The Lebanese capital of Beirut was rocked by a massive explosion on Tuesday that struck the city’s port, leaving at least 80 dead and thousands injured. It also caused extensive damage to buildings, resulting in hundreds of people being left homeless.
Hassan Diab, the PM of Lebanon, stated that the massive explosion was supposedly caused by 2,750 tons of ammonium nitrate that was stored in a warehouse.

This blast sheds light on the deadly potential of this common agricultural chemical. So, lets understand what ammonium nitrate is and how deadly this chemical can be if preventive measures are not taken.
What is ammonium nitrate?
Ammonium nitrate is a industrial chemical that is mainly used for fertiliser as it is a good source of nitrogen for plants. This chemical is relatively stable under most conditions and is inexpensive to manufacture, making it a popular alternative to other, more expensive nitrogen sources.
It is also one of the main components used in mining explosives, quarrying and civil construction. And, it accounts for 80% of all the industrial explosives used in U.S.
This chemical only ignites under the right circumstances, and these are difficult to achieve. You need extreme circumstances to set off an explosion.
You see, Ammonium nitrate is an oxidiser, drawing oxygen to a fire, therefore making it much more volatile and intense. This is one of the major reasons why most countries have regulations to control its storage to make sure it is safe.
So, what makes ammonium nitrate explosive?
While the chemicals in the air should dissipate fairly quickly, lingering pollutants can cause problems later, for example if they acidify rain. If you look at the smoke that came from the blast it’s this kind of blood red colour . That’s because of the nitrogen oxide air pollutants in it, he said.
It is unacceptable that a shipment of 2,750 tonnes of ammonium nitrate has been present for six years in a warehouse, without taking preventive measures.Two back to back explosions sent shockwaves across the city of Beirut, shattering windows and causing apartment balconies to collapse with in the radius of 10 kms. The blast took place in the city’s port area.
