On June 1, 2026, according to South Korean media JTBC, a fire broke out at the SK Hynix Cheongju 4th Campus factory, leading to the evacuation of approximately 3,600 employees and the transportation of 7 people to the hospital.

According to the article, around 10:32 AM on the 1st, a fire broke out in a gas room on the 6th floor of a factory within the SK Hynix 4th Campus in Cheongju, South Korea. Because the sprinklers inside the factory activated immediately, the fire was reportedly extinguished at an early stage, but in the process, it is believed that some hydrogen fluoride, a toxic substance, leaked, and 7 people reported symptoms such as eye pain and were transported to the company's affiliated hospital.

After the fire, approximately 3,600 employees who were working at the SK Hynix M15 and M15X factories were evacuated. The company stated, "The fire has already been extinguished, and there has been no disruption to the semiconductor manufacturing process." Currently, the police and fire department are conducting a detailed investigation into the cause of the fire and the circumstances of the hydrogen fluoride leak.

Regarding this, South Korean netizens commented, "(Given that an explosion also occurred at the Hanwha Aerospace Daejeon factory on the same day) How can so many accidents happen in one day?" "What about the safety management at the factory?" "I hope the injured are not seriously hurt." "3,600 people evacuated is a pretty big commotion." "A fire starting in a gas room is too scary." "If these kinds of accidents continue, employees won't be able to work with peace of mind," such comments were made.

Additionally, comments such as, "Semiconductor factories handle chemical substances, so hazardous materials are scarier than the fire itself," "If there's a possibility of hydrogen fluoride leakage, I hope they conduct thorough safety checks," "They say there's no disruption to the process, but I'm concerned if there's truly no impact," and "I hope they thoroughly investigate the cause and work to prevent recurrence," were also seen.
