One final missing person who had been buried under the debris of Unit 5 of the boiler tower at the Ulsan Thermal Power Plant, which collapsed on the 6th, has been recovered. It came nine days after the accident.
According to fire authorities on the 14th, rescuers recovered A, believed to be a man in his 60s and the last missing person, at 9:57 p.m. A was pronounced dead at about 10:04 p.m.
The accident occurred at about 2:02 p.m. on the 6th at the Ulsan Thermal Power Plant in Namhwadong, Nam-gu, Ulsan, when the 60-meter-high Unit 5 boiler tower collapsed during dismantling. While carrying out a "pre-weakening operation" (cutting columns and steel structures in advance so that a large structure can easily fall in the intended direction during demolition) to dismantle the aging boiler tower, which had been in service for 44 years since completion, the boiler tower suddenly came down.
Of the nine workers at the site at the time, seven were buried, and all seven buried died.
The National Fire Agency lifted the national fire mobilization order, which had been issued at 3:13 p.m. on the day of the accident, as of 10:17 p.m. on this day.
This boiler tower dismantling project was ordered by Korea East-West Power (EWP) and built by HJ Shipbuilding & Construction, with blasting specialist Korea Kacoh contracted to carry it out. East-West Power and HJ Shipbuilding & Construction issued an official apology only on the 13th, a week after the accident.
