The established protocol for a person unexpectedly entering the water from a vessel involves immediate and decisive actions. These actions are designed to maximize the chances of a successful rescue and minimize risk to both the person in the water and the crew on board. These actions are a matter of survival.
Following a specific procedure is crucial because time is of the essence. Hypothermia, exhaustion, and disorientation can rapidly affect a person in the water, particularly in adverse weather conditions. Furthermore, swift action preserves vital evidence, such as the initial location of the incident, which aids in the recovery process.
