NFIRS 5.0 Element: ‘Incident Type’

Definition: The incident type specifies (with precision) the category of incident, leading to exactly what additional information (modules, transaction) are required.

Purpose: This critical information identifies the various types of incidents to which the fire department responds and allows the fire department to document the full range of incidents it handles. This information can be used to analyze the frequency of different types of incidents, provide insight on fire and other incident problems, and identify training needs.

Entry: The type of incident reported here is not always the same as the incident type initially dispatched. This element determines which modules will subsequently be completed. Enter the three-digit code and a written description that best describes the type of incident. This entry is generally the type of incident found when emergency personnel arrived at the scene, but if a more serious condition developed after the fire department arrival on the scene, then that incident type should be reported.
