Two workers who were hurt Wednesday morning in a blast at an industrial plant near Houston.
They have been taken to a hospital as a precaution for what the company describes as inhalation injuries.
The explosion shook nearby homes, and sent up black smoke that was seen for miles.
Police say a tank at the American Acryl plant exploded just before 9 a.m.
Officials in the Houston suburbs of Pasadena and Seabrook told residents to stay indoors after the explosion, because the tank that exploded contained a toxic petroleum byproduct that is used in paint and gasoline.
The company says the cause of the explosion is being investigated.
