Why is it necessary to inform crew members of the "Security Level Declaration"?

Informing crew members of the "Security Level Declaration" is essential for enhancing their awareness and preparedness. When crew members are aware of the current security level, they can adjust their vigilance and responses accordingly, ensuring a heightened state of security awareness. This preparedness is crucial as it allows them to identify potential security threats, respond appropriately to incidents, and follow the necessary protocols relevant to the declared security level. These measures enhance the overall safety and security of the vessel and its operations.

While there are valid reasons for the other options, such as compliance with international laws or documentation for audits, the primary purpose of communicating the Security Level Declaration is to cultivate a proactive and informed crew that can effectively manage security risks.
