Firefighters have issued a reminder of their candle and incense safety advice following a fire at an opticians with flats above on Becontree Avenue in Dagenham.
A small part of the ground floor was damaged by fire. A woman was taken to hospital after suffering from smoke inhalation.
The fire is believed to have been accidental and was caused by an unattended incense stick.
A London Fire Brigade spokesperson said: "Incense sticks, candles and oil burners are one of the most common causes of fire within homes. It’s really important that you never leave these items unattended.
"Make sure you place incense sticks in a suitable, fire-resistant holder and keep them away from curtains and anything else that can easily catch fire. Remember to put them out entirely when you leave the room and especially before bed.
"We also recommend taking some time to carry out a few simple checks to keep yourself and your loved ones safe. The Brigade’s online Home Fire Safety Checker can guide you around your home and provide you with specific advice to reduce fire risks.”
The Brigade's Control Officers were called at 1051 and mobilised four fire engines and around 25 firefighters from Dagenham, Hornchurch, Ilford and Tottenham fire stations to the scene. The fire was under control by 1136.
