A fire broke out at a chemical manufacturing facility in Haknam-ri, Onsan-eup, Uljin County, Ulsan.
According to Yonhap News, the fire started at approximately 9:41 a.m. on October 14, and firefighting authorities are currently working to extinguish the blaze.
Fire officials issued a Level 1 response at 10:04 a.m., deploying over 200 personnel, three helicopters, and one large-capacity firefighting vehicle to combat the fire.
At the time of the incident, 16 workers were present at the facility, but all were evacuated safely, and there have been no reported injuries.
The fire originated from an outdoor storage tank at the facility, which contained 8,000 liters of toluene, a Class 4 hazardous material.
Due to the presence of other chemical storage tanks nearby, firefighting authorities are taking precautions to prevent the fire from spreading.
Some operations at the nearby S-Oil Shahin Project Package 1 site were also halted, leading to the evacuation of approximately 7,000 workers to a safe area.
Police and fire officials reported hearing an explosion and electrical sparks near the tank's inlet piping before the explosion occurred. They plan to investigate the exact cause of the fire once it is fully extinguished.
Uljin County has issued a safety alert, advising vehicles to detour and urging nearby residents to remain cautious.
