NTSB to Investigate Weatherford Ammonia Leak

Hazardous Release Triggers Major Response

A tanker truck carrying approximately 25,000 pounds of anhydrous ammonia leaked late Wednesday night in Weatherford, Oklahoma, prompting the evacuation of hundreds of residents, hospitalisation of dozens, and a major response by local, state and federal agencies. According to authorities, the truck was parked in the lot of a hotel when a mechanical failure — likely a faulty seal or valve — caused the release of the toxic gas.

Evacuations, Hospitalisations and School Closures

Responders ordered a shelter-in-place for nearby homes and relocated some residents to local shelters including at the university. At least 34–36 people were hospitalised, including 11 in critical condition. Public and private schools, as well as university classes at Southwestern Oklahoma State University, were cancelled due to the chemical risk.

Federal Probe and Environmental Monitoring

The National Transportation Safety Board (NTSB) is now investigating the incident. As part of the probe, officials are looking into the truck’s condition, cargo handling and the sequence of events that led to the release. Meanwhile, the Environmental Protection Agency (EPA) is conducting air-quality monitoring and evaluating soil and water impact near the site. Initial results indicate no detectable ammonia in residential areas, though cleanup efforts may continue for days.

Community Impact and Next Steps

Weatherford (~12,000 residents, about 70 miles west of Oklahoma City) is dealing with the aftermath of the spill and a heavy emergency response. Officials warn that while immediate danger has diminished, residents exposed to the chemical should remain alert for symptoms such as respiratory distress, skin irritation or vision problems. The cleanup zone remains active and businesses in the impacted area are undergoing safety checks.
