Final answer:
NIMS is indeed a comprehensive national approach to incident management, integrating various organizations for a coordinated response to domestic incidents.
Step-by-step explanation:
The statement 'NIMS is a comprehensive national approach to incident management' is True. The National Incident Management System (NIMS) provides a consistent nationwide template to enable all government, private-sector, and non-governmental organizations to work together during domestic incidents. This approach allows for the integration of best practices and ensures that responses to incidents are coordinated and comprehensive.
NIMS encompasses a wide range of incident management activities including preparedness, communications and information management, resource management, and command and management. It is applicable across a full spectrum of potential incidents and hazard scenarios, regardless of size, location or complexity.
