This morning, inside San Francisco's alarm office, it turned chaotic when embers from a fireplace reportedly sparked a small blaze that staffers had to battle by hand. With no running water available in the room, an employee identified only as "Kelly" resorted to using water from broken battery jars to douse the flames. The incident left parts of the city's alarm system down while crews moved in to secure equipment.
According to the San Francisco Department of Emergency Management, embers from a fireplace ignited inside the alarm office, batteries were damaged and wires went "silent," and Kelly used water from broken battery jars to put out the fire. The department noted that the office did not have running water during the incident and said crews were on scene securing the area. The initial message did not list any injuries.

Battery jars and an unexpected echo from 1906
Glass "battery jars," containers once used in lead‑acid cells to power telegraph and early alarm systems, show up in historical accounts of alarm room emergencies, when broken cells could complicate firefighting and even flood rooms. A historical account from the SF Museum describes how broken battery jars and disrupted water supplies affected the Fire Alarm office after the 1906 earthquake, a reminder that old equipment can create unusual challenges in critical control rooms. That history helps explain why improvised steps like using battery jar water can surface in a crisis even today.
What officials say and what remains unclear
The emergency management post focused on the immediate response inside the alarm office and did not specify whether alarms across the city failed or how long systems were offline, per the San Francisco Department of Emergency Management. City fire and utilities agencies had not posted detailed follow ups in the initial notice, and the department said crews were on scene securing equipment. Reporters and residents will be watching for official updates about system restorations and any investigation into the cause.
