U.S. Department of Labor Cites Wisconsin Company For Exposing Employees to Machine Hazards

NIAGARA, WI The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) has cited Koller Industries ‒ operating as Aurora Castings Services ‒ for continually exposing employees to machine hazards at the facility in Niagara, Wisconsin. The company faces $206,291 in penalties.

OSHA cited Aurora Castings for failing to use guards on bench and grinder stands, train employees on lockout/tagout procedures and properly set grinder tongue and work rest adjustments; exposing employees to hazards associated with grinding wheel breakage; allowing employees to use damaged flexible electrical cords, and not properly covering electrical openings. OSHA cited the company for similar machine hazards following a November 2015 inspection.

“The failure to properly test grinding wheels for defects, and use machine guarding and safety procedures exposes employees to serious injuries,” said OSHA Area Director Robert Bonack, in Appleton, Wisconsin. “Employers should develop a comprehensive safety and health program to ensure that workers are provided a safe and healthful workplace.”

The company contested the citations and will now appear before the independent Occupational Safety and Health Review Commission.

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to help ensure these conditions for America’s working men and women by setting and enforcing standards, and providing training, education, and assistance. For more information, visit
