Firefighters tackled a flat fire on Devonshire Hill Lane in Tottenham.
Part of a four-roomed flat on the first floor of a block of flats was damaged by fire. One man left the building before the Brigade arrived. Firefighters wearing breathing apparatus led a man and a woman to safety via an internal staircase. One man was treated on scene by London Ambulance Service crews.
The fire is believed to have been accidental and caused by the failure of a lithium-ion battery.
A London Fire Brigade spokesperson said: “Batteries can present a fire risk if they’re over-charged, short circuited, submerged in water or damaged, so it’s really important to protect them against being damaged and charge them safely.
"Unplug devices once they have finished charging and always make sure you use the right charger for your device.”
The Brigade was called at 1414 and the fire was under control by 1433. Three fire engines and around 15 firefighters from Tottenham, Southgate and Edmonton fire stations attended the scene.
