On the 26th at night, a fire that broke out at the National Information Resources Service in Daejeon was brought under control in about 10 hours.
According to the Daejeon Fire Headquarters on the 27th, the blaze began around 8:20 p.m. on the 26th with a lithium-ion battery explosion in the main building's fifth-floor computer room at the agency in Hwaam-dong, Yuseong District. Fire authorities deployed about 170 personnel and 63 pieces of equipment and contained the major flames around 6:30 a.m. on the 27th, then focused on ventilating smoke thereafter.
At the scene, 192 lithium-ion battery packs were stacked, and a significant portion was burned and destroyed. Out of concern for damage to computer data, gas-based fire suppression such as carbon dioxide was used instead of water at first, slowing the pace of extinguishing. When some flames reignited, crews ended up separating the batteries and carrying out water spraying with a minimum amount of water, but they faced major difficulties in suppression.
The fire was found to have occurred during the process of cutting power while replacing batteries. One employee of a partner company who was working at the site suffered first-degree burns to the face and arm.
Meanwhile, several government services were temporarily shut down due to the fire. The affected systems were identified as 12 in grade 1 and 58 in grade 2. Notably, mobile ID, the National Complaints Portal, the government's online civil service Government24, and the homepages of government ministries including the Ministry of the Interior and Safety and the Ministry of Economy and Finance are experiencing disruptions.
