Which incident type is characterized by activation of command and general staff, extended operational periods, and a written IAP?

The incident type characterized by the activation of command and general staff, extended operational periods, and a written Incident Action Plan (IAP) is Type 2. This type of incident typically requires a coordinated response from multiple agencies and involves more complex operations than lower types due to the scale and scope of the incident.

Type 2 incidents involve extended operational periods where planning and resource management are crucial, leading to the necessity of having a formal IAP. This ensures that all team members are on the same page regarding objectives, strategies, assignments, and resources. The composition of the command and general staff also indicates that the incident has escalated beyond simply being managed by a single Incident Commander or a smaller team, illustrating the need for specialized roles and responsibilities during extended response efforts.

In contrast, the other incident types represent varying levels of complexity and resource needs, with Type 3 typically addressing incidents with more defined and smaller operational requirements.
