3 Echo Concept of Operations for Early Care and Evacuation of Victims of Mass Violence

The authors describe a three-phase approach to mass violence incidents used by their metro area and applied by responders during a mass shooting event in 2012: Enter, Evaluate, and Evacuate (or 3 Echo). 3 Echo stresses the same principles of the ‘rescue task force’ concept - early, multi-disciplinary coordination and teaches participants about unified command, swift victim evacuation, how to establish corridors of safety, and other critical skills.
