GATESVILLE, Texas (CBS) -- One person was killed and 12 others were injured during an explosion at a hospital in Gatesville, Texas, authorities said Tuesday. First responders and emergency crews swarmed the area trying to reach the injured at Coryell Memorial Healthcare System.
Coryell Memorial Hospital CEO David Byrom confirmed the number of those injured Tuesday and said the hospital has been shut down. He said patients were being sent other hospitals in the area.
An eyewitness recorded black smoke billowing after the explosion on hospital grounds. The blast was so loud, it shook walls and knocked out power in parts of town, a witness said.
Initial reports said the blast occurred in an area where the hospital is being expanded. Investigators are looking into a boiler room that was under construction.
Two medical facilities, the Oaks at Coryell and the Meadows, were evacuated.
"I was on Levita Road picking up my dogs when I heard this loud noise, and by the time I got up to Memorial Drive, there were all kinds of police and fire trucks headed that way," local attorney Tanya Place told CBS affiliate KWTX. "There's a lot of smoke."
Another witness, who asked to remain anonymous, told the station there was an electrical generator that blew up and "scattered stuff all over the place."
