A Westinghouse plant in Newington New Hampshire is facing $82,000 in fines for workplace safety violations.

The Occupational Safety and Health Administration has cited Westinghouse Electric for allegedly exposing workers to hexavalent chromium at its stainless steel component manufacturing facility in Newington.

In response to a complaint, an OSHA inspection found that employees performing welding work were exposed to airborne concentrations of the carcinogen in excess of permissible limits.

Hexavalent chromium can cause damage to eyes and skin upon contact.
