What is the first consideration when handling any 400-series call on arrival?

• A. Scene safety for officers, bystanders, and suspects.
• B. Determining the suspect's identity.
• C. Transporting suspects to the station.
• D. Recording weather conditions.

Answer: (A)

Scene safety for officers, bystanders, and suspects is the first thing you address on arrival. When you step into a 400-series scene, your top priority is to identify and control immediate hazards—such as weapons, unstable crowds, traffic, or other dangers—and secure the area so everyone remains safe and the investigation can proceed. Only after the scene is stabilized should you move on to other tasks like identifying involved individuals, transporting suspects, or collecting situational details like weather, which are important but come after safety and scene control.
