The plant in Shandong province which caught fire on August 22 produced hundreds of thousands of tons of adiponitrile – a toxic colorless liquid which releases poisonous gases when it reacts with fire, local media reported.
China has been hit by a wave of massive blasts at its chemical facilities this month. Earlier in August, nearly 160 people were killed and around 700 injured in explosions at a warehouse storing hazardous chemicals in Tianjin port.
Fifteen people still remain missing following the tragedy, authorities said on Monday. Cleanup crews are still struggling with cyanide contamination in the area.
