SAN ANGELO, TX — At least two employees were taken to a local hospital, but the extent of their injuries is not known.
Firefighters say bromate chemical compounds were burning inside the plant for hours.
Building alarms sounded as the fire broke out at the company that manufactures chemicals for oilfields.
A man who lives near the plant says there was an explosion so powerful it shook the ground.
Emergency crews were able to put the fire out before sunrise and after monitoring the air determined any risk to be over.
