What are the three phases of Search and Rescue (SAR)?

The three phases of Search and Rescue (SAR) are commonly understood to be linked to how the process is structured in responding to emergencies at sea. In this context, the phases begin with uncertainty, where a situation unfolds and the need for search and rescue might arise due to a lack of information about a person or vessel that is unaccounted for. This phase underscores the importance of gathering data and assessing the situation to determine if a search is warranted.

The next phase involves alert, wherein distress signals or reports of incidents are received. This phase is critical as it activates the response mechanisms, typically involving various agencies coordinating to respond to the emergency. This is where stakeholders like the Coast Guard mobilize to ensure that search efforts are initiated.

Lastly, the distress phase is reached when it's confirmed that a person or vessel is in danger. This phase encompasses the operational efforts directed towards finding and assisting those in peril.

In contrast, the other choice options don't accurately represent the comprehensive phases typically recognized in SAR operations. For example, while preparation and action are indeed vital components of emergency management, they do not encapsulate the complete SAR process. Similarly, terms like investigation and notification, or alert, report, and assist, while potentially relevant to some operational contexts, do not
