Three people were killed and two injured after an explosion and fire at a paint-material production factory in Cheonan. Firefighters responded late Friday morning and extinguished the blaze after several hours.
Early reports establish the casualty count and the industrial setting, but not the cause. That distinction matters: an explosion at a chemical-related facility can have several possible triggers, and assigning blame before a technical investigation would be premature. The next important information will come from fire investigators and workplace-safety authorities.
