What procedures should be followed when dealing with an active shooter incident as outlined in SOP202?

Establishing perimeter security and coordinating with law enforcement is critical during an active shooter incident, as outlined in SOP202. This action is vital for ensuring the safety of individuals inside the premises, as well as those outside. By creating a secure perimeter, responders can manage the scene effectively, control access, and prevent further infiltration by the shooter.

Additionally, coordination with law enforcement helps in the rapid deployment of tactical teams and medical assistance to the scene. This collaboration ensures that trained professionals can handle the complexities of the situation, allowing for a more effective response that prioritizes the safety of both civilians and first responders.

While other options may seem appropriate in certain contexts, they do not encompass the comprehensive, organized approach required in a scenario involving an active shooter. Establishing a secure boundary and working closely with law enforcement forms the backbone of a structured response plan, ultimately leading to better outcomes in such critical situations.
