Firefighters have issued a smoking safety reminder after a fire at a flat on Station Way, Woolwich.
Firefighters wearing breathing apparatus rescued a woman from the third floor flat. She was suffering from smoke inhalation and was taken to hospital by London Ambulance Service crews.
The Brigade's fire investigation team believe the fire was accidental and due to the unsafe disposal of a cigarette.
A London Fire Brigade spokesperson said: "We would rather people didn’t smoke at all but if they do, vaping is a safer option.
"If you do choose to smoke cigarettes, it is 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."
A small part of the flat was damaged by fire.
The Brigade was called at 2327 and the fire was under control at 0013. Fire crews from Plumstead fire station attended the scene.
