Since then, Busan city fire disaster headquarters will conduct regular inspections. < / P > < p > the official said, “the laws related to the management of ammonium nitrate are relatively scattered, and the relevant responsibilities are divided into different departments.

At the same time, the terminal operators also stressed that the residence time of these ammonium nitrate containers would not exceed 10 days, because the terminal operators would charge additional fees for hazardous substances.
