Characteristics of a Type 3 Incident are as follows:

• Resources: When capabilities exceed initial response, the appropriate ICS positions should be added to match the complexity of the incident. Some or all of the Command and General Staff positions may be activated, as well as Division or Group Supervisor and/or Unit Leader level positions. An Incident Management Team (IMT) or incident command organization manages initial action incidents with a significant number of resources, and an extended response incident until containment/control is achieved.
• Time Span: The incident may extend into multiple operational periods and a written Incident Action Plan may be required for each operational period.
