Unknown Odor Causes Symptoms, Roads Closed at Deer Park Industrial Site

Hazmat crews and local authorities responded to an industrial site on Tidal Road in Deer Park, Texas, after reports of an unidentified odor caused headaches and nausea among residents and workers. The odor, first detected Tuesday morning, prompted an internal shelter-in-place order at a neighboring facility and led to several road closures, including Tidal Road northbound and the westbound Highway 225 frontage road. Air quality monitoring by CTEH and updates from Harris County Sheriff Ed Gonzalez indicated that, as of mid-morning, air quality was considered safe and there was no threat to the broader community. Multiple agencies, including the Harris County Sheriff’s Office and environmental representatives from Shell Deer Park and Lubrizol Corporation, are investigating the source of the odor. Residents in the area have been advised to remain cautious and await further updates as the investigation continues. The incident remains under active investigation with officials working to identify the chemical involved.
