At least two people were killed and several others were injured in a chemical leak at a Texas LyondellBasell facility, authorities said.
Thirty-one people were being evaluated for injuries and symptoms, five were being treated on scene and one person was transferred to the hospital by LifeFlight and another by ambulance, she said.
"We don't really know much about it. We don't know how it occurred but we do know we have injuries and we do know we have fatalities," she said.
Christensen had said the leak was caused by a small explosion in the plant, but her office later clarified that investigators had ruled out an explosion as the cause of the leak following a preliminary inspection of the site.
All personnel working within the unit where the leak occurred have been accounted for,
"The leak is stopped and clean-up is in progress," the company said.
