Daejeon Hyundai Outlet Fire Concluded to Be Caused by Overheating of Cargo Truck Exhaust Pipe

[Asia Economy (Daejeon) Reporter Jeong Il-woong] The fire at Daejeon Hyundai Premium Outlet was concluded to have been caused by overheating of a cargo truck exhaust pipe.

The Daejeon Police Agency's Violent Crime Investigation Unit held a briefing on the 26th to announce the fire investigation results from the National Forensic Service regarding the Hyundai Outlet fire.

According to the police, the National Forensic Service analyzed that the fire occurred due to overheating of the exhaust pipe of a 1-ton cargo truck parked in the underground parking lot loading area of Hyundai Outlet at the time of the fire.

The key point is that the Diesel Particulate Filter (DPF) installed on the accident vehicle increased output to remove exhaust smoke, causing the temperature of the exhaust pipe connected to this device to rise. The heat generated at this time likely ignited waste boxes and waste paper stacked under the cargo truck.

The Diesel Particulate Filter is a reduction device that collects harmful substances such as hydrocarbon residues generated from incomplete combustion of diesel, filters them, and then burns them again at a high temperature of 550 degrees Celsius to reduce pollutants. The conclusion is that the high-temperature heat and exhaust gas generated from this device accumulated and caused the ignition.

The police also confirmed through analysis of fire equipment log records that the sprinklers near the cargo truck did not operate normally at the time of the fire.

Some firefighters testified at the scene that the sprinklers were not working during the fire. However, the police explained that some sprinklers operated in areas other than the ignition point.

On the day, a police official said, “When checking the log records from the fire alarm panel controlling the fire equipment, it was investigated that the system function was stopped at the time of the fire. It is understood that the system function was stopped due to fire facility maintenance, but it is still difficult to mention the timing and the party who stopped the function.”

Meanwhile, the Hyundai Outlet fire occurred around 7:45 a.m. on September 26 in the underground parking lot of Hyundai Outlet located in Yongsan-dong, Yuseong-gu, Daejeon, resulting in 8 casualties.
