What is the minimum emergency equipment required on the dive site?

The minimum emergency equipment required on the dive site includes an Oxygen Tank, Emergency Action Plan (EAP), Backboard, First Aid supplies, and reliable Communication tools. This selection ensures that a comprehensive approach to medical emergencies is available.

An Oxygen Tank provides essential care for divers experiencing decompression sickness or other hypoxia-related issues. The Emergency Action Plan outlines procedures to follow in the event of an accident. A Backboard is crucial for safely transporting an injured diver, particularly if spinal injuries are suspected. First Aid supplies are indispensable for addressing minor injuries and stabilizing a diver until further help can be obtained. Communication tools are necessary for alerting emergency services and coordinating the response effectively.

Each of these components plays a vital role in managing potential dive emergencies, making option C the most comprehensive and appropriate answer.
