The document provides an overview of the Incident Command System (ICS). It discusses the history and origins of ICS in the 1970s from the FIRESCOPE project. ICS can be used to manage both small and large emergency and non-emergency events. The key components of ICS include the incident commander, command and general staff, organizational structure with sections, branches, divisions and units, facilities like the incident command post, and concepts like the incident action plan, span of control, and unified command. ICS provides a standardized approach to the command, control, and coordination of emergency response.
