A chemical leak at the Röhm USA facility in Matagorda County injured multiple workers Friday afternoon after a valve failure in a brine cooler released ammonia into the plant and air. Ten workers were hospitalized, one by helicopter, while others received precautionary treatment on-site. Emergency systems activated as designed, preventing further risk. Officials confirmed there was no danger to the public. Bay City Volunteer Firefighters, local EMS, and agencies from Houston responded swiftly. Röhm, a German chemical company, recently opened the facility at the OQ Chemicals site. Authorities are investigating the cause of the leak.
