[PAR] [TLE] PEPCON disaster [SEP] The PEPCON disaster was an industrial disaster that occurred in Henderson, Nevada on May 4, 1988 at the Pacific Engineering and Production Company of Nevada (PEPCON) plant.  The conflagration and subsequent explosions killed two people, injured 372 others, and caused an estimated US$100 million of damage.  A large portion of the Las Vegas Valley within a 10 mi radius of the plant was affected, and several agencies activated disaster plans. [PAR] [TLE] Ammonium perchlorate [SEP] Ammonium perchlorate ("AP") is an inorganic compound with the formula NHClO.  It is a colorless or white solid that is soluble in water.  Perchlorate is a powerful oxidizer and ammonium is a good fuel.  This combination explains the usefulness of this material as a rocket propellant.  Its instability has involved it in a number of accidents, such as the PEPCON disaster.
