National Incident Management System [NIMS] Law and Legal Definition

National Incident Management System or NIMS is a system prescribed by Homeland Security Presidential Directive 5 to coordinate emergency preparedness and incident management among various federal, state, and local agencies. NIMS provides a uniform nationwide approach to work effectively and efficiently together to prepare for, respond to, and recover from domestic incidents no matter what the cause, size or complexity, including catastrophic acts of terrorism and disasters. It is a system that is commonly used in U.S. Federal agencies also are required to use the NIMS system in domestic incident management and in support of state and local incident response and recovery activities.
