A subcontractor in his 40s died at Hyundai Steel’s Dangjin plant on Saturday after being caught inside slag-processing machinery during a maintenance job, the latest fatal crush at a major Korean mill to draw labor-ministry scrutiny. Fire crews found the man in cardiac arrest and rushed him to a hospital, where he was pronounced dead.
What happened at the Songak plant
Fire officials said the accident occurred around 10:40 a.m. at the steelworks in Songak-eup, Dangjin, South Chungcheong Province. Hyundai Steel said the worker, employed by an outside partner firm, was servicing equipment that handles slag, the molten waste left from steelmaking.
Police told reporters they are tracing how the repair was authorized and whether lockout or guarding procedures failed before the machinery moved. Prosecutors will decide whether to apply South Korea’s Serious Accidents Punishment Act, which can hold company officials criminally liable when safety systems break down.
Regulators move on the equipment
YTN reported that the Ministry of Employment and Labor inspected the site and ordered a work stoppage on the affected unit while investigators interview coworkers. Union officials at heavy-industry sites have pressed Hyundai Steel and its contractors for years to tighten maintenance protocols on large rotating gear, where even brief lapses can trap workers between drums and conveyors.
Hyundai Steel issued a statement praying for the deceased and apologizing to the family, adding that it would cooperate with authorities and review steps to prevent a repeat. The Dangjin complex is one of the company’s largest coastal mills, feeding flat products to shipbuilders and automakers already on edge after a string of industrial deaths this year.
What comes next
Bereaved relatives were arranging funeral rites Monday while labor inspectors combed maintenance logs and contractor safety plans. Any finding that required anti-entrapment devices were missing or bypassed would sharpen the criminal inquiry and could ripple through other mills running similar slag lines.
For residents in Dangjin, the death is another reminder that Korea’s steel boom still relies on hazardous turnaround work performed by subcontractors who rotate through high-risk tasks between scheduled outages. Investigators said they expect preliminary conclusions on causation within weeks, though prosecutions under the serious-accident law often take months.
Labor unions representing metal workers planned memorial vigils outside the plant gate Monday evening, calling for mandatory lockout-tagout audits on every maintenance ticket. Opposition lawmakers said the accident showed gaps in contractor oversight at conglomerate sites that report record exports even as subcontractor injury rates remain elevated compared with in-house staff.
