National Incident Management System: Incident Command System, Emergency Responder Field Operations Guide [open pdf - 631KB]
"The National Incident Management System (NIMS) provides a consistent nationwide template to enable Federal, State, tribal, and local governments, nongovernmental organizations (NGOs), and the private sector to work together to prevent, protect against, respond to, recover from, and mitigate the effects of incidents, regardless of cause, size, location, or complexity. NIMS represents a core set of doctrines, concepts, principles, terminology, and organizational processes that enables effective, efficient, and collaborative incident management. This consistency provides the foundation for utilization of NIMS for all incidents, ranging from daily occurrences to incidents requiring a coordinated Federal response. Homeland Security Presidential Directive 5 (HSPD-5), Management of Domestic Incidents, directed the development and administration of NIMS. The NIMS documents integrate best practices into a comprehensive framework for use by emergency management and response personnel in an all-hazards context nationwide. HSPD-5 requires all Federal departments and agencies to adopt NIMS and to use it in their individual incident management programs and activities, as well as in support of all actions taken to assist State, local, and tribal governments. State, local, and tribal governments are not required to participate in NIMS or adopt these best practices. As applied to non-Federal entities, NIMS documents contain guidance that is not legally binding. However, in order to participate in NIMS and to be considered NIMS compliant, it is necessary for entities to adhere to the standards, practices, and/or minimum criteria presented in the NIMS guidance documents."
