PORTLAND, Ore. — Eleven people were hospitalized with respiratory problems Wednesday following a chemical mishap at a Darigold milk plant in Portland, Ore., KVAL CBS 13 reported.
According to Portland Fire and Rescue spokesman Paul Corah, a tanker trunk driver mistakenly hooked up a wrong hose and pumped 450 gallons of a corrosive acid into a tank that contained 1,150 gallons of a caustic liquid.
The mixture set off a chemical reaction that released toxic gas.
The plant was evacuated and 11 people were decontaminated and placed in protective suits before being taken to the hospital.
The facility produces “ultra-pasteurized” milk products.
