Five fire engines and around 35 firefighters were called to a fire at a mixed-use commercial and residential block on Yeo Street in Bow.
Crews tackled a small fire on a fifth-floor balcony. A woman was taken to hospital by London Ambulance Service crews.
The Brigade's 999 Control Officers took seven calls to the fire and used 999Eye to live stream the blaze from a smart phone to screens in the Control Room, allowing for greater visibility of the incident.
When a 999 call is received by the Brigade, the caller may be asked if they would like to provide a live video stream of the scene using their smartphone. The Control Officer will send a text message with a secure, one-time-use link that opens a live stream direct from the phone to the Control Room. 999Eye provides better situational awareness and allows us to offer the best advice based on live footage.
The Brigade was called at 2052 and the fire was under control by 2136. Fire crews from Poplar, Millwall, Bethnal Green and Shadwell fire stations attended the scene.
The cause of the fire is under investigation by the Brigade and the Metropolitan Police Service.
