Description: The DFD Fire Investigation Division (FID) is tasked with investigating all intentional (arson) and accidental fires to determine the origin, cause, and circumstances of fires within the city. Fire investigations serve not only to document the circumstances associated with fires, but also contribute to development and implementation of fire prevention strategies and programs. Fire investigations are conducted according to the City of Detroit Fire Prevention and Protection Code (Detroit City Code Chapter 18), the State of Michigan Fire Prevention Code (Act 207 of 1941), and NFPA (National Fire Protection Association) Standards 921 (Guide for Fire and Explosion Investigations) and 1033 (Professional Qualifications for Fire Investigator).
Each row in the dataset represents a fire investigation, and includes data about investigation status, when and where the fire occurred, when the investigation started, the primary cause (‘determination’) of the fire, and civilian injuries and fatalities associated with the fire. Fire Investigation records can be linked to Fire Incident records using the fire incident number. Note that if DFD was not called to the fire under investigation (about 2-3% of investigations), a fire incident number is not included in the investigation record. This occurs if, for example, DPD rather than DFD is dispatched because a fire that was extinguished is reported.
The Fire Investigations dataset is updated daily and includes records from 2019 to the present.
