The NIMS managers start planning and preparing for the demobilization process when it is clear that the situation requires a collaborative approach that includes personnel from several organizations.

Explanation:

NIMS, or the National Incident Management System, is a special structure for managing multi-jurisdictional or large-scale incidents. It works and is being phased in at the local, state, and federal levels. The demobilization process establishes certain actions and responsibilities, releases procedures and priorities to return resources, operations, and facilities to the pre-incident state.

Every day, communities and organizations have to respond to a huge number of emergencies. Usually, these incidents may be and are coped with rather effectively at a local level. However, sometimes there are serious emergencies that require a collaborative approach. It means that to solve the problem, the rescue team has to include personnel from non-governmental organizations, multiple levels of government, several different jurisdictions, a combination of specialties or disciplines, and the private sector.

The National Incident Management System provides a proactive and systematic approach to help and guide a number of agencies and departments at all levels of the private sector and non-governmental and governmental organizations. It helps them to work hard to protect against, prevent, recover from, respond to, and reduce and soften the consequences of emergencies and incidents, regardless of their size, cause, complexity, and location. The main purpose is to reduce harm to the environment and the loss of people’s and animals’ lives and property. The National Incident Management System helps to find and keep the foundation that is necessary to make sure that people from different organizations are able to work together when the Nation, the country, and the society needs it.
