ROCHESTER, Minn. – Chemicals that leaked in a truck rollover off Interstate 90 south of Rochester Wednesday pose no risk to the public, investigators said. The Minnesota Pollution Control Agency listed the cargo as:
> Sodium hydroxide.
> Hydrogen peroxide.
> A chlorite solution.
> A food additive.
> An antifoam.
The list corrected earlier information from the scene that included table salt. New to the list was sodium hydroxide, sometimes called caustic soda or lye — a common ingredient in cleaners and soaps. The driver of the truck managed his way out of the cab right way. He was assessed for medical issues and was not transported to a hospital. The I-90 ramp where the accident occurred remained closed at mid-morning.
