What is the first action when responding to a crime scene?

• A. Determine if the area is safe by visually scanning, listening for hazards, and using other senses.
• B. Enter quickly to assess the extent of the scene.
• C. Call for backup before evaluating safety.
• D. Begin securing the perimeter immediately.

Answer: (A)

The immediate priority is scene safety established through a rapid size-up. You determine if the area is safe by visually scanning, listening for hazards, and using your other senses. This quick check reveals immediate dangers—like weapons, hazardous materials, unstable structures, or environmental risks—and guides how you enter, what PPE you need, and whether additional help is required. Entering quickly to assess extent or securing the perimeter without first confirming safety can expose you and others to harm and may disturb evidence. Perimeter security matters, but it should follow a safety assessment so responders can operate without unknowingly stepping into danger. In short, assess safety first, then plan the rest of the response.
