Firefighters are issuing a reminder about their lithium-ion battery safety advice following a fire at a flat on Lanark Square on the Isle of Dogs.
Part of a second-floor flat, situated within a four-storey residential building, was damaged by fire. Three people were left in the care of London Ambulance Service to be treated for smoke inhalation.
The fire is believed to have been caused by the failure of lithium-ion battery for a power bank that was on charge.
A London Fire Brigade spokesperson said: “Lithium batteries are susceptible to failure if incorrect chargers are used, so it’s important to always use the correct charger for the product and buy an official one from a reputable seller.
"You should unplug your charger when you have finished using it and we would advise not to leave it unattended or charging while people are asleep.
“Batteries can present a fire risk if they’re over-charged, short circuited, submerged in water or damaged, so it’s really important to protect them against being damaged too.
“Try to ensure they are not getting knocked around while in use or while being carried as this can increase the chance of damage to cells."
The Brigade was called at 2350 and Control Officers mobilised crews from Millwall, Poplar, Whitechapel and East Greenwich fire stations to the scene. The fire was extinguished by 0149.
