A house fire broke out in the early hours of the morning in Hillingdon, prompting a response from four fire engines and approximately 25 firefighters from nearby stations in Hillingdon, Ruislip, Hayes, and Northolt.
Firefighters were dispatched to Grosvenor Crescent at 5:16am to tackle the blaze which is believed to have been accidental and damaged part of the first floor of a mid-terraced house.
A woman escaped the property before the fire brigade arrived and was treated on the scene by paramedics for smoke inhalation.
The fire was under control by 6:47am.
The fire is thought to have been caused by the failure of a lithium-ion battery in a medical cushion.
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.”
