The U.S. Department of Labor’s Occupational Safety and Health Administration announced Tuesday that it has cited Miami Valley Polishing LLC for 14 – including seven repeat – safety and health violations at the company’s Piqua facility.

OSHA said it conducted an inspection in July as a follow-up to a May 2011 inspection that resulted in citations for failing to evaluate workers’ exposure to chromium and lock out the energy sources of machinery, among other violations.

Proposed fines for the most recent inspection total $57,144.

“Miami Valley Polishing is compromising the health and safety of its workers by allowing previously cited deficiencies to continue without correction,” said Bill Wilkerson, OSHA’s area director in Cincinnati. “Training employees and evaluating their exposure to hazardous chemicals such as chromium is vital to their long-term safety and health. OSHA is committed to protecting workers on the job.”

A representative for the company couldn’t be immediately reached for comment.
