According to the headquarters, at about 8:15 p.m. the previous day, a fire broke out in the NCIA's fifth-floor computer room due to a lithium-ion battery explosion. While 13 workers were replacing lithium batteries, sparks flew from one battery and the fire spread. One person suffered first-degree burns, and about 100 people evacuated on their own.
Fire authorities deployed more than 200 personnel, including firefighters, and 64 fire engines, bringing the main blaze under control at about 6:30 a.m. that day. Fire authorities are venting smoke and heat from the NCIA computer room and removing the burned lithium battery packs to the outside to cool them in a mobile water tank.
