Which Incident Type requires regional or national resources with up to 200 personnel per operational period?

The correct choice refers to Incident Type 2, which is characterized by its need for significant resources that may include regional or national assets. This level of incident typically involves a greater complexity and could require a combination of a higher number of personnel—up to 200 per operational period—along with extensive logistical support and management capabilities.

Type 2 incidents often arise from situations like large-scale disasters or large public events that require coordinated efforts across multiple agencies and jurisdictions. They necessitate a structured command organization and can overwhelm local resources, thus needing assistance from outside the immediate area.

Other incident types have differing requirements for resources and personnel. Type 1 incidents are even larger in scale, involving an extensive need for resources, sometimes exceeding 500 personnel, which sets them apart from Type 2 incidents. Type 3 incidents typically involve a smaller scope and can often be managed with local resources, while Type 4 incidents involve very limited resources and can usually be managed by a single resource. Understanding these distinctions helps in effective incident management and resource allocation within the ICS framework.
