Storage of fertilizer grade ammonium nitrate (FGAN) is common worldwide. The material is stable when stored at ambient temperatures. However, ammonium nitrate is explosive when exposed to higher temperatures and/or a shock wave source. The presence of even 0.2% carbon adds to the blast potential. This paper summarizes the key finding of an ammonium nitrate explosion that occurred at a FGAN storage facility on 17 April 2013 in West, Texas, USA. 15 people were killed including12 emergency responders who were fighting a fire that occurred on the property before the explosion. Over 260 were injured. The key lessons learned are reviewed and recommendations are offered below.
