Four fire engines and around 25 firefighters tackled a fire at a shop with flats above on Ripple Road in Barking.
Part of a ground floor shop was damaged by fire. 16 people from flats above left the building before the Brigade arrived. There were no reports of any injuries.
The Brigade's Control Officers took seven calls to the fire and used GoodSam to live stream incident footage from smart phone cameras to provide better situational awareness.
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.
The Brigade was called at 0705 and the fire was under control by 0815. Fire crews from Barking, East Ham, Ilford and Plaistow fire stations attended the scene.
The cause of the fire is under investigation.
