The Harris County Sheriff’s Office said on its Twitter feed the deputy had been taken to the hospital and nine others drove themselves to the hospital as a precaution.

The company evacuated remaining workers at the damaged plant on Tuesday, and Harris County ordered the evacuation of residents within a 1.5-mile (2.4-km) radius of the plant, which makes organic peroxides used in the production of plastic resins, polystyrene, paints and other products.
