The Vashon EOC and Vashon Fire operates according to the nationally approved National Incident Management System. First responders (Vashon Fire) follow the Incident Management System (ICS). The Vashon EOC has a unqiue model aligned with both the ICS and Incident Support Model (ISM).
The National Incident Management System (NIMS) is a systematic, proactive approach to guide departments and agencies at all levels of government, nongovernmental organizations, and the private sector to work together seamlessly and manage incidents involving all threats and hazards—regardless of cause, size, location, or complexity—in order to reduce loss of life, property and harm to the environment.
The Incident Command System (ICS) is a command and communication system for emergencies and events. It establishes a process and communication system to improve effectiveness, particularly when dealing with multiple agencies. Although the system is in a constant state of refinement, it has successfully streamlined a variety of tasks that have been adopted by many agencies and international organizations in order to respond to emergencies.
The Incident Support Model (ISM), unlike the more traditional ICS, Emergency Support Function (ESF), or Departmental models historically followed by other EOCs, focus on what our EOC does - supporting those in the field - and thus better matches our organizational structure to our mission. As stated by the 2017 NIMS Refresh document, this model puts the EOC manager in direct contact with those doing situational awareness/information management, and streamlines resource sourcing, ordering, and tracking.
