An auto insulation manufacturer in suburban Toledo, Ohio faces $569,463 in proposed penalties after an OSHA investigation following a report that a machine amputated a 46-year-old worker's right hand, wrist and part of his forearm.

Investigators found the injury occurred while the worker at Autoneum North America was guiding waste materials into a shredding machine. His arm was caught in the machine's point of operation - a circular drum that shreds the fabric fibers for reuse. OSHA found the company failed to equip the machine with adequate safety guards when the Dec. 23, 2016, injury occurred. The agency issued three willful and two repeated violations of machine safety procedures.

"This incident illustrates why companies must evaluate machine safety procedures to ensure they are adequate and effective in protecting workers from injuries on the job," said Dorothy Dougherty, deputy assistant secretary of labor for occupational safety and health. "In addition to being the law and the right thing to do, safe workplaces are an important component in supporting and sustaining job growth in America."
