Seven Casualties in Sudden Explosion at Hanwha Aerospace Plant

An explosion at a Hanwha Aerospace facility in Daejeon, South Korea, left seven people dead or injured. The incident occurred suddenly around 10:59 a.m. on June 1st, characterized by a flash of light and an immediate blast, with no discernible warning signs.

According to a report submitted by the Fire Department to lawmaker Park Jeong-hyun of the Democratic Party, CCTV footage captured the moment of the explosion. The blast appears to have originated from the exterior of Building 56, a cleaning facility within the Daejeon plant. The fire subsequently spread following the initial explosion.

Investigators have tentatively identified the 'Separation Cleaning Room 1' within the facility as the origin point. This room is used for cleaning pipes, valves, and equipment contaminated with solid rocket fuel, a propellant used in rockets. The process involves removing residue with a spatula-like tool and washing equipment in a water tank using high-pressure cleaning.

The Fire Department has concluded that the propellant caused the explosion, but the specific ignition source remains unconfirmed. The investigation is ongoing to determine the exact cause of the blast that tragically claimed seven lives.
