Which characteristic is typically used to categorize resources in NIMS?

In the context of the National Incident Management System (NIMS), resources are categorized primarily by their capability. This refers to the specific functions, skills, and competencies that a resource possesses to effectively respond to incidents. For example, a fire engine's capability may include firefighting, rescue operations, or hazardous materials management. By organizing resources based on their capabilities, incident management teams can assess and deploy the right resources to meet the needs of a particular situation, ensuring that the response is effective and efficient.

This emphasis on capability allows for a clearer understanding of what each resource can do and enhances coordination between various agencies and organizations during an incident. Being able to quickly identify a resource's capability helps streamline operations and fosters better collaboration among different sectors involved in emergency management.
