What should a security guard do after responding to an incident?

After responding to an incident, it is essential for a security guard to complete all necessary reports and notify their supervisor. This process is crucial because it ensures that all details of the incident are documented accurately, which can be helpful for future reference or for any investigations that may arise. Proper documentation serves as an official record that outlines what occurred, including any actions taken by the security guard, and can help in evaluating the effectiveness of the response and in making decisions for future incidents.

Additionally, notifying a supervisor is important because it allows for the proper escalation of the incident within the organization, ensuring that the management is informed and can take necessary follow-up actions. This step is a critical part of the security guard's responsibilities and helps reinforce accountability within the security team.

While other options may involve actions that could be necessary under certain circumstances, the primary responsibility after addressing an incident effectively centers around reporting and communication.
