Military vehicles arrived at the Rang Dong warehouse at around 8 a.m. to prepare for the decontamination.

The five-hour blaze that started at 6 p.m. on August 28 destroyed a third of the inventory at the 6,000-square-meter warehouse belonging to the Rang Dong Light Source and Vacuum Flask JSC. The area within a 500-meter radius of the warehouse has been contaminated with mercury, authorities said.

Before decontaminating the site, personnel must spray water onto half-burnt materials and the storage area to prevent dust and iron particles laced with mercury from spreading. It also serves to lower the surrounding environments temperature as mercury would turn into gas at 30 degrees Celsius or above.
