The Grenfell Tower fire started shortly before 1am BST on 14 June 2017 in a tall building or tower block, Grenfell Tower, in the Royal Borough of Kensington and Chelsea, West London, England. The fire killed 72 people. Grenfell Tower was built in 1974, and was used for housing people. The flats in the building were subsidized: meaning the government paid part or all of the of the people who lived there.
In the early hours of 14 June, 2017, a fire broke out in the building, which caused massive damage to nearly all of the building. The fire broke out around the 4th floor of the 23 floor building. It was signalled to police at 0:54 local time. The fire brigade took 6 minutes to get to the tower. In total, 70 fire engines, and more than 200 firefighters were trying to put out the fire. On the 14th of June, at the end of the day, the number of people injured (and taken to hospitals) was about eighty, about 20 were in a critical condition. About 72 people died in the fire. There could have been up to 600 people in the 120 one- and two-bedroom flats of the block at the time of the fire. The number of people that were in the building when the fire broke out is unknown; police have estimated around 200.
The fire started around 00:50 BST (UTC+1), when a fridge caught fire in flat 16 on 4th floor. Firefighters arrived around 1am, and put out the fire in the flat within minutes. When the crew were leaving the building, they spotted flames rising up the outside of the building. Images later presented to the Grenfell Tower Inquiry suggested that the fire may have reached the outside before the firefighters had begun to tackle the initial fire in flat 16. The flames spread up the side at a "terrifying rate", By 01:29, a rising column of flames had reached the roof and the fire was out of control.
Many people believe this rapid spread was due to the outside of the building, which had been changed recently. This cladding seemed to contain highly flammable material. Many residents complained about poor fire safety and other problems with the building, which was managed on behalf of the Royal Borough of Kensington and Chelsea. The residents' organisation, Grenfell Action Group, had repeatedly warned of major fire safety problems since 2013, and also noted past fires and fire-related incidents in similar blocks managed by the same company, which they felt were related to poor fire safeguards and management company fire policies. One of these policies told residents to stay in their flats in case of fire. The group warned in November 2016 that only a "catastrophic" fire would finally force the block's management to treat fire precautions and maintenance of fire-related systems to a proper standard.
Mayor of London Sadiq Khan said there were "questions that have to be answered" about the fire-safety conditions at the Grenfell Tower. Khan criticised the safety instructions telling people to stay in their flats in particular:
"We can't have people's lives being put at risk because of bad advice or lack of maintenance." The advice of staying in the flat assumes that firefighters can contain the fire inside the building, which is impossible if it is spreading rapidly via its outside. The advice may have proved fatal to many people.
A team of 250 firefighters from forty fire engines attempted to control the fire and rescue people. The first emergency services arrived six minutes after the alarm, but the fire's very high temperature slowed rescue attempts. At 04:14, officials from the Metropolitan Police addressed the large crowd of onlookers and urgently told them to contact anyone they knew who was trapped in the building—if they are able to reach them via phone or social media—to tell them they must try to self-evacuate and not wait for the fire brigade. Firefighters entered the building to try to rescue people but reported they were hindered by the extreme heat. According to witnesses, there were people trapped inside, waving from windows for help, some holding children. There were two witness accounts of parents dropping their children down to people below, including a baby who was caught after being thrown from the ninth or tenth floor, and a small boy thrown from the fifth or sixth floor. There were also eyewitness reports that some people were jumping out. At least one person used knotted blankets to make a rope and escape from the burning building. Frequent explosions that were reported to be from gas lines in the building were heard.
Many residents of the tower were Muslims. Because of Ramadan, many were awake at the late hour. Many were able to alert residents and help them escape during the early stages of the fire, which saved many lives. For this, they were hailed as heroes.
After three hours, the original crew of firefighters were replaced. By sunrise, the firefighters were still battling the fire and trying to spray areas where people were seen trapped. The watching crowd were pushed back from the building because of falling debris. At 05:00, the building was still burning and severely damaged. The fire continued to burn on the tower's upper floors into the afternoon of 14 June. Firefighters were expecting to continue tackling the blaze for at least a further 24 hours. Although fears were expressed that the building could collapse, structural engineers determined that it was not in danger and that rescue teams could enter it to search for survivors, casualties and bodies.
The cause of the fire has not yet been determined. Several media outlets reported that it may have been caused by a faulty kitchen appliance. A fourth-floor resident told the media that it was his neighbour's fridge that caught fire around 1:00 am, and that they immediately began knocking on doors to alert people. He said that within half an hour the building was entirely engulfed in flames.
Whilst there was much criticism of the lack of fire sprinkler systems, Geoff Wilkinson, the building regulations columnist for the "Architects' Journal", wrote in a comment on 14 June, before the cause was known ("we should avoid speculating"), that if a leaking gas riser or the cladding were at fault, sprinklers would have had little effect. He said he had seen extracts of a fire risk assessment and talk of flammable material stored in the common walkways, suggesting poor overall management.
The inhabitants of the building organised the Grenfell Action Group, years ago. They regularly pointed out problems with the building. In 2013, they published part of a report, where they showed that the protection against fire was insufficient in the building. Regulations require that these materials are checked regularly. According to the 2013 report of action group, there had been no such checks in the three years before the report.
When a building is on fire, people need to be able to get out quickly. Usually, there are specially signalled escape lanes for this. The action group pointed out that the escape lanes were not free, and people often parked their cars in such a way that the police was unable to get close to the building.
There had been various repairs and renovations in the building, from 2014 to 2016. The company who was responsible for these works said that they were shocked, at what had happened, and that at the time the works had been done, regulations had been met.
When the building was renovated, the materials used for the outside of the building were changed. Fire safety experts have speculated that this new material was a possible cause of the rapid spread of the fire. They said it essentially worked like a chimney in spreading the fire. The material could be seen burning and melting, causing additional speculation that it was not fire resistant. One resident said, "The whole one side of the building was on fire. The cladding went up like a matchstick."
