Where will the investigator focus their investigation primarily?

The primary focus of the investigator's examination will be around the casualty, as this area is crucial for understanding the context and circumstances surrounding the incident. By concentrating on the location where the casualty occurred, the investigator can gather vital evidence, witness accounts, and physical clues that may explain how the event transpired. This includes assessing any potential hazards, examining any equipment that may have been involved, and looking for environmental factors that could have contributed to the situation.

While other areas, such as the control room or engine room, may provide relevant information about operational conditions or processes, they are secondary to the immediate vicinity of the casualty. The deck area may also hold some significance, but it is often more related to the location of operations than the specifics of the casualty itself. Focusing on the area around the casualty helps to establish a detailed narrative of the incident, which is essential for effective investigation and analysis.
