A container of dry nitrocellulose started a fire eventually causing a stockpile of ammonium nitrate to explode.

Ammonium nitrate is an oxidiser similar to those used in explosives it provides oxygen so the chemical reaction is much faster and more energetic.

A pair of explosions erupted in Beirut, Lebanon creating a wave of destruction that claimed more than 150 lives and injured thousands more. The explosion was caused when dozens of bags of fireworks being kept in a factory that was housing 2,400 tons of ammonium nitrate accidentally ignited. The seismic impact of the blast was recorded hundreds of kilometres away. It levelled dozens of buildings, stretching from Beirut’s industrial waterfront to residential neighbourhoods and popular tourist districts.
