In case of a hull breach, what is the first action to take?

In the event of a hull breach, the immediate priority is to identify the source of the breach and contain the flooding. This action is crucial because it allows for a quick assessment of the situation and enables the crew to take necessary measures to stop or reduce water ingress. By identifying where the water is coming in, effective containment strategies can be implemented, such as using pumps, sealing off compartments, or deploying flooding control methods.

Addressing the breach and containing the flooding is essential to maintaining the integrity of the vessel and ensuring the safety of all onboard. This proactive approach helps to prevent further damage and potential capsize, which could result from uncontrolled flooding. While calling for an emergency rescue, evacuating crew members, or assessing damage are all important steps in emergency protocol, they become effective only after immediate containment efforts have been initiated.
