"Today emergency services, multiple-patient, and mass casualty incidents do and will occur. Emergency responders need to be able to manage these events effectively. A proven system, the Incident Command System (ICS), is designed to provide the emergency responder with an organization and system to manage these events effectively. There are many benefits to be gained from the use of the ICS. It enables the user to organize, control, and direct responders quickly. It eliminates the possibility of freelancing. It allows the Incident Commander (IC) to direct all responders toward a common goal. This organization, control, and direction minimize confusion and chaos. The ICS also provides for common terminology and position titles. It ensures that there is a communications plan and that radio communications to command team members are controlled. Proper radio designations for all command team members also is assured. The ICS creates a chain of command that ensures the proper flow of critical communications to the appropriate command team members. This information flow is vital; effective decisions cannot be made without proper and timely information. The ICS groups common functions and responsibilities within the organization. This assures that related functions are not fragmented and are not competing against one another. For example, all treatment-related functions are grouped under the Medical Group/Division Supervisor."
