Residents of Teutopolis, Illinois have been allowed to return to their homes after being evacuated due to a semi-truck crash that released thousands of gallons of toxic ammonia. The crash resulted in five deaths and multiple injuries. The semi-truck was carrying about 7,500 gallons of anhydrous ammonia, and an estimated 4,000 gallons were released during the accident. However, testing has indicated that the danger from the ammonia has dissipated, and officials have deemed it safe for residents to return home.
The crash occurred on US Highway 40, and parts of Teutopolis were evacuated due to the plume from the ammonia leak. Emergency crews have been working to contain the leak, and the crashed tanker has been drained and taken to a secure location for investigation. The National Transportation Safety Board and the Illinois State Police are both investigating the cause of the accident. In addition to the residents who were evacuated, at least five people were airlifted to local hospitals for treatment. Effingham County, where the crash occurred, has an estimated population of about 34,000.
Anhydrous ammonia is a highly toxic substance that can cause irritation and burns to the skin, eyes, and respiratory system. It can be fatal in high levels of exposure. The leak caused dangerous air conditions in the area, prompting the evacuation of residents. Effingham County is located about two hours south of Illinois’ capital, Springfield.
