Four fire engines and 21 firefighters and officers were called to a fire at a house in Witley Road in Archway.
Half of the first floor of the property was damaged by fire. Two people left the property before the Brigade arrived. One person was treated at the scene and one was taken to hospital by London Ambulance Service, both suffering from smoke inhalation.
It is believed the fire was caused by the unsafe disposal of a cigarette into a bin
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.”
• Make sure you have smoke alarms fitted in every room you regularly use in your home including in the hallways.
• Never smoke in bed.
• Always ensure you stub out cigarettes properly and dispose of them carefully.
• Keep matches and lighters out of children's reach.
• Never leave lit cigarettes or cigars unattended.
• Empty ashtrays carefully, ensuring all smoking materials are stubbed out and cold.
• If you must smoke, do it outdoors.
The Brigade was called at 1449 and the fire was under control at 1546. Fire crews from Kentish Town, Hornsey and Islington fire stations attended the scene.
