BARBERTON -- Hazardous materials teams have determined that a white, powdery substance sent in an envelope to a Barberton company posed no danger.

A worker at Babcox & Wilcox on South Van Buren in accounts payable opened the envelope and was exposed to the powder shortly before noon. The woman's eyes began to water and she was taken to the B&W on-site clinic to be treated.

Hazmat teams were called in to test the substance and secure the building. Anyone who came into contact with the woman also had to be checked by medical crews.

After completing tests, it was determined the substance was not hazardous in any way.

The worker, who reportedly showed no symptoms of illness, was treated and released on scene.

Operations at B&W returned to normal by 3:30 p.m.

Approximately 1,200 employees work on the B&W campus in Barberton, with about 800 employees in the affected building.
