The balcony of a fourth-floor flat in a seven-storey block was damaged by the fire. There were no reports of any injuries.
The Brigade’s fire investigation team believe the fire was accidental and caused by the unsafe disposal of smoking materials.
A London Fire Brigade spokesperson said: “We’d rather you didn’t smoke at all, but if you are a smoker, it’s absolutely vital you ensure your cigarette is completely out when you’ve finished smoking it.
“If you don’t, you risk causing a fire which could not only destroy your home, but also cost you your life.”
The Brigade was called at 3.05am and the fire was under control by 3.47am. Fire crews from Deptford, New Cross, Greenwich and Lewisham fire stations were at the scene.
Safety advice for smokers:
- It’s safer to smoke outside, but make sure cigarettes are put right out and disposed of properly.
- Never smoke in bed and avoid smoking on armchairs and sofas – especially if you think you might fall asleep.
- Take extra care when you’re tired, taking prescription drugs or if you’ve been drinking alcohol.
- Use proper ashtrays, which can’t tip over and stub cigarettes out properly.
- Always empty ashtrays carefully.
- Make sure smoking materials are out, cold and preferably wet them before throwing into a bin – never use a wastepaper basket
