Meanwhile, warehouse did not have certification to handle dangerous goods between October 2014 and June 2015 but continued to work with hazardous chemicals, Xinhua reported.
According to an assessment by government environmental inspectors published in 2014, the warehouse was designed to store dangerous and toxis chemicals. Moreover, it held ammonium nitrate, potassium nitrate and calcium carbide.

Tianjin city is one of China's biggest cities with a population of nearly fifteen million people and Wednesday night began with explosions that were so large and sent shockwaves through apartment blocks several kilometers away.
Explosions at a chemical warehouse left more than a hundred people dead and hundreds injured.
Many of firefighters were already on the scene before the explosion and rescuers were attempting to remove 700 tons of deadly sodium cyanide from the area.
Prosecutors in Tianjin said earlier they were investigating two senior officials from Binhai district on suspicion of corruption. Moreover, authorities promised to investigate the cause of the disaster.
According to authorities, at least 57 people are still missing. This explosion was the world’s 10th largest and seen by satellities in space.
