OSHA is proposing nearly two million dollars in fines against a Wisconsin corn milling facility, after five employees were killed in 12 others injured in a grain dust explosion.

Among those injured in the May 31, 2017 incident at Didion Milling, Inc.: a 21-year-old employee who suffered a double leg amputation after being crushed by a railcar.

A preventable tragedy

OSHA found that the explosion likely resulted from Didion’s failures to correct the leakage and accumulation of highly combustible grain dust throughout the facility and to properly maintain equipment to control ignition sources. OSHA cited Didion’s Cambria facility with 14 willful – including eight willful per-instance egregious– and five serious citations, most involving fire and explosion hazards. The company has been placed in OSHA’s Severe Violator Enforcement Program.

“Didion Milling could have prevented this tragedy if it had addressed hazards that are well-known in this industry,” said OSHA Regional Administrator Ken Nishiyama Atha, in Chicago. “Instead, their disregard for the law led to an explosion that claimed the lives of workers, and heartbreak for their families and the community.”

A variety of violations

The egregious willful citations were issued for violating OSHA’s Grain Handling standard by failing to perform required maintenance on operating equipment and implementing a housekeeping program to control dust accumulations. Willful citations were issued for failure to shut down ignition sources, prevent static electricity discharge, provide adequate personal protective equipment to employees, correct malfunctioning dust collection systems, maintain equipment safety controls, and have an emergency alarm system. Serious citations addressed hazards associated with fires and explosions, and the lack of employee training.

Proposed fines are $1,837,861.
