What characteristic is typically used to categorize resources in NIMS resource typing?

In the context of NIMS resource typing, the characteristic used to categorize resources is capability. This classification emphasizes the specific functions or tasks that resources can perform during an incident. By focusing on capability, emergency management agencies can ensure that the resources deployed are equipped to meet the operational needs of an incident effectively.

Capability-based categorization allows for a more organized and efficient response, as it aligns resources directly with the requirements of the situation at hand. For example, understanding whether a particular type of fire apparatus is intended for structural firefighting versus wildland firefighting helps incident commanders make informed decisions about resource allocation and deployment.

While availability, filter criteria, and cost efficiency might be considerations in overall resource management and logistics, they do not serve as the primary characteristic for resource typing within the framework of NIMS. Therefore, capability is the key aspect that guides how resources are identified, categorized, and utilized effectively during emergency response efforts.
