Ammonia Gas Leak from Tanker Truck in Oklahoma Sickens Dozens

A major ammonia gas leak in Weatherford, Oklahoma has left dozens hospitalized, hundreds evacuated from their homes, and an entire community shaken. The leak originated from a tanker truck loaded with anhydrous ammonia that was parked overnight at a hotel commonly used by oilfield workers. Early reports indicate that at least 35 people have been hospitalized due to chemical exposure, with many more experiencing symptoms such as difficulty breathing, burning eyes, throat irritation, and nausea.

Authorities confirmed that the truck and its cargo belonged to Airgas, a Houston-based chemical and industrial gas supplier. Because the company is headquartered in Texas, victims may have the option to bring claims in Texas state courts.

Weatherford Ammonia Spill- What Happened?

According to multiple Oklahoma news outlets, emergency crews responded early Wednesday morning after a strong ammonia odor spread through the area surrounding the hotel where the tanker was parked. Residents across several blocks were ordered to evacuate their homes as the gas dispersed through the neighborhood.

Ammonia is a dangerous, corrosive chemical that can cause serious respiratory injuries, long-term lung damage, chemical burns, and—in high concentrations—can even be fatal.

Several key facts have been confirmed:

• The ammonia leak came from a tanker truck carrying anhydrous ammonia, a hazardous industrial chemical.

• The truck was stationed at a hotel often utilized by oilfield workers and contractors.

• Airgas, headquartered in Houston, owned and operated the truck and the ammonia cargo.

• At least 35 individuals were hospitalized, including multiple oilfield workers staying at the hotel.

• Hundreds of residents were evacuated due to the threat of toxic exposure.

Local law enforcement and environmental agencies are continuing to investigate the cause of the leak and whether proper safety protocols were followed.

Who Is Affected?

Early reports suggest a large portion of the hospitalized victims are oilfield workers who were staying at the hotel. Many of these workers may not live in the immediate Weatherford area—they often travel across Oklahoma, Texas, and Arkansas for temporary assignments.

Residents in nearby homes and families staying in the area were also exposed.

If you live in or near Weatherford—or know someone who was affected—common symptoms of ammonia exposure include:

• Severe coughing or shortness of breath

• Chest tightness

• Wheezing or trouble breathing

• Eye, nose, or throat burning

• Skin irritation or chemical burns

• Nausea or dizziness

Even if symptoms seem to improve, ammonia exposure can cause delayed respiratory problems, meaning victims should be evaluated by a medical professional.

Airgas May Face Liability

Because Airgas is a Houston-based corporation, those harmed in this chemical spill may be able to file claims in Texas state courts. This includes:

• Oilfield workers traveling for work

• Hotel guests who were exposed

• Local Weatherford residents

• Individuals who sought emergency medical treatment

• Anyone who inhaled ammonia or was forced to evacuate

Our team is speaking with attorneys in Oklahoma evaluating potential cases and gathering updated information as the investigation continues.

What Victims Can Do Next

Individuals who were exposed—especially those experiencing symptoms—should:

1. Seek medical attention immediately, even if symptoms seem mild.

2. Document symptoms, medical visits, and any time missed from work.

3. Take photos of clothing, surroundings, or anything affected by the chemical odor.

4. Write down a timeline of what you experienced (odors, evacuation, symptoms).

5. Speak with a lawyer familiar with chemical exposure cases.

Oilfield workers who travel for work may also have additional protections under workplace injury laws, employer negligence claims, or third-party liability statutes.
