(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.
