BREAKING: Truck Carrying Hazardous Materials In Arizona Overturns, ‘Shelter In Place’ Within Mile Radius


It’s one incident after another with these toxic chemicals being transported across the United States.

Breaking reports from Tucson, Arizona, indicate a truck carrying hazardous materials overturned on I-10.

Authorities reportedly issued a hazmat alert, and a ‘shelter in place’ warning is in effect for anyone within a one-mile radius of the site.

“Police scanners are reporting the toxic chemical that is currently leaking is nitric acid which is extremely toxic if you get in contact,” according to @rawsalerts
