Firefighters rescued a woman from a fire at a flat on Oakfield Road in Croydon.
A small part of a flat on the first floor of a three-storey block was damaged by the fire. Firefighters wearing breathing apparatus rescued one woman via an internal staircase. She was treated at the scene and taken to hospital by London Ambulance Service crews.
The Brigade's Fire Investigators believe the fire was caused by incense sticks.
A London Fire Brigade spokesperson said: “Candles, incense and oil burners are one of the most common causes of fire within homes. It’s really important that you never leave incense unattended and keep it away from curtains and anything else that can easily catch fire.
"These items should always be held firmly in heat-resistant holders and placed on a stable surface where they won’t be knocked over, and make sure you put them out entirely when you leave the room and especially before bed.”
The Brigade was called at 1218 and the fire was under control by 1316. Two fire engines and around 10 firefighters from Croydon and Norbury fire stations were at the scene.
