NFIRS 5.0 Element: ‘Aid Given or Received’

Définition : Aid given or received, either automatically (i.e., prearranged) or mutually for a specific incident.
These actions are defined as:

  • Aid Received (automatic or mutual) : A fire department handles an incident within its jurisdiction with additional manpower or equipment from one or more fire departments outside its jurisdiction. Aid received can be either mutual or automatic aid.
  • Aid Given (automatic or mutual) : A fire department responds into another fire department’s jurisdiction to provide assistance at an incident or to cover a vacated station while the receiving fire department is busy at an incident. Aid given can be either mutual or automatic aid.
  • Other Aid Given : A fire department covers and responds to another jurisdiction or locale that has no fire department.
  • No Aid : A fire department handles an incident within its jurisdiction without help from adjacent or outside fire departments.
Purpose : Aid information can be used to study response levels necessary to control various fire and emergency situations. It can be used to determine the adequacy of resources at the local level and the need for adjusting cooperative agreements. The Aid Given or Received entry serves as data control to ensure that the same incident is not counted more than once while still giving credit for activity performed by outside departments.
Entry : Check or mark the box indicating whether aid was given or received. If no aid was given or received, check or mark the None box
