A woman is still recovering in hospital after a blaze broke out in her Holloway home, which is thought to have been caused by an unattended chip pan.
Part of the ground floor of the terraced house in Ronalds Road was damaged by fire.
Two women and a man left the building before the arrival of the London Fire Brigade (LFB).
They were treated at the scene for smoke inhalation by ambulance crews, and one of the women was taken to hospital.
The LFB was called just before midnight and about 25 fire fighters using four fire engines had the fire under control an hour later.
Station officer Wayne Sharp, who was at the scene, said: “On arrival crews were faced with heavy smoke and worked quickly to bring the fire under control and stop it from spreading.
“Chip pans and cooking with hot oil can be really dangerous and the risk increases when you start frying food more than once.
“All it can take is for you to become distracted for a few seconds and your cooking oil can quickly go up in flames.”
He added: “Fires are more likely to start in the kitchen than any other room in the home.
"Cooking should never be left unattended on the hob or grill - if you have to leave the kitchen, turn off the heat."
Fire crews from Holloway, Islington, Stoke Newington and Kentish Town fire stations attended the scene.
Practical steps for safer cooking:
- Take extra care when cooking with hot oil as it can easily overheat and catch fire.
- Never fill a pan more than one third full of fat or oil.
- Make sure food is dry before putting it in hot oil – oil and water are a dangerous mix.
- If the oil starts to smoke, it’s too hot. Turn off the heat and leave it to cool.
- Try not to leave cooking unattended on the hob or grill – if you have to leave the kitchen, turn off the heat.
