SK Hynix—Fluorine gas leak at SK Hynix Cheongju plant hospitalized 7 workers, prompted nationwide chip-safety inspections
A fire in a gas room connecting the M15 and M15X fabrication buildings at SK Hynix's Cheongju campus caused a fluorine gas leak on June 1, 2026, hospitalizing seven workers and prompting evacuation of roughly 3,600 employees. The plant continued operating while SK Hynix investigated with authorities. In response to this and other recent chip-sector accidents, South Korea's Ministry of Employment and Labor launched safety inspections at 25 semiconductor manufacturers, including SK Hynix, beginning June 26, 2026, covering hazardous-material handling, chemical leak prevention, and fire/explosion protocols.
