Six fire engines and around 40 firefighters were called to a fire at a flat on Callender Road in Erith.
An electric scooter in a first floor corridor was destroyed by fire. Around 60 people left the building before the Brigade arrived. One woman and a child were treated on scene by London Ambulance Service crews.
The Brigade's 999 Control Officers gave vital fire survival guidance advice to residents inside a first floor flat on how to stay safe before crews arrived.
The Brigade’s Fire Investigators believe the cause of the fire involved an electric scooter which was on charge.
Station Commander Gary Wilson, who was at the scene, said: “Crews arrived to find an electric scooter in a communal corridor alight. Firefighters wearing breathing apparatus led two adults and two children from a flat on the first floor to safety.”
“There was heavy smoke inside the building and firefighters worked quickly to bring the fire under control and prevent it from spreading and causing further damage.”
The Brigade was called at 0047 and the fire was under control by 0124. Fire crews from Erith, Bexley, Plumstead and surrounding fire stations attended the scene.
