Which item helps facilitate rescue efforts in an aquatic facility?

An electrically insulated reaching pole is vital in facilitating rescue efforts in an aquatic facility because it is designed to extend the rescuer's reach while ensuring their safety from electrical hazards. This tool allows staff to assist individuals who may be in distress in the water without requiring them to enter the water themselves, which can be especially important in situations where the person in distress is in close proximity to electrical devices or equipment. Using a reaching pole effectively allows rescuers to provide assistance while minimizing risk to themselves, ensuring that rescue operations can be conducted safely and efficiently.

While other options, such as a deep water buoy and sound signaling devices, are useful in aquatic rescue scenarios, they serve different purposes. A deep water buoy is typically implemented to mark areas in the water or to provide flotation to individuals; a sound signaling device is valuable for alerting others to an emergency but does not directly assist in the physical act of rescue. A rescue helicopter, while crucial in large-scale water emergencies or for reaching individuals in remote areas, is not a practical tool for immediate rescue efforts within the confines of a typical aquatic facility.
