A fire ripped through one of the world’s tallest residential towers – popularly known as The Torch tower – in Dubai on Friday.

Flames shot up the sides of the tower in the second blaze to hit the high-rise since 2015, forcing hundreds of occupants to flee as burning debris showered down the sides of the 337 meter-tall, 79-storey structure.

“We were sleeping and we woke up to the fire alarm and people screaming. We ran down the stairs and it took us about 10 minutes to reach from the 50th floor,” a resident who gave his name as George told Reuters.

“It was very bad. The fire was very strong at that time, about 1 am. Then it started calming down over the next two hours,” he added. The tower was evacuated, no injuries were reported, and there was no immediate word on the cause of the blaze.

An investigation by the management of the Torch after its 2015 fire found that most of the damage was to the cladding, exterior paneling used for decoration or insulation.

Police in Britain have said they believe the system of insulation and cladding panels added during a refurbishment of London’s Grenfell Tower may have contributed to the rapid spread of a fire there in June in which 80 people died.

The UAE revised its building safety code in 2013 to require cladding on all new buildings over 15 meters (50 feet) tall be fire-resistant, but older buildings are exempt. Most of Dubai’s approximately 250 high-rise buildings use cladding panels with thermoplastic cores, UAE media have reported. Panels can consist of plastic or polyurethane fillings sandwiched between aluminum sheets.

 Such cladding is not necessarily hazardous, but it can be flammable under certain circumstances and, depending on a skyscraper’s design, may channel fires through windows into the interiors of buildings. Dubai’s civil defense authorities said firefighting squads put out the blaze around 4.00 am (0000 GMT) and were cooling the building.

Firefighters and police sealed off surrounding streets, which were partially covered by dust and debris. By 4 am the exterior of the building showed no sign of fire as residents and onlookers stood around staring up at the building, according to a Reuters witness.

Shelter
Another resident, whose gave his name as Mohammed and lives on the 12th floor, said the top part of the tower caught fire first and then lower levels followed as debris fell. The government said it was working on providing shelter for those affected by the fire.

In August 2016 a fire swept through a 28-storey building under construction in the UAE capital, Abu Dhabi, injuring 13 people, including 10 emergency service personnel.

Earlier that same month, a fire damaged part of a multi-story building under construction in Dubai and in July 2016 a fire broke out in Dubai’s residential 75-storey Sulafa Tower. On New Year’s Eve 2015, a blaze hit a Dubai hotel.

This is not the first fire to hit the tower. In 2015, hundreds of people were evacuated from the a 79-story skyscraper when a fire broke out.
