An explosion rocked a west Texas refinery Friday, injuring at least 19 people and sparking a blaze that sent a huge black cloud billowing into the sky.
Three people with burns were in critical condition Friday night, a nursing supervisor said. Sixteen others were hospitalized, mostly for smoke inhalation, and all but four were released by late Friday, a hospital official said.
No fatalities were reported and all employees at the Valero McKee Refinery were accounted for, said Valero Energy Corp.
