What is the first step in handling a stressed diver?

The first step in handling a stressed diver is to assess the situation for safety. This is crucial because ensuring the safety of both the diver in distress and the rescuer is paramount. Before taking any action, you must evaluate the environment, including potential hazards such as water conditions, depth, and the proximity of other divers.

An assessment helps to determine the best course of action without putting yourself or others at further risk. Effective rescue operations begin with a careful understanding of the circumstances, allowing for a more strategic and safe response. Once the situation is assessed and deemed safe, appropriate measures can be taken to assist the stressed diver, whether that be initiating a rescue or otherwise adapting the approach according to the circumstances.

The other options don't prioritize safety first, which is vital in emergency situations. Starting a rescue without assessing the environment could lead to further complications or danger. Changing the dive plan can be beneficial, but it should follow an initial safety assessment to gauge the diver's needs correctly. Ignoring the diver's behavior would not only fail to address the issue but could also exacerbate the situation, compromising everyone's safety. Therefore, conducting a thorough assessment is the foundational step in managing diver stress effectively.
