Three fire engines and around 15 firefighters were called to a fire at a house on Lady Somerset Road in Kentish Town.
A small fire started in the kitchen of an end of terrace house. One man left the building before the Brigade arrived. Firefighters wearing breathing apparatus led one woman to safety via an internal staircase from the third floor and rescued one man from the second floor of the building using a fire escape hood. Two women and one man were treated on scene by London Ambulance Service crews suffering from smoke inhalation.
Fire escape 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 was called at 0023 and the fire was under control by 0050. Fire crews from Kentish Town, Holloway and Euston fire stations attended the scene.
The cause of the fire is under investigation.
