Terrible tragedy. A lot of lives lost, people that let this happen need to be held responsible including the government for allowing dangerous chemicals to be stored in such close proximity to populous areas since 2014. Clearly, history is not important and taken seriously. The Toulouse chemical factory explosion on 4th of October 2001 is an example of how dangerous ammonium nitrate is, the tragedy then decimated an entire factory, leaving only a crater and two thirds of the city was affected. The only difference between the Toulouse chemical factory explosion and the Beirut warehouse explosion is the cost of lives, with the former taking 29 lives and the later taking 135 lives and still counting as rescue operations continue
One can argue that one is a warehouse and the other a factory. Look at the 2015 Tianjin explosions at a container storage station at the Port of Tianjin, although the chemicals that cause the explosions are not the same but it shows the potential of a great tragedy waiting to happen if you store large quantities of dangerous chemicals near populous areas.
For now, let's hope the city of Beirut can recover from this tragedy as well as tackle any outbreak of Covid-19 simultaneously. Let the world learn from this tragedy and not let history repeat itself.
