What is the first thing an officer should do upon arriving at a scene?

The first thing an officer should do upon arriving at a scene is to assess the scene for safety. This step is crucial because ensuring one's own safety and the safety of others present is the primary concern in any situation. By evaluating the environment, the officer can identify potential hazards, such as ongoing threats, unstable structures, or hazardous materials, and take appropriate measures to protect themselves and others.

Safety assessments allow the officer to make informed decisions about subsequent actions, such as whether to engage with potential suspects or aid victims. It establishes a secure perimeter and informs any needed deployments of additional resources, such as medical assistance or backup units, ensuring that the response is effective and coordinated.

Following safety assessments, officers can then proceed to engage with witnesses, collect evidence, or call for backup if necessary, but the initial priority must always be to confirm that the scene is safe for them and any civilians involved.
