What is the correct action order when arriving at a shooting scene that has just been secured?

• A. Notify, then secure and isolate
• B. Secure, Isolate, and Notify
• C. Isolate, Notify, and Secure
• D. Secure only

Answer: (B)

The key idea is to protect people and preserve evidence by doing things in a logical safety-first sequence. When you arrive at a shooting scene, you first secure the area to remove or neutralize ongoing threats, establish your own safety as well as the safety of others, and set up a controlled space where responders can operate. This means ensuring there is no immediate danger and taking steps to control access if needed.

Next, you isolate the scene. This creates a defined perimeter that prevents unauthorized entry and helps preserve the integrity of evidence and the scene as it was at the time of the incident. By clearly marking inner and outer boundaries and documenting who comes and goes, you reduce the risk of contamination or disruption to investigations.

Finally, you notify the appropriate personnel. With the scene secured and isolated, you can relay accurate information to supervisors, investigators, and specialized units so they can respond with the right resources and plan. Timely and precise notification after safety and preservation measures ensures a coordinated and effective response.

If there are injured individuals, providing aid is important, but it should be done in a way that does not compromise securing and isolating the scene or delaying notification to the right units.
