A married father of six children was killed this week while working at Cleveland-Cliffs’ Burns Harbor steel plant in Porter, Indiana, according to union officials representing workers at the site. The man died in an accident while operating a pot hauler, a specialized heavy vehicle used to move molten slag and liquid metal through steel mills. His name and age have not been released.
The death was first reported by ABC7 Chicago, which cited United Steelworkers Local 9231 as the source confirming that a father of six was killed at the plant. Mike Millsap, speaking for the union, said the incident happened earlier in the week; the outlet reported the man was married, though the exact nature of the deadly incident was not yet known at the time of publication. ABC7 said it had reached out to local officials for more information.
Pot haulers, sometimes called slag pot carriers, are among the largest and highest-risk mobile machines used in steelmaking, built to haul hundreds of tons of molten slag and metal across mill roads. Operators face extreme heat exposure alongside the collision hazards inherent to any operation involving oversized, heavy equipment moving through active industrial yards, according to research on the vehicles published by ResearchGate.
A Massive Plant on Lake Michigan
Burns Harbor is Cleveland-Cliffs' second-largest facility in the country, equipped with two blast furnaces capable of producing nearly 5 million net tons of raw steel a year, per the company's own operational profile. The plant sits along Lake Michigan roughly 50 miles southeast of Chicago, with direct port, rail, and highway access that makes it a linchpin of the region's steel economy.
Northwest Indiana produces roughly one-third of all raw steel made in the United States, with nearly a million workers employed across heavy industry and manufacturing in Lake, Porter, LaPorte, and Montgomery counties, according to figures compiled by the Allen Law Group. That concentration of industrial labor means fatal accidents like this week's carry weight far beyond a single shift or a single plant, touching a workforce that stretches across the region.
What Happens Next
Workplace fatalities in Indiana trigger mandatory investigations by the Indiana Occupational Safety and Health Administration, a division of the state's Department of Labor tasked with inspecting incident sites, evaluating safety standards, and determining whether penalties are warranted. Fatality investigations from the agency typically examine equipment defects, hazard analyses, and training protocols, according to a description of the process from Finderson Law. No timeline for IOSHA's review of this week's death has been released.
The accident comes months after Cleveland-Cliffs announced in April that it would idle finishing and plate mill lines at Burns Harbor as part of a broader consolidation of its Northwest Indiana steelmaking operations toward its Indiana Harbor facility in East Chicago, a shift Hoodline previously reported affected plate production while core raw steelmaking continued at the site. That reshuffling has kept worker safety protocols and staffing levels a focal point for union representatives and state inspectors watching the plant.
A Site With a Troubled Safety Record
This is not the first fatal incident at Burns Harbor. In April 2015, a 53-year-old contractor was found dead inside an elevator shaft at the facility while performing maintenance work, under prior owner ArcelorMittal, according to a report at the time from WOWO News.
The plant has also drawn recent regulatory scrutiny beyond workplace safety. In August 2024, the U.S. Environmental Protection Agency announced a settlement requiring Burns Harbor to install video monitoring and enhanced process controls, and to pay $248,396 in penalties, after excessive emissions and molten material overflows during furnace loading violated the Clean Air Act. Separately, Cleveland-Cliffs agreed in February 2022 to pay $3 million in civil penalties after an August 2019 equipment failure at the plant discharged toxic cyanide and ammonia into the Little Calumet River, a spill that killed fish and forced a seven-day closure of nearby Lake Michigan beaches, per the EPA.
Fatal accidents involving heavy equipment are not unique to Burns Harbor. In January 2021, Indiana OSHA fined an East Chicago steel mill $21,000 after a worker was fatally struck by a heavy coil tractor, with inspectors finding uncorrected equipment defects including non-functional vehicle horns in high-traffic zones, according to Occupational Health & Safety. Cleveland-Cliffs, headquartered in Cleveland, Ohio, is North America's largest producer of flat-rolled steel and the country's second-largest steelmaker overall, employing roughly 25,000 people as of last year, per Wikipedia's corporate profile of the company.
