Hundreds evacuated and dozens hospitalized after an ammonia gas leak in Oklahoma
Overview
A tanker truck began leaking anhydrous ammonia shortly before 10 p.m. on Wednesday in Weatherford, Oklahoma, behind a Holiday Inn Express, releasing dangerous gas into the air.
The hazardous gas prompted the evacuation of 500-600 residents, closure of schools and nursing homes, and led to 36 hospitalizations due to respiratory distress and chemical exposure.
Anhydrous ammonia, a colorless gas with a suffocating odor, is highly hazardous, causing burns and severe health issues, and can be fatal at high concentrations, hindering dissipation without wind.
Multiple agencies, including hazmat teams and the Oklahoma National Guard, were deployed to contain the leak, monitor air quality, and support first responders in the emergency situation.
Authorities lifted the shelter-in-place order late Thursday morning after the leak stopped, but cleanup efforts in Weatherford, a city of 12,000, are expected to continue for several days.
