How the Call Was Routed
The Citizen safety app, referenced by SFFD in its update, frequently surfaces early reports and live video from active scenes. On its homepage, the app describes its role in pushing real-time alerts and on-scene video to nearby users and responders, which helps explain why fire officials pointed to it in their post: Citizen.
What Neighbors Should Do
People in the area are urged to avoid the affected block while firefighters and other crews continue their work and to follow directions from first responders. For emergencies, call 911.
