What is required for a diver to assist another diver in distress?

To assist another diver in distress effectively, a calm assessment of the situation followed by physical assistance is essential. This approach ensures that the rescuer can evaluate the severity of the distress and make informed decisions about how to provide appropriate help. A thorough assessment allows the diver to identify any immediate hazards, such as entanglements or rapid ascents, and understand the needs of the distressed diver.

In contrast, rushing to the rescue without assessing the situation can lead to further complications, potentially endangering both divers. Communication is vital in a rescue scenario, and using underwater signals effectively helps in coordinating the rescue effort rather than relying solely on physical actions. Moreover, waiting for help from instructors without making an initial assessment might delay necessary assistance and could worsen the situation for the diver in distress. Therefore, the best practice involves a calm evaluation followed by appropriate actions, making the first response as safe and effective as possible.
