It is not the first time that an explosion such as this has happened in the state of Texas; in 1947 in Texas city, Texas an explosion that caused nearly 600 deaths had ammonia as a key part in the blast (Jonsson, 2013).

It has a melting point of around -108 degrees Fahrenheit and an explosive range between a Lower explosive limit (LEL) of 15% and an Upper explosive limit (UEL) of 28% when mixed in air. Ammonium nitrate is typical found and used in its prill form where it is spread across the fields as a fertilizer. Ammonium Nitrate does not typical, under normal circumstances, pose an explosive hazard alone by itself but when combined with some sort of fuel it will act as an oxidizer during that process, literally adding fuel to the fire. “Both of these common fertilizers can become explosive under the right conditions.” (Fernandez & Schwartz, 2013)
