Which action is a typical first step in an effective post-incident investigation?

• A. Secure the scene
• B. Notify management
• C. File a standard report
• D. Increase surveillance

Answer: (A)

Securing the scene is the first step because preserving evidence and ensuring safety come before anything else. By establishing a controlled perimeter and preventing unauthorized access, you stop changes to the environment, prevent contamination of physical and digital traces, and create a reliable foundation for the investigation. Once the area is protected, you can document what happened, collect witness statements, and begin analysis with confidence. Notifying management and filing a standard report are important, but they come after the scene is secured to avoid compromising evidence. Increasing surveillance isn’t appropriate as a first action because it can alter the scene or raise privacy concerns and doesn’t address the immediate need to preserve evidence and safety.
