Incident Management | Ready.gov

The National Incident Management System (NIMS) was established by FEMA and includes the Incident Command System (ICS). NIMS is used as the standard for emergency management by all public agencies in the United States for both planned and emergency events. Businesses with organized emergency response teams that interface with public emergency services can benefit from using the ICS. ICS is also well suited for managing disruptions of business operations. Public information and crisis communications are an integral part of the ICS structure.
