescuer but also for the victim and the bystander. Thus, maintaining control of the situation through effective communication and assessment of the bystander’s capabilities is paramount.
