3. ASIM Checklist

This video gives a fast, plain-language overview of the ASIM (Active Shooter Incident Management) Checklist from the National Center for Integrated Emergency Response. Validated over more than a decade and endorsed by the National Tactical Officers Association, the checklist organizes an active shooter response around three priorities: active threat, rescue, then clear. The presenter walks through the six-panel, two-sided format, showing how duties are assigned by arrival order (from the first officer on scene through supervisors and fire/EMS) and where to find task-specific guidance for contact teams, rescue task forces, and more. The video explains how ASIM standardizes roles, communication, and decision-making across law enforcement, fire, EMS, and other disciplines so actions happen in the right order, time is saved, and lives are more likely to be preserved.
