2 workers unaccounted for after massive 5-alarm fire at Charlotte, North Carolina, construction site

Two workers are unaccounted for after firefighters battled a massive, five-alarm blaze that broke out Thursday morning at a construction site in Charlotte, North Carolina.

More than 90 firefighters were called to the scene and had not yet extinguished the fast-moving flames, said Charlotte Fire Chief Reginald Johnson at a news conference held hours after flames initially erupted around 9 a.m. ET. Exposed wood at the construction site allowed the fire to move quickly, reaching scorching temperatures well over 2,000 degrees Fahrenheit, according to the chief.

Crews rescued 15 workers from the blaze, Johnson said. Fire officials previously told CBS News that a tower crane operator, who was working at the construction site when the fire broke out, was rescued and safely on the ground. The operator was transported to a hospital with injuries that are not life-threatening.

Johnson said two workers remained unaccounted for at the time of the news conference, citing confirmation from the construction site foreman.

Videos and images shared on social media show bright orange flames engulfing part of a large building complex in the North Carolina city’s South Park neighborhood, an area known for its large namesake shopping center. Additional footage taken by CBS affiliate WBTV captured a thick plume of black smoke rising up from the burning structure. 

Huge flames are seen billowing out from the roof of the structure in a separate video, recorded by the Twitter user @mr_veal from inside a building across the street.

Charlotte-Mecklenburg Police announced multiple road closures in the SouthPark area in a tweet after the fire broke out. At least one road has since been reopened. A spokesperson for Charlotte-Mecklenburg Schools told WBTV on Thursday morning that schools had not been impacted by the blaze.

Fire crews will likely remain on scene for “a period of time,” according to the chief, who said at the afternoon conference that responders had already called mayday — which happens when crews are trapped or otherwise have issues escaping — twice since arriving. Investigators will determine what caused the fire, he said.

Mill Creek Residential, which is developing the property under construction in South Park, said  in a statement to CBS News that the company was “gathering as much information as possible on what occurred” at the site.

“Our No. 1 priority is the health and safety of the people who were working there today and those in the surrounding area,” the company said. “Our thoughts are with those who were impacted and their friends and family members. We are gathering as much information as possible on what occurred and will take the appropriate measures to address today’s incident.”
