San Francisco Fire Department crews responded to an extinguished lithium-ion battery fire in the 100 block of Fell Street, authorities said Saturday.
The fire, which was confined to a single room, produced smoke that prompted several residents to go to balconies, windows, and fire escapes to wait for help, according to the department.
All affected residents either sheltered in place or were assisted by firefighters and police officers. No formal rescues were required.
Officials noted that the fire was contained quickly due in part to a prompt response by the SFFD and active fire sprinklers.
The incident is under control, and no injuries or displacements have been reported, the department stated.
