At least 1 killed, several injured when Texas plant releases hydrogen sulfide

One person died and several others were injured Thursday when a chemical was released at a Houston-area industrial plant, a Texas sheriff said.

Authorities warned nearby residents to stay inside and close doors and windows.

One of the people injured was transported to a hospital by a helicopter, Harris County Sheriff Ed Gonzalez wrote on the social platform X. City officials in Pasadena, a Houston suburb, told residents on social media that hydrogen sulfide had been released at a Pemex facility.
