What should a security guard do in preparation for patrols?

Reviewing previous incident reports is crucial for a security guard's preparation for patrols as it provides insight into any patterns or recurring issues that may need attention. By understanding past incidents, a guard can be more vigilant in areas that have previously experienced problems, thereby enhancing their situational awareness and response capabilities. This knowledge helps in anticipating potential security threats and allows the guard to develop appropriate strategies to mitigate risks during their patrols.

The other choices, while they may have their merits in different contexts, do not directly contribute to the immediate effectiveness of a security guard's patrol duties. Calculating potential profit for a property does not pertain to the security guard's primary responsibilities and focuses on business aspects rather than safety. Engaging in team-building exercises is beneficial for overall team dynamics but is not typically a preparatory action immediately before patrols. Focusing solely on personal goals detracts from the collaborative and vigilant nature required in security roles, where the primary objective is to ensure the safety and security of the premises and the people within them.
