What chemical was involved in the catastrophic explosion in Lebanon's capital?

The catastrophic explosion in Lebanon's capital, Beirut, was primarily attributed to the detonation of approximately 2,700 tons of ammonium nitrate. Ammonium nitrate is a chemical compound often used in fertilizers and is known for its potential to cause massive explosions under certain conditions, especially when improperly stored. In this case, the ammonium nitrate had been stored unsafely for an extended period in a warehouse at the port, leading to a tragic and devastating explosion that resulted in significant damage and loss of life.

The context surrounding ammonium nitrate underscores its hazardous nature; when exposed to heat or fire, it can decompose explosively. The sheer volume involved in this incident magnified its destructive potential, causing widespread devastation in the surrounding area. Understanding this chemical's role in the explosion highlights the importance of proper storage and handling procedures for hazardous materials to prevent similar accidents in the future.
