Arizona highway closes after nitric acid leaks from tanker truck crash

Residents near the deadly accident on Interstate 10 outside Tucson told to evacuate on Tuesday

The deadly crash of a commercial tanker truck caused hazardous material to leak onto Interstate 10 outside Tucson on Tuesday, shutting down the key highway through Arizona and forcing evacuations near the accident.

Residents within a half-mile (800 meters) were ordered to leave and those within a mile (1.6km) were told to shelter in place for several hours after liquid nitric acid was determined to be leaking from the tanker, the Arizona department of public safety said.
