London firefighters had left Grenfell Tower after putting out a refrigerator blaze – but it then flared up and raced through the 24-story building, according to a report.
The firefighters told residents that they extinguished the flames in the appliance before spotting the spreading conflagration from the outside, the BBC reported.
The June 14 disaster left 79 people dead.
The report was expected to add weight to claims that the cladding on the building’s exterior caused the flames to spread so quickly.
Four government ministers had been warned that fire regulations were not keeping residents safe, according to the BBC.
According to leaked letters, experts said that people living in high-rises like Grenfell Tower were “at risk.”
The letters sent by the All-Party Parliamentary Fire Safety and Rescue Group in the aftermath of a deadly 2009 fire in London’s Lakanal House warned that the government “could not afford to wait for another tragedy.”
“Surely … when you already have credible evidence to justify updating … the guidance … which will lead to saving of lives, you don’t need to wait another three years in addition to the two already spent since the research findings were updated, in order to take action?” the parliamentary group wrote in March 2014.
“As there are estimated to be another 4,000 older tower blocks in the UK, without automatic sprinkler protection, can we really afford to wait for another tragedy to occur before we amend this weakness?”
Meanwhile, the London Fire Brigade posted photos on Tuesday of Adele posing with firefighters in front of their engine at the Chelsea fire station after the tragedy.
“We are so humbled by everyone’s support,” the brigade tweeted.
