Intrastate Mutual Aid System (IMAS)

With support from DHS' National Integration Center (NIC), the ultimate goal of IMAS is to support the development of comprehensive and functional mutual aid plans for the fire service in all states and, eventually, tribal nations and U.S. territories.

IMAS Technical Advisors (TAs) (pdf, updated 1/13/11)
Selected for their experience in mutual aid knowledge, planning and operation, each TA is assigned to work with project states on their IMAS planning process to develop or enhance their statewide mutual aid plans. Please contact IMAS staff to receive a TA's contact information.

Field Guide Development

To help states market and educate fire service personnel on their plan, the IAFC can assist in the creation of a pocket- sized field guide based on the response plan. Once agreed by the stakeholders, the states and localities are encouraged to distribute the field guides to their emergency response personnel. The following examples can be used as templates.

Tabletop Exercise Scenarios

Plan maintenance ensures that a state's plan is current and maintained as a working document.  Tabletop exercises can be used to identify gaps in a plan, train on a plan, and update appendices and forms.  View the scenarios below that have been created for conducting tabletop exercises.
