What happened
Firefighters from Folsom Fire Department, El Dorado Hills Fire Department and Sacramento Metropolitan Fire District responded to a structure fire on the 100 block of Loughridge Way in Folsom. Crews found heavy smoke inside the residence and traced the fire to a bedroom where flames had extended into a wall cavity. The fire was contained after opening wall sections and ventilating the attic. A residential energy storage system with an inverter and lithium batteries was present inside the home. Firefighters exercised added caution due to risks of explosion, toxic smoke and re-ignition. All occupants and pets were evacuated with no injuries reported. The cause remains under investigation.
Contributing factors
The presence of lithium batteries required additional safety measures during suppression, including full decontamination of personnel. It was not reported whether the battery system was the ignition source.
Lessons learned
- Residential battery systems require pre-incident planning for toxic smoke and re-ignition hazards.
- Full decontamination protocols should be applied when crews enter spaces containing lithium batteries.
- Early identification of energy storage equipment during size-up improves crew safety.
