QUINCY, Ill. (AP) - Officials say roughly two dozen people were sickened by fumes from hydrochloric acid at a plant in the Mississippi River city of Quincy.
All the workers affected Tuesday morning at Manchester Tank were taken to a hospital, though their injuries were not thought to be life-threatening. Most were later released from the hospital.
Mickie Coggin, a spokesman for Tennessee-based McWane Inc., which owns Manchester Tank, says an investigation is under way into what caused the accident.
But Coggin says there was no actual spill of the acid, only a leak of fumes - perhaps from some air-scrubbing equipment.
Manchester Tank makes pressure vessels for the containment of propane, compressed air and chemicals.
