Which phase involves the identification of vessel hazards and safety checks?

The phase that involves the identification of vessel hazards and conducting safety checks is indeed the initial phase of a boarding operation. This stage, known as the Law Enforcement Phase 1, focuses on gathering pertinent information about the vessel and assessing any potential risks associated with it. This includes evaluating the vessel's condition, crew behavior, and other factors that may pose safety concerns. By thoroughly identifying hazards in this first phase, officers can develop an effective strategy for proceeding with the boarding while ensuring the safety of both the boarding team and the individuals on the vessel. This foundational step is crucial in establishing situational awareness and maintaining operational safety as the boarding operation progresses.
