* Well below Edison's usual volume. That almost always means one or more departments didn't submit a full year to NFIRS, not that fires dropped, so no year-over-year change is shown for it.
For the 3 building fires Edison departments responded to in 2025, here's how they were classified once investigators were finished.
NFIRS Area of Origin (AREA_ORIG) for the 10 building fires investigators classified across 2021–2025. The room or location where ignition occurred — kitchens, bedrooms, exterior, vehicle areas — tells you where to focus prevention.
| # | Area of origin | Count | Share | |
|---|---|---|---|---|
| 1 | Undetermined | 5 | 50.0% | |
| 2 | Engine area, running gear, wheel area | 2 | 20.0% | |
| 3 | Bathroom, checkroom, lavatory, locker room | 1 | 10.0% | |
| 4 | Open area - outside; included are farmland, field | 1 | 10.0% | |
| 5 | Wildland, woods | 1 | 10.0% |
NFIRS Heat Source (HEAT_SOURC) — the physical thing that started it. Spark or ember from operating equipment, an open flame, smoking materials, or hot embers from a fireplace are the leading culprits nationwide. Here's the Edison mix.
| # | Heat source | Count | Share | |
|---|---|---|---|---|
| 1 | Undetermined | 9 | 90.0% | |
| 2 | Cigarette | 1 | 10.0% |

Numbers reflect incidents reported by participating fire departments to the National Fire Incident Reporting System (NFIRS) Public Data Release for calendar year 2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Per-capita comparisons use 2023 ACS population estimates. Wildland fire data complements NFIRS with NIFC and USFS perimeters. Active-fire counts come from a dated NIFC snapshot, not a live feed.
