Five fire engines and around 35 firefighters tackled a flat fire on Australia Road in Shepherd's Bush.
A first-floor flat was destroyed by fire. Firefighters wearing breathing apparatus rescued two people from the building using fire escape hoods. Seven people were taken to hospital by London Ambulance Service crews and a further five people were assessed on scene.
London firefighters were among the first in the UK to carry fire escape hoods when they were introduced in 2018 as part of improvements following the Grenfell Tower fire. The hoods provide members of the public with up to 15 minutes protection from four of the main fire gases (carbon monoxide, hydrogen cyanide, hydrogen chloride and acrolein) and can be worn by conscious or unconscious people. If more than 15 minutes protection is required then another hood can be given to each wearer. They do not provide oxygen but temporarily filter toxic smoke to make breathing easier.
The Brigade's Control Officers took more than 25 calls to the fire and provided vital fire survival guidance to those inside the building on how to stay safe until firefighters arrived.
The Brigade was called at 2357 and the fire was under control by 0203. Fire crews from Hammersmith, Kensington, Acton, North Kensington, Ealing and Battersea fire stations attended the scene.
The cause of the fire is under investigation.
