Firefighters are urging smokers to dispose of cigarettes carefully after a fire at a shop with flats above on High Road in Leyton.
Part of the ground floor of a vacant shop and part of the first floor were damaged by fire. Around three tonnes of mixed refuse at the rear of the property was alight. There were no reports of any injuries.
The Brigade's 999 Control Officers took nine calls to the blaze.
The Brigade's Fire Investigators believe the fire was caused by the unsafe disposal of smoking materials.
A London Fire Brigade spokesperson said: “Fires caused by smoking materials including cigarettes, roll-ups, cigars and pipes, result in more deaths than any other type of fire. Stub cigarettes out properly and always dispose of them carefully.
“Make sure smoking materials are cold before emptying ashtrays. Preferably wet stubs before throwing them into a bin.”
The Brigade was called at 2144 and the fire was under control by 2322. Four fire engines and around 25 firefighters from Leyton, Leytonstone, Homerton and Stratford fire stations attended the scene.
