Which incident type requires regional or national resources, 500 per operational period?

The incident type that requires regional or national resources, specifically 500 personnel per operational period, corresponds to Type 1 incidents. This classification is indicative of large-scale incidents that have a significant impact, often requiring extensive management capabilities, resources, and coordination efforts across various jurisdictions or regions. Type 1 incidents typically involve complex situations that necessitate a high level of operational capability, larger management structures, and support from agencies at the state or national level.

This classification is part of the Incident Command System (ICS) and serves to guide the allocation of resources and personnel needed to effectively manage such incidents. The scale of a Type 1 incident often involves extensive operational periods, usually requiring a strategic approach to ensure that all necessary resources are coordinated seamlessly to respond to the crisis effectively.

Understanding the specifics of what defines a Type 1 incident is crucial for incident commanders and emergency management personnel in order to adequately prepare for mobilizing substantial resources and ensuring a comprehensive response.
