Authorities in Denver, Colorado, confirmed a fire at Empower Field at Mile High on Thursday. There were no injuries and the fire was later put out.
“A small fire that occurred in a construction zone near the East Club Lounge at Empower Field at Mile High has been contained by @Denver_Fire. That area of the stadium was quickly evacuated as a precaution and there were no injuries sustained,” Empower Field at Mile High wrote in a tweet.
The Denver fire department posted photos on Twitter showing flames engulfing seats and black smoke emitting from the stadium, which hosts the Denver Broncos.
“Sprinklers attempted to stop the fire, but firefighters were needed to complete extinguishment. Heavy fire & smoke was found on our arrival,” the Denver Fire Department wrote on Twitter.
The cause of the fire is unknown, said the fire department.
Stadium officials said in a statement on Twitter that the fire occurred in a construction zone near the East Club Lounge. About 100 people were attending an event on the second level, but the stadium was otherwise empty.
Capt. Greg Pixley, a spokesman for the fire department, said it appears the fire originated in the suite and spread to the seats, which are made of plastic.
“This type of plastic that the seats are composed of burns with not only significant ferocity ... but also produces a tremendous amount of black smoke,” he said.
