The company, Jiangsu Tianjiayi Chemical Company, stored dangerous chemical waste illegally in its warehouse for a long time and that caused the blast, said the administration.

The explosion, which took place at about 2:48 pm on March 21 in a chemical industrial park, also caused the hospitalization of 640 people and an economic loss of 1.99 billion yuan ($287 million).
