Fire origin and ignition circumstances

The public PDR Fire Incident table supplies Area of Origin, Heat Source, Item First Ignited, Confined to Origin, Type of Material, Cause of Ignition, two ignition-factor fields, eight human-factor fields, and fire spread. These records share the incident key with dated Basic Incident and Incident Address records, allowing the coded circumstances to resolve to the documented fire event. They are reported coded facts, not an expert causal opinion or legal finding; preserve the coding dictionary and version and distinguish missing or unknown codes from negative findings.

The anonymous SODA API and full export are pointable by caller-selected address and incident date. Official metadata exposes area and floor of origin, ignition cause and factors, heat source, first item ignited, and human factors, directly answering recorded origin and ignition circumstances for covered San Francisco incidents.
