What a full first alarm means
A "full first-alarm" response is the standard multi-unit dispatch for a structure fire, typically sending several engine companies, truck companies, and command staff to the incident. According to the City of San José, recent flash reports have used that phrase to describe this level of response.
Injuries and next steps
All occupants had already evacuated before firefighters arrived, but one patient required medical care at the scene, according to the San José Fire Department. The department did not release information on the cause of the fire or provide a damage estimate, and investigators had not shared additional details by mid-morning.
