What should a guard do if they observe a potential security breach?

When a guard observes a potential security breach, the most appropriate action is to immediately report it to the supervisor. This course of action ensures that the situation is handled by someone with the authority and experience to manage security incidents. Prompt reporting can lead to quick assessment and response, potentially preventing further issues or escalation of the breach.

Alerting a supervisor allows for coordinated response efforts, which may involve additional personnel or law enforcement if necessary. It also ensures that the situation is documented and managed according to established security protocols, which are crucial for maintaining safety and accountability.

Taking immediate action is essential in security roles, as even small breaches can lead to larger threats if left unaddressed.
