SEATTLE — More than three-quarters of janitorial service companies investigated nationally by the U.S. Department of Labor's Wage and Hour Division in the past two fiscal years failed to pay low-wage workers fairly and legally for the work they do. Of the division's 1,221 janitorial industry investigations, 76 percent resulted in violations and led to the recovery of $7.9 million in unpaid wages for nearly 10,000 workers.

HOUSTON — A 31-year-old worker was the second person killed in a year at Madden Bolt Corp. when a cutting-table explosion in August 2014 hurled the employee and a steel plate into the air. The plate then landed on the fallen worker, U.S. Department of Labor Occupational Safety and Health Administration investigators determined. As a result, OSHA has cited the Houston-based employer for 10 serious violations.

In September 2013, a forklift driver at Madden Bolt died after the machine turned over and pinned him underneath.

HOUSTON — Combustible dust left uncontrolled or suspended in the air can explode, which was one of many safety hazards discovered after an inspection at the Thomas Moore Feed facility in Navasota, Texas, by the U.S. Department of Labor's Occupational Safety and Health Administration.

FRANKLIN, Ohio — Mere months after two employees were injured by dangerous machines, Burrows Paper Corp. again put workers at risk.

This is the fourth time in the past year that Burrows has been cited for hazards at its Franklin food box manufacturing facility.

MADISON, Ohio — Every year, thousands of people are electrocuted at work by current from live wires and energized parts. Electrical current often enters through the skin, muscles or hair and then spikes through the nervous system, burning tissue in patches.

Burns hospitalized him and left him unable to work for more than four months.

DALLAS — The dangers of worker exposure to hexavalent chromium, a known carcinogen that can cause serious long-term health issues, including lung cancer and kidney failure, should have come as no surprise to the Lane Plating Works Inc. owner. Air-monitoring tests told him that workers were being overexposed to the dangerous toxin, but he failed to correct the hazard.
