A hydrogen sulfide release at the PEMEX refinery in Deer Park, Texas, resulted in one fatality and several injuries. Harris County Sheriff Ed Gonzalez confirmed the death and noted that another victim was airlifted to a hospital. The incident prompted a shelter-in-place order for Deer Park and Pasadena, urging residents to stay indoors and shut off air-conditioning until further notice. The release was contained within the facility, posing no threat to the broader community. Investigations are underway to ascertain the cause of the chemical leak, and PEMEX has initiated emergency protocols. The City of Pasadena lifted the shelter-in-place after confirming no community impact, although Deer Park's order remains as a precaution.
