Officials in Arizona issued evacuation and shelter-in-place orders Tuesday following a collision near Tucson that resulted in a truck hauling liquid nitric acid to leak its load along the interstate.
A crash in south Tucson promoted evacuations and shelter-place-requests for more than four hours after a nitric acid spill, according to the Pima Country Department of Environmental Quality.
The mock disaster was a collision between a freight train and a black Ford truck full of passengers. The accident began with the train derailing and leaking hazardous chemicals across Jackson County. <br/><br/>
