7. Tianjin Explosions
One of the most recent industrial accidents occurred on August 12, 2015, in Tianjin, China. A series of explosions at a warehouse containing dangerous chemicals killed 173 people while hundreds of others were injured. The two explosions took place very fast, within 30 seconds of each other, but the second was larger detonating about 800 tons of ammonium nitrate. Fire, caused by the explosions, continued to burn for days and further caused several other explosions.
