3M Knew Process Was Dangerous Before Fatal Accident, OSHA Says

In February 2022, a 63-year-old worker was killed at a 3M (NYSE: MMM) plant in Alexandria, Minnesota. The worker became entangled with a machine during the overnight shift.


A few months after the accident, the company assessed its equipment at U.S. and Canadian plants. According to OSHA Regional Administrator Bill Donovan, after 3M completed its investigation, it “determined powered rollers were hazards in need of safety improvement.”


In May 2023, a worker was helping set up a plastic extrusion line at a 3M manufacturing plant in southwestern Wisconsin and died after becoming caught in a machine’s rotating rollers. According to OSHA, the death in Prairie du Chien could have been avoided if the company had followed federal workplace safety regulations and heeded its own advice.
