(CBS) — The federal Occupational Safety and Health Administration is proposing fines and demanding changes at the Postal Service’s Lincoln Park office.

When OSHA received a complaint in January about unsafe working conditions in the facility at 2643 N. Clark St., it sent inspectors who found seven violations. It said, in a statement, that two were recurring violations, problems they have seen in other postal facilities — electrical outlets not used in accordance with manufacturer’s recommendations and improperly grounded fans. The inspectors also found unapproved electrical equipment and improperly spliced cords.

OSHA is proposing fines totaling $63,540. The Postal Service says it is addressing the problem.

“The United States Postal Service takes the safety and well-being of our employees seriously,” said spokesman Mark Reynolds. “We are taking the necessary measures to address the conditions cited by OSHA, and will stress the importance of maintaining safe working conditions in all our facilities.”

He did not give a timetable for compliance.
